"There is evidence to suggest that adiponectin plays a role in migraine. Increase in body fat elevates adiponectin and leptin secretion which in turn impair inflammatory processes that could be contributing to migraine risk. In episodic migraine patients, adiponectin was associated with migraine severity and predictive of acute treatment response. Serum adiponectin levels are increased in women chronic daily headache sufferers."
] | [] | [
"Increase in body fat, especially in gluteofemoral region, elevates adiponectin and leptin secretion which in turn impair inflammatory processes that could be contributing to migraine risk.",
"CONCLUSION: In this pilot study of women episodic migraineurs, the HMW : LMW ADP ratio level was associated with migraine severity and predictive of acute treatment response. ADP and the HMW : LMW ratio of ADP represent potential novel biomarkers and drug targets for episodic migraine.",
"Specifically, neurotransmittors such as serotonin, peptides such as orexin, and adipocytokines such as adiponectin and leptin have been suggested to have roles in both feeding and migraine. ",
"Obesity can be considered as a proinflammatory state in which increased inflammatory mediators, vascular hyperreactivity, plasma calcitonin gene-related peptide (CGRP) concentrations and decreased adiponectin concentrations are observed. These alterations can cause an increase in the frequency of migraine attacks developed of central sensitization, and thereafter, chronic migraine.",
"Specifically, neurotransmittors such as serotonin, peptides such as orexin, and adipocytokines such as adiponectin and leptin have been suggested to have roles in both feeding and migraine. ",
"Several adipocytokines appear to play an integral role in feeding and obesity--and have also been linked to pain. Among these proteins are adiponectin and leptin. The author reviews the regulation of adipose tissue and feeding and provides an in-depth examination of adiponectin and leptin and their association with migraine.",
"CONCLUSION: Serum adiponectin levels are increased in women chronic daily headache (CDH) sufferers.",
"n this review we discuss the basic science of adiponectin and its potential connection to the pathophysiology of migraine. Future research may focus on how adiponectin levels are potentially altered during migraine attacks, and how that information can be potentially translated into migraine therapy.",
"Collectively, the results of our analysis suggest that a link between serum adiponectin and migraine remains elusive, at the best",
"Future research may focus on how adiponectin levels are potentially altered during migraine attacks, and how that information can be potentially translated into migraine therapy."

55253d7087ecba3764000008 | summary | Which phenomenon is described as oncogene addiction? | [
" Oncogene addiction describes the curious acquired dependence of tumor cells on an activated oncogene for their survival and/or proliferation, a phenomenon that has important implications for the success of targeted cancer therapies. However, the mechanisms explaining oncogene addiction remain elusive. We propose that addiction may be an illusion generated as a consequence of differential attenuation rates of prosurvival and proapoptotic signals emanating from an oncoprotein acutely following its inactivation. According to this model, which we call oncogenic shock, prosurvival signals dissipate quickly on oncoprotein inactivation whereas proapoptotic signals linger sufficiently long to commit the cell to an apoptotic death.

"Tumor cell growth and survival can often be impaired by inactivating a single oncogen- a phenomenon that has been called as \"oncogene addiction.\" It is in such scenarios that molecular targeted therapies may succeed.",
"The clinical efficacy of tyrosine kinase inhibitors supports the dependence of distinct subsets of cancers on specific driver mutations for survival, a phenomenon called \"oncogene addiction.",
"A given tumor is usually dependent on the oncogene that is activated in the respective tumor entity. This phenomenon called oncogene addiction provides the rationale for attempts to target oncogene products in a therapeutic manner, be it by small molecules, by small interfering RNAs (siRNA) or by antigen-specific T cells.",
"It has long been established that cancers can become addicted to particular oncogenes. Despite the genetic complexity that governs tumorigenesis, certain cancers can exhibit a critical dependency on the expression of a single oncogene, which when removed leads to death of the cancer cell. ",
"We now know that oncogenes are dysfunctional proto-oncogenes and that dysfunctional tumor suppressor genes contribute to the cancer process. Furthermore, Weinstein and others have hypothesized the phenomenon of oncogene addiction as a distinct characteristic of the malignant cell. It can be assumed that cancer cells, indeed, become dependent on such vital oncogenes. The products of these vital oncogenes, such as c-myc, may well be the Achilles heel by which targeted molecular therapy may lead to truly personalized cancer therapy.",
"Despite complex genomic and epigenetic abnormalities, many cancers are irrevocably dependent on an initiating oncogenic lesion whose restoration to a normal physiological activation can elicit a dramatic and sudden reversal of their neoplastic properties. This phenomenon of the reversal of tumorigenesis has been described as oncogene addiction. Oncogene addiction had been thought to occur largely through tumour cell-autonomous mechanisms such as proliferative arrest, apoptosis, differentiation and cellular senescence. ",
"Cancers can exhibit marked tumor regression after oncogene inhibition through a phenomenon called \"oncogene addiction.\" The ability to predict when a tumor will exhibit oncogene addiction would be useful in the development of targeted therapeutics. Oncogene addiction is likely the consequence of many cellular programs. However, we reasoned that many of these inputs may converge on aggregate survival and death signals.",
"The suppression of oncogenic levels of MYC is sufficient to induce sustained tumor regression associated with proliferative arrest, differentiation, cellular senescence, and/or apoptosis, a phenomenon known as oncogene addiction.",
"Although human cancers have complex genotypes and are genomically unstable, they often remain dependent on the continued presence of single-driver mutations-a phenomenon dubbed \"oncogene addiction.\" Such dependencies have been demonstrated in mouse models, where conditional expression systems have revealed that oncogenes able to initiate cancer are often required for tumor maintenance and progression, thus validating the pathways they control as therapeutic targets.",
"Oncogene addiction is a phenomenon that the survival of cancer cells depends on an activated oncogene or inactivation of tumor suppressor gene, and is regarded as the 'Achilles heel' of the successful molecular targeted therapies in cancer.",
"Inhibition of an initiating oncogene often leads to extensive tumour cell death, a phenomenon known as oncogene addiction. This has led to the search for compounds that specifically target and inhibit oncogenes as anticancer agents.",
"Cancer is a multistep process whereby genetic events that result in the activation of proto-oncogenes or the inactivation of tumor suppressor genes usurp physiologic programs mandating relentless proliferation and growth. Experimental evidence surprisingly illustrates that the inactivation of even a single oncogene can be sufficient to induce sustained tumor regression. These observations suggest the hypothesis that tumors become irrevocably addicted to the oncogenes that initiated tumorigenesis. The proposed explanation for this phenomenon is that activated oncogenes result in a signaling state in which the sudden abatement of oncogene activity balances towards proliferative arrest and apoptosis. Indeed, substantial evidence supports this hypothesis.",
"Cancer cells contain multiple genetic and epigenetic abnormalities. Despite this complexity, their growth and survival can often be impaired by the inactivation of a single oncogene. This phenomenon, called \"oncogene addiction,\" provides a rationale for molecular targeted therapy.",
"Does an activated oncogene that initiates tumor growth need to remain activated to maintain the cancer phenotype? This question has been answered affirmatively by experiments in which doxycycline-regulated oncogene activation induces growth of large tumors that regress completely upon oncogene inactivation--a phenomenon called oncogene addiction. We assemble here the evidence that oncogene addiction is angiogenesis-dependent.",

"FOXOs are reliable markers of longevity."

"yes"

"Forkhead box O (FOXO) transcription factors have a conserved function in regulating metazoan lifespan.",
"In contrast to FoxO1, FoxO3a and FoxO6 were specifically diminished in the CNS of HFD animals possibly contributing to the reduced lifespan observed in these animals.",
"Interestingly, many target proteins of AMPK are so-called longevity factors, e.g., SIRT1, p53, and FoxOs, which not only can increase the stress resistance and extend the lifespan of many organisms but also inhibit the inflammatory responses. ",
"Components of anti-ageing and autophagy include SirTs and FoxOs.",
"Since Sirts and FoxOs are reliable markers of longevity, the results appear to suggest that Longevinex induces longevity after prolonged feeding via induction of autophagy, while it converts death signals into survival signals and provides cardioprotection within a relatively shorter period of time.",
"Forkhead box O (FOXO) transcription factors are involved in various cellular processes, including cell proliferation, stress resistance, metabolism, and longevity",
"In this respect, members of the mammalian forkhead transcription factors of the O class (FoxOs) that include FoxO1, FoxO3, FoxO4 and FoxO6 are increasingly being recognized as exciting prospects for multiple disorders. These transcription factors govern development, proliferation, survival and longevity during multiple cellular environments that can involve oxidative stress. ",
"Here we discuss the fascinating but complex role of FoxOs during cellular injury and oxidative stress, progenitor cell development, fertility, angiogenesis, cardiovascular function, cellular metabolism and diabetes, cell longevity, immune surveillance and cancer.",
"Many longevity genes, e.g. FoxOs and SIRT1, are inhibitors of NF-kappaB signaling. ",
"Interestingly, several longevity genes such as SIRT1, SIRT6, and FoxOs can clearly suppress NF-kappaB signaling and in this way delay the aging process and extend lifespan.",
"Yet, FoxOs also can significantly affect normal cell survival and longevity, requiring new treatments for neoplastic growth to modulate novel pathways that integrate cell proliferation, metabolism, inflammation and survival.",
"These observations link FoxO function in mammalian systems with the evolutionarily conserved role of FoxO in promotion of stress resistance and longevity in lower phylogenetic systems. Furthermore, these findings have implications for aging in higher organisms and in malignant stem cell biology, and suggest that FoxOs may play an important role in the maintenance and integrity of stem cell compartments in a broad spectrum of tissues.",
"Forkhead box O (FoxO) transcription factors are important downstream targets of the PI3K/Akt signaling pathway and crucial regulators of cell fate. This function of FoxOs relies on their ability to control diverse cellular functions, including proliferation, differentiation, apoptosis, DNA repair, defense against oxidative stress and ageing.",
"This brief review focuses on the molecular mechanisms, cellular effects and resulting organismal phenotypes generated by differentially regulated FoxO proteins and discusses our current understanding of the role of FoxOs in disease and ageing processes.",
"In this review, we focus on the several interactions of aging-associated signaling cascades regulated either by Sirtuins and FoxOs or NF-kappaB signaling pathways. We provide evidence that signaling via the longevity factors of FoxOs and SIRT1 can inhibit NF-kappaB signaling and simultaneously protect against inflamm-aging process.",
"In diverse species transcription factors belonging to the forkhead/winged helix box gene, group O (FOXO) subfamily have been found to be crucial in downstream suppression of the life-shortening effects of insulin/insulin-like growth factor-I receptor signalling pathways that, when upregulated, accelerate ageing by suppression of FOXO. ",
"In humans, FOXO3a, as well as FOXO1 and -4, and their downstream effectors, could hold the key to counteracting ageing and common diseases.",
"FOXO transcription factors have important roles in metabolism, cellular proliferation, stress tolerance, and aging. "

"Although there are usually no abnormalities in MFS by routine neuroimaging, in a few cases, contrast enhancement of nerve roots and signs of central nervous system involvement were described supporting the hypothesis of an anti-GQ1b-syndrome, a continuum involving GBS, MFS, and Bickerstaff's brainstem encephalitis. ",
"Anti-GM1 IgG, GD1a IgG, GQ1b IgG, and GT1a IgG antibodies were positive.",
"The discovery of the association of the anti-GQ1b IgG antibody with the postinfectious clinical syndromes of ophthalmoplegia, ataxia, and areflexia helped house the phenotypes of the Miller Fisher syndrome (MFS), atypical MFS, Guillain-Barré syndrome with ophthalmoplegia, and Bickerstaff's brainstem encephalitis under one roof.

"pregulated miR-146a expression in peripheral blood mononuclear cells from rheumatoid arthritis patients",
"Total RNA was isolated from peripheral blood mononuclear cells obtained from patients with rheumatoid arthritis, and healthy and disease control individuals, and the expression of miR-146a, miR-155, miR-132, miR-16, and microRNA let-7a was analyzed using quantitative real-time PCR",
"Rheumatoid arthritis peripheral blood mononuclear cells exhibited between 1.8-fold and 2.6-fold increases in miR-146a, miR-155, miR-132, and miR-16 expression, whereas let-7a expression was not significantly different compared with healthy control individuals",

515df98f298dcd4e51000030 | yesno | Is Bladder training an effective method to treat urge incontinence ? | [
"Yes. Bladder training is a simple, safe, and effective treatment in the management of mild to moderate forms of urinary incontinence in outpatient populations. It can be used as a first-line treatment or in combination with such other interventions as pelvic muscle exercises, bladder pressure biofeedback, electrical stimulation, and drug therapy. Quoted results vary from 26 to 90% . Patients with sensory urgency appeared to do better than those with detrusor instability and it is suggested that bladder training may be indicated as primary treatment in sensory urgency."
] | [
"yes"
] | [
"Mindfulness-based stress reduction appears to be a treatment worthy of further study, as in the short term, it is as effective as historical studies of drug treatment and bladder training in reducing urge incontinence and incontinence-related quality of life.",
"All patients, irrespective of the results of cystometry were subsequently treated with oxybutynin 2.5 mg twice daily along with bladder training.",
"Of the 29 patients with stable bladder and symptoms of OAB, 100% cure rate was achieved in 20 (68.9%) and 06 (20.6%) patients respectively. While in 3 patients in both groups, decrease of symptoms upto 75% after 6 months of treatment was observed.",
"Both urodynamically proven unstable and stable bladder showed nearly equal improvement with treatment",
"There are 3 types of urine incontinence (urge-, stress-, and overflow-incontinence). Another standardization of urinary incontinence follows dysfunctions of the pelvic floor: detrusor muscle-dependent, due to sphincter spasm, prostate gland dependent. Urge incontinence with a dysfunction of the detrusor muscle is the most common type. Mixed types are frequent. Non-drug measures (e.g. pelvic muscle training, bladder training, toilet training are first choice treatments.",
"Treatment of stress, urge and mixed incontinence can usually be commenced in primary care; pelvic floor exercises and bladder training are preferred. If bladder training is not effective for urge incontinence, anticholinergic drugs should be considered.",
"Sixty patients (age 8 to 12 years) with urge incontinence or dysfunctional voiding were evaluated. After a no-treatment control period (average 6 months), patients underwent a 6-day bladder training course",
"Six months after training completion, 64.1% and 64.7% of the inpatient and outpatient groups with daytime wetting and 51.5% and 17.7% of the inpatient and outpatient groups with nighttime wetting were cured or had improved",
"Of the inpatient group with urge incontinence, the functional bladder capacity increased by 15%.",
"To compare the efficacy of tolterodine plus simplified bladder training (BT) with tolterodine alone in patients with an overactive bladder.",
"CONCLUSIONS: Tolterodine 2 mg twice daily is an effective and well tolerated treatment for an overactive bladder, the effectiveness of which can be augmented by a simplified BT regimen.",
"Bladder training is a modification of bladder drill that is conducted more gradually on an outpatient basis and has resulted in significant reduction of incontinence in older, community-dwelling women.",
"OBJECTIVE: To evaluate the long-term effect of treatment of female incontinence by the general practitioner (pelvic floor exercises, and bladder training) in female urinary incontinence.",
"Stress incontinence and urge incontinence were treated by means of pelvic floor exercises and bladder training respectively, while a mixed incontinence was treated by bladder training followed by pelvic floor exercises. T",
"The treatment consisted of training of pelvic muscles in stress incontinence and bladder training in urge incontinence",
"RESULTS: After 3 months the mean frequency of urine loss per week diminished from 21 to 8, and after 12 months to 6 times.",

It can be used as a first-line treatment or in combination with such other interventions as pelvic muscle exercises, bladder pressure biofeedback, electrical stimulation, and drug therapy",
"Treatment consisted of pelvic floor exercises in the case of stress incontinence and bladder training in the case of urge incontinence.",
"After 3 months about 60% of the patients were either dry or only mildly incontinent",
"terodiline group shows this drug to be a valuable adjunct to a bladder regimen in children with urge incontinence",
"Basing on our experience with 39 patients with severe urge incontinence (in one-quarter of the cases pure urge incontinence, in one-half of the cases mixed incontinence and in a further quarter of the cases neurogenic bladder disorders) a supervised programme (mictiogram) and a well-tried therapy (especially in the Anglo-Saxon countries) consisting of the triad hospitalisation/bladder training/medication therapy are presented. After an average hospitalisation period of 14 days, we were able to achieve a symptom-free state in 94% of the patients.",
"Anamnestic and urodynamical results are evaluated before and after bladder retraining drill (BRD) in women suffering from urge incontinence.",
"We could state that the BRD is a good possibility to realize multistep-therapy of female incontinence.",
"Twenty consecutive female patients with urge incontinence and stable detrusor function on provocative rapid fill CO2-cystometry were treated as out-patients with a bladder training programme and with terodiline/placebo in a double-blind cross-over design.",
"In conclusion, female patients with idiopathic urge incontinence and stable detrusor function did respond to treatment as do female patients with urge incontinence and proven instability.",
"The results of in-patient bladder training in 65 women with frequency, urgency and urge incontinence are reported. There was a good initial response in 88%. By 6 months the response rate had fallen to 38%.",
"Patients with sensory urgency appeared to do better than those with detrusor instability and it is suggested that bladder training may be indicated as primary treatment in sensory urgency.",
"Bladder training and/or biofeedback techniques were used to treat 75 patients with frequency, urgency, nocturia and urge incontinence. Significant improvement or cure was obtained in 70 per cent of enuretic children, and 66 per cent of men and 74 per cent of women with unstable detrusor function."

"The first-line standard therapy for uveitis is topical and systemic corticosteroids, often reinforced by methotrexate as a second-line disease-modifying antirheumatic drug (DMARD). MTX has a topical steroid sparing effect as well. Early treatment with MTX is advocated to prevent complications such as cataract. There are no trial data on the effect of MTX. Most experience among DMARD's/ immunosuppressive drugs has been obtained with methotrexate (MTX) in juvenile idiopathic arthritis. However, controlled studies in uveitis are still missing, so that treatment with MTX and all other immunosuppressive drugs (ciclosporine A, azathioprine, mycophenolate mofetil) only reaches an evidence level III (expert opinion, clinical experience or descriptive study). Biologic DMARDs can be used with Methotrexate in refractory uveitis as well."

"Eighteen patients (18/22; 82%) showed improvement of their uveitis with a significant decrease in activity of AC inflammation after a minimal period of 3 months of MTX treatment. A topical steroid-sparing effect was observed when MTX was administered for a period of 3 to 9 months",
"Most experience among DMARD's/ immunosuppressive drugs has been obtained with methotrexate (MTX) in juvenile idiopathic arthritis. However, controlled studies in uveitis are still missing, so that treatment with MTX and all other immunosuppressive drugs (ciclosporine A, azathioprine, mycophenolate mofetil) only reaches an evidence level III (expert opinion, clinical experience or descriptive study)",
"The data suggest that MTX is very effective in controlling inflammation of uveitis in patients with JIA. However, additional topical steroids or systemic immunosuppressive drugs are often required.",
"The risk factor for development of early cataract requiring surgery in children with JIA-associated uveitis is the presence of posterior synechia at the time of diagnosis of uveitis.

"CRP1, a protein localized in filopodia of growth cones, is involved in dendritic growth",
"CRP1, which cross-links actin filaments to make actin bundles, is the only CRP family member expressed in the CNS with little known about its function in nerve cells.",
"Here, we report that CRP1 colocalizes with actin in the filopodia of growth cones in cultured rat hippocampal neurons.",
"Knockdown of CRP1 expression by short hairpin RNA interference results in inhibition of filopodia formation and dendritic growth in neurons.",
"Overexpression of CRP1 increases filopodia formation and neurite branching, which require its actin-bundling activity.",
"F-ascin is an actin-bundling protein involved in filopodia assembly and cancer invasion and metastasis of multiple epithelial cancer types.",
"In this study, we investigated the role of fascin, a cytoskeleton actin-bundling protein involved in the formation of filopodia and cell migration, in prostate cancer progression.",
"In cellular models, fascin gene silencing using small interfering RNA in the androgen-independent prostate cancer cell line DU145 decreased cell motility and invasiveness while increasing cell adhesive properties.",
"Fascin is an actin-bundling protein that induces membrane protrusions and cell motility after the formation of lamellipodia or filopodia.",
"The PCH family member MAYP/PSTPIP2 directly regulates F-actin bundling and enhances filopodia formation and motility in macrophages",
"Overexpression of MAYP decreased CSF-1-induced membrane ruffling and increased filopodia formation, motility and CSF-1-mediated chemotaxis.",
"The opposite phenotype was observed with reduced expression of MAYP, indicating that MAYP is a negative regulator of CSF-1-induced membrane ruffling and positively regulates formation of filopodia and directional migration.",
"Overexpression of MAYP led to a reduction in total macrophage F-actin content but was associated with increased actin bundling. Consistent with this, purified MAYP bundled F-actin and regulated its turnover in vitro.",
"In addition, MAYP colocalized with cortical and filopodial F-actin in vivo.",
"Because filopodia are postulated to increase directional motility by acting as environmental sensors, the MAYP-stimulated increase in directional movement may be at least partly explained by enhancement of filopodia formation.",
"We report an unexpected direct association between fascin, an actin-bundling component of filopodia, microspikes and lamellipodial ribs, and protein kinase Calpha (PKCalpha), a regulator of focal adhesions.",
"Fascin is an actin-bundling protein involved in filopodia assembly and cancer invasion and metastasis of multiple epithelial cancer types.",
"Actin-crosslinking proteins organize actin into highly dynamic and architecturally diverse subcellular scaffolds that orchestrate a variety of mechanical processes, including lamellipodial and filopodial protrusions in motile cells.",
"IRSp53, a multi-domain protein that can associate with the Rho-GTPases Rac and Cdc42, participates in these processes mainly through its amino-terminal IMD (IRSp53 and MIM domain). The isolated IMD has actin-bundling activity in vitro and is sufficient to induce filopodia in vivo.",
"Eps8 activates and synergizes with IRSp53 in mediating actin bundling in vitro, enhancing IRSp53-dependent membrane extensions in vivo.",
"Consistently, Cdc42-induced filopodia are inhibited following individual removal of either IRSp53 or Eps8.",
"Collectively, these results support a model whereby the synergic bundling activity of the IRSp53-Eps8 complex, regulated by Cdc42, contributes to the generation of actin bundles, thus promoting filopodial protrusions.",
"The bundling activity of vasodilator-stimulated phosphoprotein is required for filopodium formation",
"Filopodia are highly dynamic finger-like cell protrusions filled with parallel bundles of actin filaments. Previously we have shown that Diaphanous-related formin dDia2 is involved in the formation of filopodia. Another key player for the formation of filopodia across many species is vasodilator-stimulated phosphoprotein (VASP).",
"It has been proposed that the essential role of VASP for formation of filopodia is its competition with capping proteins for filament barbed-end interaction.",
"Only WT DdVASP, but not a mutant lacking the F-actin bundling activity, could rescue the ability of these cells to form WT-like filopodia.",
"Our data suggest that DdVASP is complexed with dDia2 in filopodial tips and support formin-mediated filament elongation by bundling nascent actin filaments.",
"Insulin receptor tyrosine kinase substrate p53 (IRSp53) has been identified as an SH3 domain-containing adaptor that links Rac1 with a Wiskott-Aldrich syndrome family verprolin-homologous protein 2 (WAVE2) to induce lamellipodia or Cdc42 with Mena to induce filopodia.",
"Here, we show that the N-terminal predicted helical stretch of 250 amino acids of IRSp53 is an evolutionarily conserved F-actin bundling domain involved in filopodium formation.",
"The IMD alone, derived from either IRSp53 or MIM, induced filopodia in HeLa cells and the formation of tightly packed parallel F-actin bundles in vitro.",
"These results suggest that IRSp53 and MIM belong to a novel actin bundling protein family.",
"Role of the actin bundling protein fascin in growth cone morphogenesis: localization in filopodia and lamellipodia",
"Fascin localized to radially oriented actin bundles in lamellipodia (ribs) and filopodia.",
"Using a fascin antibody and a GFP fascin construct, we found that fascin incorporated into actin bundles from the beginning of growth cone formation at the cut end of axons.",
"Later, during growth cone morphogenesis when actin ribs shortened, the proximal fascin-free zone of bundles increased, but fascin was retained in the distal, filopodial portion of bundles.",
"Treatment with tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA), which phosphorylates fascin and decreases its affinity for actin, resulted in loss of all actin bundles from growth cones.",
"Our findings suggest that fascin may be particularly important for the linear structure and dynamics of filopodia and for lamellipodial rib dynamics by regulating filament organization in bundles."

"Finally, Tsc1(-/-) mouse embryonic fibroblasts (MEFs) have increased number of centrosomes and increased DNA content, compared to Tsc1(+/+) cells.",
"Both phenotypes are rescued after pre-treatment with the mTOR inhibitor rapamycin. RNAi inhibition of Plk1 in Tsc1(-/-) MEFs failed to rescue the increased centrosome number phenotype. These data reveal a novel subcellular localization for hamartin and a novel interaction partner for the hamartin/tuberin complex and implicate hamartin and mTOR in the regulation of centrosome duplication."

"LepChorionDB, a database of Lepidopteran chorion proteins and a set of tools useful for the identification of chorion proteins in Lepidopteran proteomes",
"A database, named LepChorionDB, was constructed by searching 5 different protein databases using class A and B central domain-specific profile Hidden Markov Models (pHMMs), developed in this work. A total of 413 Lepidopteran chorion proteins from 9 moths and 1 butterfly species were retrieved. These data were enriched and organised in order to populate LepChorionDB, the first relational database, available on the web, containing Lepidopteran chorion proteins grouped in A and B classes. LepChorionDB may provide insights in future functional and evolutionary studies of Lepidopteran chorion proteins and thus, it will be a useful tool for the Lepidopteran scientific community and Lepidopteran genome annotators, since it also provides access to the two pHMMs developed in this work, which may be used to discriminate A and B class chorion proteins",

"To analyze whether the time (morning/evening) of administration of a compound containing 60 mg of dry soy seed extract (glycine max) with 40% of total isoflavones, primrose oil and α-tocopherol modifies the effect on the climacteric syndrome.",
"The object of this study was to evaluate the effect of different doses of a compound containing isoflavones 60 mg, primrose oil 440 mg and vitamin E 10 mg. (IOVE) on menopausal complaints. This was an open, multicentre, randomised, group comparative, efficacy and safety trial.",
"Emphasis was placed on randomized, double-blind, placebo-controlled clinical trials, as these provide the best efficacy and safety data",
"Nonprescription therapies reviewed include black cohosh, dong quai, evening primrose oil, physical activity, phytoestrogens, and red clover",

"These results show that 1) SLN regulates Ca(2+)-ATPase activity thereby regulating contractile kinetics in at least some skeletal muscles, 2) the functional significance of SLN is graded to the endogenous SLN expression level, and 3) SLN inhibitory effects on SERCA function are relieved in response to repeated contractions thus enhancing relaxation rates.",
"The SERCA pump was constitutively activated in both atrial and ventricular chambers of the mouse heart by ablating its key regulators, phospholamban (PLN) and sarcolipin (SLN). The double-knockout (dKO) mice for PLN and SLN showed increased SERCA pump activity, Ca(2+) transients and SR Ca(2+) load, and developed cardiac hypertrophy.",
"Our findings also emphasize the need for dynamic regulation of the SERCA pump by PLN and/or SLN to maintain cardiac contractility in normal conditions and during pathophysiological states.",
"Sarcolipin (SLN) has emerged as an important regulator of the atrial sarcoplasmic reticulum (SR) Ca2+ transport.",
"The inhibitory effect of SLN on cardiac SR Ca2+ ATPase (SERCA) pump can be relieved by beta-adrenergic stimulation, which indicates that SLN is a reversible inhibitor. ",
"Sarcolipin is a novel regulator of cardiac sarcoplasmic reticulum Ca2+ ATPase 2a (SERCA2a) and is expressed abundantly in atria.",
"Our study documented that sarcolipin is a key regulator of SERCA2a in atria. Importantly, our data demonstrate the existence of distinct modulators for the SERCA pump in the atria and ventricles.",
"Sarcoplasmic reticulum (SR) Ca(2+) ATPase (SERCA) is a membrane protein that catalyzes the ATP-dependent transport of Ca(2+) from the cytosol to the SR. The activity of SERCA is inhibited by phospholamban (PLN) and sarcolipin (SLN), and all these proteins participate in maintaining the normal intracellular calcium handling. ",
"Sarcolipin (SLN) is an integral membrane protein that is expressed in both skeletal and cardiac muscle, where it inhibits SERCA (calcium ATPase) by lowering its apparent Ca2+ affinity in a manner similar to that of its homologue phospholamban (PLN).",
"Remarkably, each domain of SLN behaves in a manner similar to that of the corresponding domains in PLN, supporting the hypothesis that both SLN and PLN bind SERCA in the same groove and with similar mechanisms.",
"The role of sarcolipin (SLN) in cardiac physiology was critically evaluated by generating a transgenic (TG) mouse model in which the SLN to sarco(endoplasmic)reticulum (SR) Ca(2+) ATPase (SERCA) ratio was increased in the ventricle. Overexpression of SLN decreases SR calcium transport function and results in decreased calcium transient amplitude and rate of relaxation. SLN TG hearts exhibit a significant decrease in rates of contraction and relaxation when assessed by ex vivo work-performing heart preparations.",
"We conclude that SLN is a novel regulator of SERCA pump activity, and its inhibitory effect can be reversed by beta-adrenergic agonists.",
"Sarcolipin, a homologue of phospholamban, regulates Ca2+ uptake through the interaction with sarcoplasmic reticulum Ca2+ ATPase (SERCA) and is predominantly expressed in the atrial muscle.",
"Sarcolipin (SLN) and phospholamban (PLN) are effective inhibitors of the sarco(endo)plasmic reticulum Ca(2+)-ATPase (SERCA). ",
"These results show that NF-SLN expression impairs muscle contractile function by inhibiting SERCA function and diminishing sarcoplasmic reticulum Ca(2+) stores.",
"Sarcolipin (SLN) is an inhibitor of sarco(endo)plasmic reticulum Ca(2+)-ATPases (SERCAs) in vitro, but its function in vivo has not been defined. NF-SLN cDNA (SLN tagged N-terminally with a FLAG epitope) was introduced into rat soleus muscle in one hindlimb by plasmid injection and electrotransfer.",
"Sarcolipin (SLN), a regulator of the sarco(endo)plasmic reticulum Ca(2+)-ATPase of fast-twitch skeletal muscle (SERCA1a), is also expressed in cardiac and slow-twitch skeletal muscles where phospholamban (PLN) and SERCA2a are expressed.",
"Sarco(endo)plasmic reticulum calcium ATPase (SERCA) inhibition by sarcolipin is encoded in its luminal tail.",
"The sarco(endo)plasmic reticulum calcium ATPase (SERCA) is regulated in a tissue-dependent manner via interaction with the short integral membrane proteins phospholamban (PLN) and sarcolipin (SLN).",
"Phospholamban (PLN) and sarcolipin (SLN) are two single-pass membrane proteins that regulate Ca2+-ATPase (SERCA), an ATP-driven pump that translocates calcium ions into the lumen of the sarcoplasmic reticulum, initiating muscle relaxation.",
"The sarco(endo)plasmic reticulum calcium ATPase (SERCA) is regulated in a tissue-dependent manner via interaction with the short integral membrane proteins phospholamban (PLN) and sarcolipin (SLN)",

5507ea9a0195c16935000008 | summary | What type of arrhythmia is known as bidirectional ventricular tachycardia (BDVT)? | [
"Bidirectional ventricular tachycardia (BVT), which is characterized by an alternating beat-to-beat ECG QRS axis, is a rare but intriguing arrhythmia associated with digitalis toxicity, familial catecholaminergic polymorphic ventricular tachycardia (CPVT), and several other conditions that predispose cardiac myocytes to delayed afterdepolarizations (DADs) and triggered activity. Bidirectional ventricular tachycardia (BVT) is an uncommon type of polymorphic ventricular tachycardia (PVT). Based on similarity of electrocardiographic features, bidirectional ventricular tachycardia has been considered a variant of long QT syndrome. Evidence from human and animal studies attributes BVT to alternating ectopic foci originating from the distal His-Purkinje system in the left and/or right ventricle, respectively. This \"ping pong\" mechanism of reciprocating bigeminy readily produces the characteristic ECG pattern of BVT and its degeneration to polymorphic VT if additional sites develop bigeminy."

Evidence from human and animal studies attributes BVT to alternating ectopic foci originating from the distal His-Purkinje system in the left and/or right ventricle, respectively.",
"When the heart rate exceeded the threshold for bigeminy at the first site in the His-Purkinje system, ventricular bigeminy developed, causing the heart rate to accelerate and exceed the threshold for bigeminy at the second site. Thus, the triggered beat from the first site induced a triggered beat from the second site. The triggered beat from the second site next reciprocated by inducing a triggered beat from the first site, and so forth. Bigeminy from two sites produced BVT, and that from three or more sites produced polymorphic VT.",
"This \"ping pong\" mechanism of reciprocating bigeminy readily produces the characteristic ECG pattern of BVT and its degeneration to polymorphic VT if additional sites develop bigeminy.",
"The BVT, in this case, was most likely due to myocardial ischema. The ethiology of published BVT cases are most commonly digitalis toxicity and rarely herbal aconitine poisoning, hypokalemic periodic paralysis, cathecolaminergic VT, myocarditis, and Anderson-Tawil syndrome.",
"Bidirectional ventricular tachycardia (BVT), although a rare arrhythmia in the general population, is frequently observed in patients with Andersen-Tawil syndrome and long QT interval. However, the pharmacologic treatment of this arrhythmia remains unknown.",
"This report suggests that flecainide can be effective in controlling BVT associated with Andersen-Tawil syndrome and indicates that the left ventricular dysfunction is secondary to the arrhythmia and not due to an associated phenotypic manifestation of the disorder.",
"Based on similarity of electrocardiographic features, bidirectional ventricular tachycardia has been considered a variant of long QT syndrome.",
"Double ventricular ectopic rhythms had bizarre abnormal QRS complexes of two different morphologies and were inscribed in opposite directions. Ectopic rhythms in each case had parasystolic characteristics. These observations suggest bifocal automaticity as a mechanism for bidirectional ventricular tachycardia.",
"Bidirectional ventricular tachycardia, defined as the rapid alternation of the QRS complexes with successive opposing axial deviation, is a rare arrhythmia. In the rare cases which have undergone endocavitary investigations, an infrahisian origin has generally been proved. However, the mechanism of these tachycardias remains poorly understood and is discussed with respect to a new case.",
"In the light of previously reported cases with documented endocavitary investigation and this new case, it seems possible to talk in terms of true \"bidirectional ventricular tachycardia\", a tachycardia whose mechanism is obscure but certainly not univocal.",

"Yes, mutations in CALM underly IVF manifesting in childhood and adolescence."
] | [
"yes"
] | [
"We characterized a family presenting with a history of ventricular fibrillation (VF) and sudden death without ECG or echocardiographic abnormalities at rest. Two siblings died suddenly at the ages of 9 and 10 years, and another two were resuscitated from out-of-hospital cardiac arrest with documented VF at age 10 and 16, respectively. Exome sequencing identified a missense mutation affecting a highly conserved residue (p.Phe90Leu) in the CALM1 gene encoding calmodulin. This mutation was also carried by one of the sibs who died suddenly, for whom DNA was available. The mutation was present in the mother and in an sibling, both asymptomatic but displaying a marginally prolonged QT-interval during exercise. CONCLUSIONS: We identified a mutation in CALM1 underlying IVF manifesting in childhood and adolescence. The causality of the mutation is supported by previous studies demonstrating that Phe90 mediates the direct interaction of CaM with target peptides",
"Here we show that calmodulin (CaM), a ubiquitous Ca2+-sensing protein, binds to the carboxy-terminal 'IQ' domain of the human cardiac Na channel (hH1) in a Ca2+-dependent manner. This binding interaction significantly enhances slow inactivation-a channel-gating process linked to life-threatening idiopathic ventricular arrhythmias. Mutations targeted to the IQ domain disrupted CaM binding and eliminated Ca2+/CaM-dependent slow inactivation, whereas the gating effects of Ca2+/CaM were restored by intracellular application of a peptide modelled after the IQ domain.

"Compared with Sleeping Beauty, PiggyBac exhibits higher transposition efficiencies, no evidence for local hopping and a significant bias toward reintegration in intragenic regions, which demonstrate its utility for insertional mutagenesis. ",
"We found that PB demonstrated the highest efficiency of stable gene transfer in PBL-derived T cells, whereas SB11 and Tol2 mediated intermediate and lowest efficiencies, respectively. ",
"However, recently another system known as PiggyBac (PB) has been introduced and developed for fulfilling the same purposes, for example, mutagenesis, transgenesis and gene therapy and in some cases with improved transposition efficiency and advantages over the Sleeping Beauty transposon system, although improved hyperactive transposase has highly increased the transposition efficacy for SB. ",

"Compared with Sleeping Beauty, PiggyBac exhibits higher transposition efficiencies, no evidence for local hopping and a significant bias toward reintegration in intragenic regions, which demonstrate its utility for insertional mutagenesis.",
"In this study, we compared the genomic integration efficiencies and transposition site preferences of Sleeping Beauty (SB or SB11), Tol2, and piggyBac (PB) transposon systems in primary T cells derived from peripheral blood lymphocytes (PBL) and umbilical cord blood (UCB). We found that PB demonstrated the highest efficiency of stable gene transfer in PBL-derived T cells, whereas SB11 and Tol2 mediated intermediate and lowest efficiencies, respectively. ",
"Compared with Sleeping Beauty, PiggyBac exhibits higher transposition efficiencies, no evidence for local hopping and a significant bias toward reintegration in intragenic regions, which demonstrate its utility for insertional mutagenesis. Although Sleeping Beauty had no detectable genomic bias with respect to insertions in genes or intergenic regions, both Sleeping Beauty and PiggyBac transposons displayed preferential integration into actively transcribed loci.",
"We have compared the chromosomal mobilization efficiency and insertion site preference of the two transposons mobilized from the same donor site in mouse embryonic stem (ES) cells under conditions in which there were no selective constraints on the transposons' insertion sites. Compared with Sleeping Beauty, PiggyBac exhibits higher transposition efficiencies, no evidence for local hopping and a significant bias toward reintegration in intragenic regions, which demonstrate its utility for insertional mutagenesis.",
"In this study we directly compared the genomic integration efficiencies of piggyBac, hyperactive Sleeping Beauty (SB11), Tol2, and Mos1 in four mammalian cell lines. piggyBac demonstrated significantly higher transposition activity in all cell lines whereas Mos1 had no activity."

"rivaroxaban undergoes renal metabolism"
] | [
"yes"
] | [
"The novel oral anticoagulants (i.e., dabigatran, apixaban, rivaroxaban) all undergo renal metabolism to varying degrees, and hence dosing, efficacy, and safety require special consideration in CKD patients.",
"The new oral anticoagulants have relatively little data in patients with severe renal impairment, and all have an element of renal excretion.",
"Now new anticoagulant drugs(dabigatran and rivaroxaban) can become available. Therefore, we have to learn how to use those drugs. They have to carefully be used because they discharge from kidney and old aged patients have potential renal dysfunction. ",
"In the everyday practice it will be necessary to be very cautious in patients with impaired renal function, as all these drugs are eliminated by kidneys.",
"Dabigatran etexilate and rivaroxaban carry the highest risk due to a high degree of renal excretion, whereas the risk for apixaban, edoxaban and betrixaban seems lower.",
"However, all these agents undergo renal clearance to varying degrees, and hence dosing, efficacy, and safety require special consideration in patients with CKD. ",
"Rivaroxaban being excreted via kidney and liver, some precautions should apply in case of liver insufficiency. ",
"Rivaroxaban elimination is mainly renal, but also through faecal matter and by hepatic metabolism. "

"Side effects of nalmefene include nausea, dizziness / lightheadedness, insomina, fatigue, vomiting, reduced caloric intake / apetite, increased self-rated alertness and decreased tiredness.

"Adverse experiences included nausea, dizziness, and insomnia.",
"Side effects to nalmefene were of greater duration and intensity in the subjects receiving 10 mg of nalmefene vs. those receiving 6 or 2 mg. These included most notably fatigue, lightheadedness, nausea and vomiting.",
"The nalmefene treated group ate 22% less, both in terms of absolute weight and caloric intake, of a standardised buffet-meal than did the placebo group. ",
"Thus the apparent nutrient specificity of nalmefene appeared to be an indirect consequence of its effect on palatability. Nalmefene also caused slight increases in self-rated alertness, and decreases in ratings of tiredness and elation, although it was thought unlikely that these accounted for observed changes in eating behaviour.",
"In the second study, six healthy men were initially administered a single 50-mg dose of drug, and plasma samples were obtained at selected time intervals for 48 hours. A dosing schedule of 20 mg q12h was then started and continued for seven days. Plasma samples were collected immediately before each dose and at selected times for up to 48 hours after the last dose. The drug was well tolerated by all subjects, and no clinically significant adverse effects were observed during the seven-day administration period.",
" In the first study, single ascending doses of 50, 100, 200, and 300 mg of nalmefene HCl were administered in double-blind fashion to four groups of healthy men. There were six subjects in each group; four received nalmefene and two received placebo. The drug was well tolerated at all dose levels with only mild and transient side effects, such as lightheadedness, at the higher doses. ",
"Doses of nalmefene as large as 0.4 mg/kg, IV, produced only minor side effects. These side effects included some passage of semifluid fecal material, intermittent penile relaxation, and mild sedation. Treated horses responded normally to external stimuli, retained their appetites, and performed appropriately when ridden. Sedation wore off during the course of prolonged infusions. ",
"The drug was well tolerated at all dose levels with only mild and transient side effects, the most common of which was lightheadedness."

"Ultraconserved elements and their flanking DNA are novel phylogenomic markers that resolve placental mammal phylogeny when combined with species-tree analysis. Because orthologous UCEs can be obtained from a wide array of taxa, are polymorphic at shallow evolutionary timescales, and can be generated rapidly at low cost, they are an effective genetic marker for studies investigating evolutionary patterns and processes at shallow timescales."

"Target capture and massively parallel sequencing of ultraconserved elements for comparative studies at shallow evolutionary time scales",
"Here, we evaluate the efficacy of genomic markers targeting ultraconserved DNA elements (UCEs) for analyses at shallow evolutionary timescales",
"Because orthologous UCEs can be obtained from a wide array of taxa, are polymorphic at shallow evolutionary timescales, and can be generated rapidly at low cost, they are an effective genetic marker for studies investigating evolutionary patterns and processes at shallow timescales",
"A Phylogenomic Perspective on the Radiation of Ray-Finned Fishes Based upon Targeted Sequencing of Ultraconserved Elements (UCEs)",
"Here, we provide a genomic perspective on longstanding questions regarding the diversification of major groups of ray-finned fishes through targeted enrichment of ultraconserved nuclear DNA elements (UCEs) and their flanking sequence. Our workflow efficiently and economically generates data sets that are orders of magnitude larger than those produced by traditional approaches and is well-suited to working with museum specimens. Analysis of the UCE data set recovers a well-supported phylogeny at both shallow and deep time-scales that supports a monophyletic relationship between Amia and Lepisosteus (Holostei) and reveals elopomorphs and then osteoglossomorphs to be the earliest diverging teleost lineages. Our approach additionally reveals that sequence capture of UCE regions and their flanking sequence offers enormous potential for resolving phylogenetic relationships within ray-finned fishes",
"We applied a new phylogenomic approach to resolve relationships in Neoaves using target enrichment (sequence capture) and high-throughput sequencing of ultraconserved elements (UCEs) in avian genomes. We collected sequence data from UCE loci for 32 members of Neoaves and one outgroup (chicken) and analyzed data sets that differed in their amount of missing data",
"More than 1000 ultraconserved elements provide evidence that turtles are the sister group of archosaurs",
"A recent analysis of shared microRNA families found that turtles are more closely related to lepidosaurs. To test this hypothesis with data from many single-copy nuclear loci dispersed throughout the genome, we used sequence capture, high-throughput sequencing and published genomes to obtain sequences from 1145 ultraconserved elements (UCEs) and their variable flanking DNA. The resulting phylogeny provides overwhelming support for the hypothesis that turtles evolved from a common ancestor of birds and crocodilians, rejecting the hypothesized relationship between turtles and lepidosaurs",
"Ultraconserved elements anchor thousands of genetic markers spanning multiple evolutionary timescales",
"We introduce a new class of molecular marker, anchored by ultraconserved genomic elements (UCEs), that universally enable target enrichment and sequencing of thousands of orthologous loci across species separated by hundreds of millions of years of evolution. Our analyses here focus on use of UCE markers in Amniota because UCEs and phylogenetic relationships are well-known in some amniotes. We perform an in silico experiment to demonstrate that sequence flanking 2030 UCEs contains information sufficient to enable unambiguous recovery of the established primate phylogeny.

". Loss-of-function truncation mutations in EMD, encoding the nuclear membrane protein emerin, cause X-linked Emery-Dreifuss muscular dystrophy (EDMD) characterized by localized contractures and skeletal myopathy in adolescence, sinus node dysfunction (SND) in early adulthood, and atrial fibrillation as a variably associated trait.",
"Mutation of EMD can underlie X-linked familial AF. Lys37del is associated with epithelial cell emerin deficiency, as in EDMD, yet it causes electrical atriomyopathy in the absence of skeletal muscle disease. Targeted genetic testing of EMD should be considered in patients with SND-associated AF and/or family history suggesting X-linked inheritance.",
"The Emery-Dreifuss muscular dystrophy is a form of muscular dystrophy that frequently presents early contractures and cardiac conduction defects, caused by emerin deficiency in the inner nuclear membrane of the muscular fibers.",
"compatible with X-linked inheritance form",
"The first patient was a member of a family with molecularly proven X-linked EDMD.",
"As these resemble the cardiac features of patients with the autosomal dominant variant of EDMD, we examined the lamin A/C gene, identifying a de-novo mutation in the propositus.",
"contribute to disease severity in autosomal dominant EDMD.",
"The STA gene encodes emerin and is one of the genes that is affected in Emery-Dreifuss muscular dystrophy (EDMD). Although it has been reported that EDMD caused by the STA gene mutation is associated with X-linked recessive inheritance, the genotype-phenotype correlations, with special reference to cardiac manifestations, are not well defined.",
"Emery-Dreifuss muscular dystrophy (EDMD) is a muscular disorder characterized by 1) early contracture of the elbows. Achilles tendons and post-cervical muscles, 2) slowly progressive muscle wasting and weakness with a humeroperoneal distribution, and 3) life-threatening cardiomyopathy with conduction block. Most of families with EDMD show X-linked recessive inheritance with mutations in the STA gene on chromosome Xq28, which encodes a protein named emerin. A rare autosomal dominant form of EDMD (AD-EDMD) is caused by mutations in lamin A/C gene (LMNA) on chromosome 1q21. Both emerin and lamin A/C are located in the inner surface membrane of the nucleus.",
"Emery-Dreifuss muscular dystrophy is an X-linked recessive myopathy. The patient had no familial background of the disease. This patient might have a sporadic inheritance pattern with severe cardiac involvement.",
"autosomal dominant Emery-Dreifuss muscular dystrophy,",
"Emery-Dreifuss muscular dystrophy is characterized by the clinical triad of early onset contractures of elbows, Achilles tendons and spine, wasting and weakness with a predominantly humero-peroneal distribution and life-threatening cardiac conduction defects and/or cardiomyopathy. Two main types of inheritance have been described: the X-linked form is caused by mutations in the STA gene on locus Xq28 and the gene for the autosomal dominant form (LMNA gene) has been localized on chromosome 1q11-q23. Recently, mutations in this LMNA gene have been also found to be responsible for the less frequent autosomal recessive form of the disease.",
"Emery-Dreifuss muscular dystrophy (EDMD) is characterized by early contractures of elbows and Achilles tendons, slowly progressive muscle wasting and weakness, and a cardiomyopathy with conduction blocks which is life-threatening. Two modes of inheritance exist, X-linked (OMIM 310300) and autosomal dominant (EDMD-AD; OMIM 181350). EDMD-AD is clinically identical to the X-linked forms of the disease. Mutations in EMD, the gene encoding emerin, are responsible for the X-linked form.",
"including X-linked Emery-Dreifuss MD,",
"this form is not X-linked Emery-Dreifuss MD. We suggest that these patients represent a severe MD characterized by early onset distal wasting and severe rigidity of the spine, with probable autosomal recessive inheritance.",
"Seventeen families with Emery-Dreifuss muscular dystrophy (EDMD) have been studied both by DNA sequencing and by emerin protein expression. Fourteen had mutations in the X-linked emerin gene, while three showed evidence of autosomal inheritance. Twelve of the 14 emerin mutations caused early termination of translation.",
"One family presented a rare autosomal dominant variant of Emery-Dreifuss muscular dystrophy, another with X-linked recessive inheritance showed unusual intrafamilial variability.",
"Emery-Dreifuss muscular dystrophy (EMD) is characterised by (1) early contractures of the Achilles tendons, elbows, and postcervical muscles, (2) slowly progressive muscle wasting and weakness with a predominantly humeroperoneal distribution in the early stages, and (3) cardiomyopathy with conduction defects and risk of sudden death. Inheritance is usually X linked recessive but can be autosomal dominant.",
"Tendon contractures may be a partial expression of this myopathic disorder, suggesting an autosomal dominant inheritance with variable penetrance. A muscular dystrophy clinically similar to that of the Emery-Dreifuss (EDMD) type can thus occur in women.",
"Since the disease was diagnosed in 3 brothers, the X-coupled recessive type of its inheritance is assumed. An opinion is advanced that the described form is a clinical variety of Emery-Dreyfus myodystrophy.",
"Emery-Dreifuss syndrome (EDS)",
"the term Emery-Dreifuss muscular dystrophy should be avoided. Instead, each case of EDS should be classified as myopathic or neurogenic with X chromosome recessive or autosomal dominant inheritance.",
"Emery-Dreifuss muscular dystrophy is a syndrome with five salient features: early and unusual contractures; humeroperoneal muscle wasting; the slow progression of weakness, beginning in childhood; cardiac conduction defects; and X-linked inheritance. We present two cases and detail other reports with a similar constellation of findings with apparent autosomal dominant inheritance.",
"Emery-Dreifuss muscular dystrophy with proximal weakness in both the upper and lower limbs and X-linked scapuloperoneal muscular dystrophy represent the same disorder.",
"There is at least one other report of autosomal dominant transmission of this clinical picture, which had previously only been reported as Emery-Dreifuss muscular dystrophy with X-linked recessive inheritance."

Our method integrates a novel feature in transmembrane protein topology prediction, which results in improved performance for topology prediction and reliable prediction of phosphorylation and glycosylation sites. The method is freely available at http://bioinformatics.biol.uoa.gr/HMMpTM",
"MetaTM - a consensus method for transmembrane protein topology prediction.",
"A novel TM consensus method, named MetaTM, is proposed in this work. MetaTM is based on support vector machine models and combines the results of six TM topology predictors and two signal peptide predictors. On a large data set comprising 1460 sequences of TM proteins with known topologies and 2362 globular protein sequences it correctly predicts 86.7% of all topologies. CONCLUSION: Combining several TM predictors in a consensus prediction framework improves overall accuracy compared to any of the individual methods. Our proposed SVM-based system also has higher accuracy than a previous consensus predictor. MetaTM is made available both as downloadable source code and as DAS server at http://MetaTM.sbc.su.se",
"We present a support vector machine-based (SVM) TM protein topology predictor that integrates both signal peptide and re-entrant helix prediction, benchmarked with full cross-validation on a novel data set of 131 sequences with known crystal structures. The method achieves topology prediction accuracy of 89%, while signal peptides and re-entrant helices are predicted with 93% and 44% accuracy respectively. An additional SVM trained to discriminate between globular and TM proteins detected zero false positives, with a low false negative rate of 0.4%. We present the results of applying these tools to a number of complete genomes. Source code, data sets and a web server are freely available from http://bioinf.cs.ucl.ac.uk/psipred/",
"Hidden Markov models (HMMs) have been successfully applied to the tasks of transmembrane protein topology prediction and signal peptide prediction. In this paper we expand upon this work by making use of the more powerful class of dynamic Bayesian networks (DBNs). Our model, Philius, is inspired by a previously published HMM, Phobius, and combines a signal peptide submodel with a transmembrane submodel. We introduce a two-stage DBN decoder that combines the power of posterior decoding with the grammar constraints of Viterbi-style decoding. Philius also provides protein type, segment, and topology confidence metrics to aid in the interpretation of the predictions",
"We report a relative improvement of 13% over Phobius in full-topology prediction accuracy on transmembrane proteins, and a sensitivity and specificity of 0.96 in detecting signal peptides",
"HMM_RA: an improved method for alpha-helical transmembrane protein topology prediction",
"This paper presents a Hidden Markov Model (referred to as HMM_RA) that can predict the topology of alpha-helical transmembrane proteins with improved performance. HMM_RA adopts the same structure as the HMMTOP method, which has five modules: inside loop, inside helix tail, membrane helix, outside helix tail and outside loop. Each module consists of one or multiple states",
"A new method (MEMSAT3) for predicting transmembrane protein topology from sequence profiles is described and benchmarked with full cross-validation on a standard data set of 184 transmembrane proteins",
"The algorithms presented here, are easily implemented in any kind of a Hidden Markov Model, whereas the prediction method (HMM-TM) is freely available for academic users",
"TMHMM, the current state-of-the-art method, has less than 52% accuracy in topology prediction on one set of transmembrane proteins of known topology. Based on the observation that there are functional domains that occur preferentially internal or external to the membrane, we have extended the model of TMHMM to incorporate functional domains, using a probabilistic approach originally developed for computational gene finding. Our extension is better than TMHMM in predicting the topology of transmembrane proteins. As prediction of functional domain improves, our system's prediction accuracy will likely improve as well",
"Here, we present Phobius, a combined transmembrane protein topology and signal peptide predictor. The predictor is based on a hidden Markov model (HMM) that models the different sequence regions of a signal peptide and the different regions of a transmembrane protein in a series of interconnected states. Training was done on a newly assembled and curated dataset. Compared to TMHMM and SignalP, errors coming from cross-prediction between transmembrane segments and signal peptides were reduced substantially by Phobius. False classifications of signal peptides were reduced from 26.1% to 3.9% and false classifications of transmembrane helices were reduced from 19.0% to 7.7%. Phobius was applied to the proteomes of Homo sapiens and Escherichia coli. Here we also noted a drastic reduction of false classifications compared to TMHMM/SignalP, suggesting that Phobius is well suited for whole-genome annotation of signal peptides and transmembrane regions",

"Yes, induction of alpha-tubulin acetylation correlates with inhibition of cell motility, while it is involved in additional cellular processes, e.g. cell cycle progression, differentiation, intracellular trafficking, and signalling. Dynamic microtubule (MT) acetylation/deacetylation mediating cell motility and adhesion is controlled by enzymes such as HDAC6, a major cytoplasmic α-tubulin deacetylase. While its overexpression and activation is capable to enhance cell motility, HDAC6 activity can also be negatively regulated by a number of cellular inhibitors, thus decreasing the ability of cells for migration."
] | [
"yes"
] | [
"In this study, we found that paclitaxel induced tubulin acetylation in endothelial and tumor cells, at concentrations that affected cell motility but not proliferation (10(-8) to 10(-9) M, for 4 hours). Induction of tubulin acetylation correlated with inhibition of motility but not proliferation based on a comparison of highly and poorly cytotoxic taxanes (paclitaxel and IDN5390) and tumor cell lines sensitive and resistant to paclitaxel (1A9 and 1A9 PTX22).",
"we found that overexpression of the tubulin deacetylase SIRT2 increased cell motility and reduced cell response to the anti-motility activity of paclitaxel. Conversely, the SIRT2 inhibitor splitomicin reduced cell motility and potentiated the anti-motility activity of paclitaxel. The inhibitory effect was further potentiated by the addition of the HDAC6 inhibitor trichostatin A.",
"Cell motility and adhesion involves dynamic microtubule (MT) acetylation/deacetylation, a process regulated by enzymes as HDAC6, a major cytoplasmic α-tubulin deacetylase.",
"GRK2 and HDAC6 colocalize in the lamellipodia of migrating cells, leading to local tubulin deacetylation and enhanced motility.",
"This review highlights the emerging roles of tubulin acetylation in multiple cellular functions, ranging from cell motility, cell cycle progression or cell differentiation to intracellular trafficking and signalling.",
"Our results indicate that TPPP/p25 binds to HDAC6 (histone deacetylase 6), an enzyme responsible for tubulin deacetylation. Moreover, we demonstrated that the direct interaction of these two proteins resulted in the inhibition of the deacetylase activity of HDAC6.",
"Finally, we demonstrated that, similarly to other HDAC6 inhibitors, TPPP/p25 influences the microtubule dynamics by decreasing the growth velocity of the microtubule plus ends and also affects cell motility as demonstrated by time lapse video experiments.",
"\"tubacin,\" which inhibits alpha-tubulin deacetylation in mammalian cells.",
"We provide evidence that class II histone deacetylase 6 (HDAC6) is the intracellular target of tubacin.",
"Tubacin treatment did not affect the stability of microtubules but did decrease cell motility.",
"They also suggest that small molecules that selectively inhibit HDAC6-mediated alpha-tubulin deacetylation, a first example of which is tubacin, might have therapeutic applications as antimetastatic and antiangiogenic agents.",
"Furthermore, overexpression of HDAC6 promotes chemotactic cell movement, supporting the idea that HDAC6-mediated deacetylation regulates microtubule-dependent cell motility.",
"HDAC6 is a major cytoplasmic a-tubulin deacetylase that is involved in cell motility and adhesion. GRK2 dynamically and directly associates with and phosphorylates HDAC6 to stimulate its a-tubulin deacetylase activity at specific cellular localizations, such as the leading edge of migrating cells, thus promoting local tubulin deacetylation and enhanced motility."

"Flybow: genetic multicolor cell labeling for neural circuit analysis in Drosophila melanogaster.",
"To facilitate studies of neural network architecture and formation, we generated three Drosophila melanogaster variants of the mouse Brainbow-2 system, called Flybow. Sequences encoding different membrane-tethered fluorescent proteins were arranged in pairs within cassettes flanked by recombination sites. Flybow combines the Gal4-upstream activating sequence binary system to regulate transgene expression and an inducible modified Flp-FRT system to drive inversions and excisions of cassettes. This provides spatial and temporal control over the stochastic expression of one of two or four reporters within one sample. Using the visual system, the embryonic nervous system and the wing imaginal disc, we show that Flybow in conjunction with specific Gal4 drivers can be used to visualize cell morphology with high resolution. Finally, we demonstrate that this labeling approach is compatible with available Flp-FRT-based techniques, such as mosaic analysis with a repressible cell marker; this could further support the genetic analysis of neural circuit assembly and function.",
"Drosophila Brainbow: a recombinase-based fluorescence labeling technique to subdivide neural expression patterns.",
"We developed a multicolor neuron labeling technique in Drosophila melanogaster that combines the power to specifically target different neural populations with the label diversity provided by stochastic color choice. This adaptation of vertebrate Brainbow uses recombination to select one of three epitope-tagged proteins detectable by immunofluorescence. Two copies of this construct yield six bright, separable colors. We used Drosophila Brainbow to study the innervation patterns of multiple antennal lobe projection neuron lineages in the same preparation and to observe the relative trajectories of individual aminergic neurons. Nerve bundles, and even individual neurites hundreds of micrometers long, can be followed with definitive color labeling. We traced motor neurons in the subesophageal ganglion and correlated them to neuromuscular junctions to identify their specific proboscis muscle targets. The ability to independently visualize multiple lineage or neuron projections in the same preparation greatly advances the goal of mapping how neurons connect into circuits.",

"EMT is characterized by acquisition of cell motility, modifications of cell morphology, and cell dissociation correlating with the loss of desmosomes from the cellular cortex. A number of growth factors have been shown to be involved in this process. These include fibroblast growth factors (FGFs), TGF-β1, TGF-β2, TNF-α, CCN family, Sonic Hedgehog (SHh), Notch1, GF-β, Wnt, EGF, bFGF, IGF-I and IGF-II."

"Moreover, recent studies have shown that most EMT cases are regulated by soluble growth factors or cytokines. Among these factors, fibroblast growth factors (FGFs) execute diverse functions by binding to and activating members of the FGF receptor (FGFR) family, including FGFR1-4.",
"Fibroblast growth factor receptor 1 is an oncoprotein that is involved in tumorigenesis, and PD173074 is known to be a selective inhibitor of FGFR1.",
"Fibroblast growth factor receptor 1 was also overexpressed in EMT cell lines compared with non-EMT cell lines.",
"Furthermore, treatment of HOC313 cells with PD173074 suppressed cellular proliferation and invasion and reduced ERK1/2 and p38 activation.",
"In addition, the expression levels of certain matrix metalloproteinases (MMPs), whose genes contain activator protein-1 (AP-1) promoter sites, as well as Snail1 and Snail2 were reduced following PD173074 treatment.",
"Taken together, these data suggest that PD173074 inhibits the MAPK pathway, which regulates the activity of AP-1 and induces MET.",
"egulation of Na,K-ATPase β1-subunit in TGF-β2-mediated epithelial-to-mesenchymal transition in human retinal pigmented epithelial cells",
"The EMT process is mediated via exposure to vitreous cytokines and growth factors such as TGF-β2.",
"Previous studies have shown that Na,K-ATPase is required for maintaining a normal polarized epithelial phenotype and that decreased Na,K-ATPase function and subunit levels are associated with TGF-β1-mediated EMT in kidney cells.",
"loss of Na,K-ATPase β1 is a potential contributor to TGF-β2-mediated EMT in RPE cells.",
"MT (epithelial-mesenchymal transition) is crucial for cancer cells to acquire invasive phenotypes. In A549 lung adenocarcinoma cells, TGF-β elicited EMT in Smad-dependent manner and TNF-α accelerated this process, as confirmed by cell morphology, expression of EMT markers, capacity of gelatin lysis and cell invasion.",
"Comprehensive expression analysis unraveled genes differentially regulated by TGF-β and TNF-α, such as cytokines, chemokines, growth factors and ECM (extracellular matrices), suggesting the drastic change in autocrine/paracrine signals as well as cell-to-ECM interactions. ",

"Here we show that CCN1 regulates the Sonic Hedgehog (SHh) signaling pathway, which is associated with the PDAC progression and poor prognosis.",
"SHh regulation by CCN1 in pancreatic cancer cells is mediated through the active Notch-1.",
"These extensive studies propose that targeting CCN1 can provide a new treatment option for patients with pancreatic cancer since blocking CCN1 simultaneously blocks two critical pathways (i.e. SHh and Notch1) associated with the development of the disease as well as drug resistance.",
"GF-β-induced epithelial-mesenchymal transition",
"The cytokine TGF-β, which is expressed by tumor-infiltrating immune cells, stands out as a master regulator of the pro-invasive tumor microenvironment. TGF-β cooperates with stem cell pathways, such as Wnt and Ras signaling, to induce EMT. In addition, TGF-β contributes to an EMT-permissive microenvironment by switching the phenotypes of tumor-infiltrating immune cells, which thereby mount pro-invasive and pro-metastatic immune responses.",

"Upon hypoxia, TGFβ addition or EGFRvIII expression, MCF7, A549 and NMuMG epithelial cells acquired a spindle shape and lost cell-cell contacts. Expression of epithelial markers such as E-cadherin decreased, whereas mesenchymal markers such as vimentin and N-cadherin increased.",
"The EMT process can be regulated by a diverse array of cytokines and growth factors, such as transforming growth factor (TGF)-beta, whose activities are dysregulated during malignant tumor progression.",
"Transforming growth factor-beta-induced tubular cell EMT in C1.1 cells was inhibited by MMP-2/9 inhibitor. Our in vitro study provides evidence that MMPs, specifically MMP-9, secreted by effector macrophages can induce tubular cell EMT and thereby contribute to renal fibrosis.",
"nflammatory cytokines augments TGF-beta1-induced epithelial-mesenchymal transition in A549 cells by up-regulating TbetaR-I",
"In this study, we report that cytomix (a mixture of IL-1beta, TNF-alpha and IFN-gamma) significantly enhances TGF-beta1-induced EMT in A549 cells as evidenced by acquisition of fibroblast-like cell shape, loss of E-cadherin, and reorganization of F-actin.",
"IL-1beta or TNF-alpha alone can also augment TGF-beta1-induced EMT. However, a combination of IL-1beta and TNF-alpha or the cytomix is more potent to induce EMT.",
"These results indicate that inflammatory cytokines together with TGF-beta1 may play an important role in the development of fibrosis and tumor progress via the mechanism of epithelial-mesenchymal transition.",
"TGF-beta stimulated epithelial to mesenchyme transdifferentiation (EMT) in the presence of TGF-alpha, as characterized by increased expression of fibronectin and changes in TGF-beta receptor binding.",
"EMT is typically induced by transforming growth factor-beta1 (TGF-beta1) and inhibited by hepatocyte growth factor (HGF).",
"Exposure of MDCK cells to 10 ng/ml TGF-beta1 for 72 h induced EMT as evidenced by conversion to the spindle-like morphology, loss of E-cadherin, and activation of alpha-smooth muscle actin.",
"In contrast, Akt1 down-regulation in IGF-IR-stimulated cells promoted dramatic neomorphic effects characteristic of an epithelial-mesenchymal transition (EMT) and enhanced cell migration induced by IGF-I or EGF stimulation. The phenotypic effects of Akt1 down-regulation were accompanied by enhanced extracellular signal-related kinase (ERK) activation, which contributed to the induction of migration and EMT.",

"The Aft1 transcription factor regulates the iron regulon in response to iron availability in Saccharomyces cerevisiae. Aft1 activates a battery of genes required for iron uptake under iron-starved conditions, whereas Aft1 function is inactivated under iron-replete conditions. Aft1 interacts with the FOB (ferrioxamine B) transporter Arn3 and may regulate the ubiquitination of Arn3 in the cytosolic compartment. Aft1 has been implicated in numerous cellular processes including cell-cycle progression and chromosome stability. Aft1 has also been shown to affect a diverse range of cellular processes, including the RIM101 pH pathway, cell-wall stability, DNA damage, protein transport, chromosome stability, mitochondrial function, while it was recently shown to interact with the kinetochore protein Iml3 and to promote pericentromeric cohesin."

553e07caf321868558000016 | summary | What is the role of mismatched uracil glycosylase (Mug) in DNA repair? | [
"The mismatch-specific uracil DNA glycosylase (MUG) belongs to a homologous family of DNA glycosylases that initiate base-excision repair of G:U/T mismatches. The crystal structure of the Mug repair complex points to a preference of Mug for G:U over G:T mispairs. Nonetheless, Mug does not repair U:G or T:G mismatches in vivo. Mug possesses xanthine DNA glycosylase (XDG) activity in E.coli. The repair activity of Mug is more robust against xanthine than uracil. Furthermore, Mug excises the alkylated base, 3, N(4)-ethenocytosine (epsilonC) from epsilonC:G mismatches, and may be the only enzyme in E.coli that can remove this mutagenic adduct. Thus, the principal role of Mug may be the repair of DNA damages caused by exogenous chemical agents such as chloroacetaldehyde."

The biogenesis of circular RNA is an integral, conserved, and regulated feature of the gene expression program. Circular RNAs play a crucial role in fine tuning the level of miRNA mediated regulation of gene expression by sequestering the miRNAs. Recent research has revealed that circRNAs can function as microRNA (miRNA) sponges, regulators of splicing and transcription, and modifiers of parental gene expression.",

"No. 2,4-disulfonylphenyl PBN derivative, called NXY-059 in the stroke studies, was shown to be safe in humans and was taken all the way through clinical phase 3 trials and then was deemed to be ineffective."
] | [
"no"
] | [
"Even when the international recommendations for preclinical stroke research, the Stroke Academic Industry Roundtable (STAIR) criteria, were followed, we have still seen limited success in the clinic, examples being NXY-059 and haematopoietic growth factors which fulfilled nearly all the STAIR criteria",
"This occurred during 1993-2006, when the 2,4-disulfonylphenyl PBN derivative, called NXY-059 in the stroke studies, was shown to be safe in humans and was taken all the way through clinical phase 3 trials and then was deemed to be ineffective. ",
"The nitrone-based compound NXY-059, which is the first drug to reach clinical trials for the treatment of acute ischemic stroke, has provided promise for the development of more robust pharmacological agents. ",
"OKN-007 is a proprietary compound that has had extensive commercial development (designated as NXY-059) for another indication, acute ischemic stroke, and after extensive clinical studies was shown to lack efficacy for this indication but was shown to be very safe for human use. ",
"NXY-059, a polar compound with limited transport across the blood-brain barrier, has demonstrated neuroprotection in several animal models of acute ischemic stroke but failed to confirm clinical benefit in the second phase III trial (SAINT-II).",
"NXY-059 is no longer in development following a lack of efficacy found in a Phase III trial in patients with acute ischemic stroke. ",
"We analyzed the quality and adequacy of animal studies supporting the efficacy of NXY-059 and other neuroprotective agents that are currently being investigated in phase II/III trials",
" In the aftermath of the failed stroke clinical trials with the nitrone spin trap/radical scavenger, NXY-059, a number of articles raised the question: are we doing the right thing? ",
" In 2006, the first positive trial of neuroprotection was published: the SAINT I (Stroke-Acute Ischemic NXY Treatment) study. In February 2008, the SAINT II study was published, indicating that NXY-059 was not effective for AIS treatment.",
"CONCLUSIONS: NXY-059 is ineffective for treatment of AIS within 6 hours of symptom onset. ",
"BACKGROUND AND PURPOSE: The SAINT I trial that showed a significant benefit of the neuroprotectant NXY-059 used a novel outcome for acute ischemic stroke trials: a shift toward good functional outcome on the 7-category modified Rankin scale (mRS).",
"BACKGROUND: The free-radical-trapping agent NXY-059 showed promise as a neuroprotectant in the Stroke-Acute Ischemic NXY Treatment I (SAINT I) trial, reducing disability when given to patients who had acute ischemic stroke. ",
"CONCLUSIONS: NXY-059 is ineffective for the treatment of acute ischemic stroke within 6 hours after the onset of symptoms.",
"The continued failure in approving new drugs for treatment of acute stroke has been recently set back by the failure of the NXY-059 (Stroke-Acute Ischemic NXY Treatment (SAINT) II) trial.",
"The SAINT II Trial, a large randomized multicenter clinical trial of the putative neuroprotectant, NXY-059, failed to demonstrate a treatment benefit in acute ischemic stroke. ",
"The positive results from the first Stroke-Acute-Ischaemic-NXY-Treatment (SAINT-I) trial of the free-radical spin-trap drug, NXY-059, which followed many of the STAIR guidelines, reinvigorated enthusiasm in neuroprotection, but the SAINT-II trial did not replicate the positive effect on the same primary prespecified outcome measure. ",
"NXY-059, a free radical spin trap agent, was felt by many to have followed these criteria and it was recently shown to improve outcome in AIS patients in the SAINT I trial. However, the repeat, SAINT II trial was a neutral study, the results of which cast doubt on neuroprotection as a viable strategy for AIS. ",
"NXY-059 is a novel free radical-trapping neuroprotectant that reduces infarct size and preserves brain function in animal models of acute ischemic stroke. It is the first neuroprotectant to demonstrate a reduction in global disability in a phase III clinical trial, as measured by the modified Rankin Scale.",
"BACKGROUND AND PURPOSE: NXY-059 is a free radical-trapping neuroprotectant demonstrated to reduce disability from ischemic stroke.",
"CONCLUSIONS: NXY-059 within 6 hours of acute ischemic stroke significantly reduced disability. ",
"CONCLUSIONS: The administration of NXY-059 within six hours after the onset of acute ischemic stroke significantly improved the primary outcome (reduced disability at 90 days), but it did not significantly improve other outcome measures, including neurologic functioning as measured by the NIHSS score. Additional research is needed to confirm whether NXY-059 is beneficial in ischemic stroke. ",

The exponential growth in the volume of publications in the biomedical domain has made it impossible for an individual to keep pace with the advances. Thus, there is a need for intelligent information retrieval systems that can summarize relevant and reliable textual sources to satisfy a user's query. Question answering is a specialized type of information retrieval with the aim of returning precise short answers to queries posed as natural language questions. This accentuates the need for fast and accurate biomedical question answering systems. In this paper we introduce INDOC -- a biomedical question answering system based on novel ideas of indexing and extracting the answer to the questions posed. Increased access to information allows for more informed and empowered researchers, while information overload becomes an increasingly serious risk. INDOC displays the results in clusters to help the user arrive the most relevant set of documents quickly. Evaluation was done against the standard OHSUMED test collection.

53267871d6d3ac6a3400000a | yesno | Is recommended the use of perioperative treatment with thyroid hormone therapy in patients undergoing coronary artery bypass grafting? | [
"Currently there is no substantial evidence to justify routine use of thyroid hormones in patients undergoing coronary artery bypass grafting."
] | [
"no"
] | [
"Short duration postoperative iv T(3) therapy increases cardiac index and does not alter mortality.",
"We conclude that although widespread interest has been shown on the use of thyroid hormones in the perioperative period, and the effect of cardiopulmonary bypass on thyroid hormone metabolism widely studied, there is no substantial evidence to justify routine use of thyroid hormones in patients undergoing coronary artery bypass grafting.",
"There is no clear evidence at this point to support thyroid hormone replacement in the latter patients, and it may be potentially harmful. Rather, we hold that T3 treatment of various surgical and other patients with nonthyroidal illness should be deferred until proof of its therapeutic efficacy is demonstrated.",
"Perioperative administration of triiodothyronine increased cardiac output slightly and decreased systemic vascular resistance, but it had no effect on operative outcome. Routine use after coronary surgery is thus not recommended.",
"Although mild effects on myocardial performance may exist, we cannot recommend at this time the routine use of intravenous T(3) as an inotropic agent in patients undergoing coronary artery bypass graft surgery.",
"Raising serum triiodothyronine concentrations in patients undergoing coronary-artery bypass surgery increases cardiac output and lowers systemic vascular resistance, but does not change outcome or alter the need for standard postoperative therapy.",
"Thus, there seems to be no sound justification for a routine use of T3 in patients undergoing open-heart procedures."

5159a306d24251bc050000a1 | summary | How does thyroid hormone regulate SR-Ca2+ ATPase (SERCA) protein in the heart? | [
"The thyroid hormone (TH) induced regulation of SERCA is mediated both by non-genomic and genomic actions.\nGenomic actions are mediated by the binding of T(3) receptors (TRs) to the thyroid response elements in the SERCA promotor and result in increased gene expression. \nThyroid hormone increases the transcription of SERCA 2 through three thyroid hormone response elements. \nData show that the regulation of cardiac SERCA by thyroid hormone is made at the pretranslational and possibly transcriptional level \nTRβ1 is shown to be coupled to the expression of SERCA in the heart\nAn increase of TR expression in the hypertrophied heart has been show to result in increased SERCA expression.\nInhibition of TRα1 by dronedarone does not change the expression of SERCA in the heart\nFindings show that SERCA 2 gene expression is regulated by TR isoform-specific interactions with transcription factor (MEF-2) \nHypothyroidism is accompanied by decreased expression of SERCA in the heart. T3 increases expression of the cardiac SERCA\nTH treatment can reverse the reduction in the ratio of SERCA to phospholamban expression which is found in postinfarcted hearts\nTH treatment results in increased expression of SERCA in hearts from banded rats"
] | [] | [
"Furthermore, using specific inhibitors of the TH-activated kinases, we show that the long-term effects of TH on the expression of sarcoplasmic reticulum Ca(2+)-ATPase (SERCA), alpha- and beta-myosin heavy chain (MHC) and cell growth are reverted, implying that what is initiated as a non-genomic action of the hormone interfaces with genomic effects.",
"Hypothyroid neonates showed increased cholesterol levels and decreased expression of D1 in liver and of Serca-2 in heart, which were normalized with T3 treatment.",
"ERCA2 transcript and protein levels were reduced in FOG-2 transgenic hearts, and FOG-2 overexpression impaired T3-mediated SERCA2 expression in cultured cardiomyocytes. FOG-2 physically interacts with thyroid hormone receptor-alpha1 and abrogated even high levels of T3-mediated SERCA2 promoter activity.",
"A marked elevation of the expression of beta-MHC and a reduced ratio of SERCA/Phospholamban were found in viable myocardium of AMI hearts, which was prevented by TH",
"After TH treatment, AMI-THYR hearts expressed 71% alpha-MHC and 29% beta-MHC, P<0.05 versus SHAM and AMI and the ratio of SERCA/PLB was increased by 2.0-fold, P<0.05 versus SHAM and AMI.",
"Because the binding of T(3) occupied receptors to the thyroid response elements in the SERCA promotor can increase gene expression",
"These results demonstrate that increasing TR expression in the hypertrophied heart is associated with an improvement in contractile function and increased SERCA expression.",
"Increased cardiac D2 activity led to elevated cardiac T3 levels and to enhanced myocardial contractility, accompanied by increased Ca(2+) transients and sarcoplasmic reticulum (SR) Ca(2+) uptake. These phenotypic changes were associated with up-regulation of sarco(endo)plasmic reticulum calcium ATPase (SERCA) 2a expression",
"Our results establish that elevated D2 activity in the heart increases T3 levels and enhances cardiac contractile function while preventing deterioration of cardiac function",
"Hypothyroid heart displays a phenotype of cardioprotection against ischemia and this study investigated whether administration of dronedarone, an amiodarone-like compound that has been shown to preferentially antagonize thyroid hormone binding to thyroid hormone receptor alpha1 (TRalpha1), results in a similar effect. Dronedarone was given in Wistar rats (90 mg/kg, once daily (od) for 2 weeks) (DRON), while untreated animals served as controls (CONT). Hypothyroidism (HYPO) was induced by propylthiouracil administration.",
"while beta-myosin heavy chain (beta-MHC) and sarcoplasmic reticulum Ca2+ adenosine triphosphatase (ATPase) expression (SERCA) was similar to CONT. In HYPO, alpha-MHC and SERCA were decreased while beta-MHC was increased.",
"the postnatal switch from beta- to alpha-myosin heavy chain (beta- and alpha-MHC, respectively) gene expression and the increase of SERCA-2a mRNA expression did not occur in the ventricular myocardium of either the transgenic (thyroid destroyed) or nontransgenic (intact thyroid) offspring of hypothyroid mothers",
"In addition, TR cotransfection and treatment with the TRbeta1-selective agonist GC-1 suggested different functional coupling of the TR isoforms, TRbeta1 to transcription of beta-MyHC, SERCA, and TRbeta1,",
"dditionally, in T3-deprived samples alpha-sarcomeric actinin and SERCA-2 protein levels were reduced to 65.6 +/- 3% (P < 0.0001) and 74.1 +/- 4% (P=0.005), respectively, when compared with the T3-supplemented group.",
"even mild chronic myocardial thyrotoxicosis, such as may occur in human hyperthyroidism, can cause tachycardia and associated changes in high energy phosphate compounds independent of an increase in SERCA II and alpha-MHC.",
"Myocytes from banded hearts treated with T4 were hypertrophied but had increased concentrations of alpha-MHC and SERCA proteins",
"Thyroid hormone (T3) increases the transcription of the sarcoplasmic reticulum Ca2+ adenosine triphosphatase (ATPase) gene (SERCA 2) through three thyroid hormone response elements.",
"MEF-2a in combination with either T3R alpha 1 or T3R beta 1 isoforms resulted in a 2.5-fold increase in SERCA 2 transgene expression in the absence of T3. Addition of T3 did not induce any further increase in SERCA 2 expression when T3R alpha 1 and MEF-2a expression vectors were cotransfected. In contrast, in the presence of T3R beta 1 and MEF-2, the addition of T3 increased chlorampenicol acetyltransferase activity by an additional 2.2-fold to a total 5.5-fold increase.",
"Our findings point to T3R isoform-specific interactions with a cell type-specific transcription factor (MEF-2) in the regulation of SERCA 2 gene expression.",
"These data are consistent with pretranslational and possibly transcriptional level effect of thyroid hormone on the cardiac SR Ca2+ pump gene (SERCA 2)",
"These data demonstrate that T3 increases expression of the cardiac SR Ca2+ pump, that the effect can be localized to the cardiomyocyte, and that the effect is dependent on thyroid hormone receptors.",
"Thyroid hormone receptor (TR), a transcriptional activator, affected the regulation of gene expression of MHC and SR Ca(2+)-ATPase.",
"The thyroid hormone responsiveness of SR Ca2(+)-ATPase mRNA has been previously established.",
"The mRNA encoding the sarcoplasmic reticulum (SR) Ca2+ ATPase is highly influenced by thyroid hormone (T3) in the hearts of intact animals.",
"Direct cellular effects of thyroid hormone have been implicated in modulating the expression of the myosin heavy chain (MHC) genes and the slow sarcoplasmic reticulum calcium adenosine triphosphatase (SR Ca(2+)-ATPase) gene."
