516e5f41298dcd4e5100007f | factoid | What is the genetic basis of Rubinstein-Taybi syndrome? | [
"Rubinstein-Taybi syndrome (RTS) is a rare autosomal dominant disorder (prevalence 1:125,000) characterised by broad thumbs and halluces, facial dysmorphism, psychomotor development delay, skeletal defects, abnormalities in the posterior fossa and short stature. The known genetic causes are a microdeletion at 16p13.3 or mutations or deletions of the cAMP-response element binding protein-BP (CREBBP) (50-60% of the cases) and of the homologous gene E1A-binding protein (EP300) at 22q13 (5%). Direct sequencing of CREBBP performed in 13 RSTS patients identified the three zinc fingers (CH1, CH2, CH3) and HAT domain as mutational hotspots. Thus about 55% of patients have cytogenetic or molecular abnormalities in the Crebbp or E1A binding protein p300 (Ep300) gene, leaving the diagnosis in 45% of patients to rest on clinical features only."

] | [
"The Rubinstein-Taybi syndrome (RTS) is a well-defined syndrome with facial abnormalities, broad thumbs, broad big toes and mental retardation as the main clinical features",
"Many patients with RTS have been shown to have breakpoints in, and microdeletions of, chromosome 16p13.3",
"these breakpoints are restricted to a region that contains the gene for the human CREB binding protein (CBP), a nuclear protein participating as a co-activator in cyclic-AMP-regulated gene expression",
"RTS was shown to be associated with disruption of the CREB-binding protein gene CBP (CREBBP), either by gross chromosomal rearrangements or by point mutations",
"Genetic heterogeneity in Rubinstein-Taybi syndrome: mutations in both the CBP and EP300 genes cause disease",
"A certain level of CREB-binding protein is essential for normal development, since inactivation of one allele causes Rubinstein-Taybi syndrome (RSTS)",
"In 92 patients, we were able to identify a total of 36 mutations in CBP",
"We extended the search for mutations to the EP300 gene and showed that mutations in EP300 also cause this disorder.",
"Mutations in the CREBBP (CREB-binding protein gene) cause Rubinstein-Taybi syndrome (RSTS).",
"Heterozygous CREBBP mutations were identified in 12 of the 21 patients: five frameshift mutations, three nonsense mutations, two splice-site mutations, and two missense mutations.",
"It could be possible that genetic heterogeneity is related with novel mutations in other genes.",
"identified a novel CREBBP missense mutation, c.2728A > G (predicting p.Thr910Ala)",
"The p.Thr910Ala variant is outside the crucial histone acetyltransferase domain, and this may explain the mild and variable phenotype",
"Rubinstein-Taybi syndrome (RSTS), a developmental disorder comprising abnormalities that include mental retardation, an unusual facial appearance, broad thumbs and big toes is frequently associated with molecular lesions in the CREB-binding protein gene, CREBBP",
"Direct sequencing of CREBBP performed in 13 RSTS patients identified the three zinc fingers (CH1, CH2, CH3) and HAT domain as mutational hotspots in which ten novel pathogenic mutations were localized"

"KP4 is a virally encoded and highly specific toxin that kills fungi closely related to the fungus Ustilago maydis.",
"The P4 strain of the corn smut fungus, Ustilago maydis, secretes a fungal toxin, KP4, encoded by a fungal virus (UMV4) that persistently infects its cells.",
"These results led to experiments demonstrating that the toxin specifically inhibits voltage-gated Ca2+ channels in mammalian cells.",
"Ustilago maydis killer toxins are small polypeptides (7-14 kDa) which kill susceptible cells of closely related fungal species. The KP4 toxin is a single polypeptide subunit with a molecular weight of 11.1 kDa"

56ed27012ac5ed145900000b | factoid | What is the function of the AIRE gene at the embryonic stage? | [
"Aire regulates the expression of differentiation-associated genes and self-renewal of embryonic stem cells. Aire and Deaf1 help regulate the ectopic expression of diverse tissue-specific antigens to establish self-immune tolerance. Knockdown of Aire in mouse ESCs resulted in significantly decreased clone-forming efficiency as well as attenuated cell cycle, suggesting Aire plays a role in ESC self-renewal. Aire promotes the expression of the pluripotent factor Lin28 and the self-renewal of ES cells.",
"Autoimmune regulator (Aire) is one of the most well-characterized molecules in autoimmunity, but its function outside the immune system is largely unknown. The recent discovery of Aire expression in stem cells and early embryonic cells and its function in the self-renewal of embryonic stem (ES) cells highlight the importance of Aire in these cells.",
"The recent discovery of Aire expression in stem cells and early embryonic cells and its function in the self-renewal of embryonic stem (ES) cells highlight the importance of Aire in these cells. The correlation between Aire and Lin28 expression in germ cells and early embryos indicated an in vivo function for Aire in toti- and pluripotent stem cells. Moreover, it presents the first evidence that microRNAs contribute to the regulatory function of Aire and highlights a novel function of Aire in stem cell biology and reproduction. Monitoring Aire expression in MSCs may thus be a critical parameter for clinical use."

"These functional assessments (1-minute walk, LSU, and 10-meter walk tests) are simple to administer, quick, low cost, and user-friendly. Although these assessments are not a substitute for the criterion standard (GMFM-88), they may be used for a quick assessment in adolescents with cerebral palsy (levels I-III) either at school or during rehabilitation, especially when time is limited",

"Neurofibromatosis type 1 and Noonan syndrome are both common genetic disorders with autosomal dominant inheritance.",
"Molecular analysis showed a missense mutation in exon 25 of the NF1 gene (4288A>G, p.N1430D)",
"Identification of forty-five novel and twenty-three known NF1 mutations in Chinese patients with neurofibromatosis type 1",
"Neurofibromatosis type 1 (NF1), characterized by skin neurofibromas and an excess of café-au-lait spots, is due to mutations in the neurofibromin (NF1) gene. Identifying the genetic defect in individuals with the disease represents a significant challenge because the gene is extremely large with a high incidence of sporadic mutations across the entire gene ranging from single nucleotide substitutes to large deletions.",
"Fifty-eight were initially identified using heteroduplex analytical techniques and confirmed by sequence analysis. A further five were identified by direct sequence analysis alone. The reminders were shown to carry large deletions in the NF1 gene by demonstrating loss of heterozygosity that was confirmed by gene dosage measurements using quantitative-PCR techniques. Mis-sense, non-sense, frame-shift or splice-site mutations were identified across the entire gene of which the majority (45/68) were novel in nature.",
"Neurofibromatosis type 1 (NF1) is a common tumor predisposition syndrome affecting approximately 1 in 4,000 persons. It is an autosomal-dominant disorder with half of the cases resulting from spontaneous mutations.",
"Characterization of the somatic mutational spectrum of the neurofibromatosis type 1 (NF1) gene in neurofibromatosis patients with benign and malignant tumors",
"Ninety-one tumors from 31 NF1 patients were screened for gross changes in the NF1 gene using microsatellite/restriction fragment length polymorphism (RFLP) markers; loss of heterozygosity (LOH) was found in 17 out of 91 (19%) tumors (including two out of seven MPNSTs). Denaturing high performance liquid chromatography (DHPLC) was then used to screen 43 LOH-negative and 10 LOH-positive tumors for NF1 microlesions at both RNA and DNA levels. Thirteen germline and 12 somatic mutations were identified, of which three germline (IVS7-2A>G, 3731delT, 6117delG) and eight somatic (1888delG, 4374-4375delCC, R2129S, 2088delG, 2341del18, IVS27b-5C>T, 4083insT, Q519P) were novel. A mosaic mutation (R2429X) was also identified in a neurofibroma by DHPLC analysis and cloning/sequencing.",
"The region of DNA located between two translocation breakpoints has been cloned and a DNA sequence encoding a 11-13 kb mRNA identified. That this sequence shows deletions and point mutations in NF1 affected individuals and not in normal controls provides strong evidence that it is indeed the NF1 gene."

"Thus, TGFβ signaling orchestrates the beneficial interplay between scar-based repair and cardiomyocyte-based regeneration to achieve complete heart regeneration.",
"As expected, transforming growth factor (TGF)-beta, a profibrotic cytokine, was dramatically upregulated in MI hearts, but its phosphorylated comediator (pSmad) was significantly downregulated in the nuclei of Cx43-deficient hearts post-MI, suggesting that downstream signaling of TGF-beta is diminished substantially in Cx43-deficient hearts. This diminution in profibrotic TGF-beta signaling resulted in the attenuation of adverse structural remodeling as assessed by echocardiography.",

"TGF-beta conducted the myogenic differentiation of CD117+ stem cells by upregulating GATA-4 and NKx-2.5 expression. Therefore, the intramyocardial implantation of TGF-beta-preprogrammed CD117+ cells effectively assisted the myocardial regeneration and induced therapeutic angiogenesis, contributing to functional cardiac regeneration.",

"Amantadine, a dopaminergic agent, has been shown to be effective for induction of recovery from disorders of consciousness. Amantadine is a commonly prescribed medication for patients with prolonged disorders of consciousness after traumatic brain injury. Amantadine accelerates the pace of functional recovery during active treatment in patients with post-traumatic disorders of consciousness. Higher dosing of amantadine may be considered in the setting of brain injury."

] | [
"We here provide a systematic overview of the therapeutic effects of amantadine, apomorphine and zolpidem in patients recovering from coma. Evidence from clinical trials using these commonly prescribed pharmacological agents suggests positive changes in the neurological status in patients, leading sometimes to dramatic improvements.",
"Pharmaceuticals that act in the oxygen based amino acid systems of the brain include the GABAergic medications zolpidem and baclofen, while those that act in the monoamine axes include the dopaminergic medications L Dopa, amantadine, bromocriptine, apomorphine and methylphenidate, and the noradrenergic and serotonergic medications desipramine, amitriptyline, protriptyline and fluoxetine. ",
"Sporadic cases of recovery from a DOC have been reported after the administration of various pharmacological agents (baclofen, zolpidem, amantadine etc.).",
"Amantadine hydrochloride is one of the most commonly prescribed medications for patients with prolonged disorders of consciousness after traumatic brain injury. Preliminary studies have suggested that amantadine may promote functional recovery.",
" During the 4-week treatment period, recovery was significantly faster in the amantadine group than in the placebo group, as measured by the DRS score (difference in slope, 0.24 points per week; P=0.007), indicating a benefit with respect to the primary outcome measure. ",
"Amantadine accelerated the pace of functional recovery during active treatment in patients with post-traumatic disorders of consciousness.",
"Sporadic cases of dramatic recovery from DOC after the administration of various pharmacological agents, such as baclofen, zolpidem and amantadine, have been recently supported by intriguing scientific observations. ",
"According to the 16 eligible studies, medical management by dopaminergic agents (levodopa, amantadine), zolpidem and median nerve stimulation, or surgical management by deep brain stimulation, extradural cortical stimulation, spinal cord stimulation and intrathecal baclofen have shown to improve the level of consciousness in certain cases. ",
"Higher exposure of amantadine (average concentration of amantadine during 6 mg/kg/day > 1.5 mg/L) may be associated with better recovery of consciousness. ",
"Based on the preliminary data, higher dosing may be considered in the setting of brain injury.",
"Patients treated with PK-Merz exhibited the more significant restoration of consciousness and better dynamics (regress) of neurological deficit with the most intensive restoration of neurological deficit in the first day that allows to recommend the use of amantadine sulfate in the first hours of ischemic stroke and for the prevention of reperfusion damage in recanalisation therapy of ischemic stroke.",
"There was no significant difference in the slopes of recovery during either arm for the Coma/Near-Coma Scale (P = 0.24) or the Coma Recovery Scale-Revised (P = 0.28), although improvements in consciousness were noted by the physician during weeks when amantadine was given (P = 0.02). ",
"This study suggests that amantadine facilitates recovery of consciousness in pediatric acquired brain injury and provides important information necessary to design future more definitive studies.",
"The study has shown a positive effect of this drug at coma emergence, which manifested itself as clinical improvement and a better outcome of the disease.",
"This article will review the evidence for the use of psychostimulants (methylphenidate), antidepressants (amitriptyline, selective serotonin reuptake inhibitors, and buproprion), Parkinson's medications (amantadine, bromocriptine, carbidopa/levodopa), anticonvulsants (valproic acid), modafinil (Provigil), lactate, hyperbaric oxygen chamber, electroconvulsive therapy, and transmagnetic stimulation, in patients following a head injury.",
"Of the psychoactive medications, amantadine hydrochloride was associated with greater recovery and dantrolene sodium was associated with less recovery, in terms of the DRS score at 16 weeks but not the time until commands were followed."

In the fruit fly, simple feeding with spermidine inhibited loss of climbing activity and early organismal death upon heterologous expression of human α-synuclein, which is thought to be the principal toxic trigger of Parkinson's Disease (PD). In this line, administration of spermidine rescued α-synuclein-induced loss of dopaminergic neurons, a hallmark of PD, in nematodes. Alleviation of PD-related neurodegeneration by spermidine was accompanied by induction of autophagy, suggesting that this cytoprotective process may be responsible for the beneficial effects of spermidine administration."

"Mass spectrometric analysis revealed serine-42, a conserved amino acid in the chromodomain, as a phosphorylation site of Cbx2. Phosphorylation of the chromodomain of Cbx2 on this residue in vitro resulted in a reduced level of binding to an H3 peptide containing trimethylated lysine-9 as well as an increase in the extent of binding to an H3 peptide containing trimethylated lysine-27, suggesting that such phosphorylation changes the binding specificity of Cbx2 for modified histone H3. Phosphorylation of the chromodomain of Cbx2 may therefore serve as a molecular switch that affects the reading of the histone modification code and thereby controls epigenetic cellular memory.",

"MRG15 is a novel chromodomain protein that is a member of a family of genes related to MORF4. MORF4 (mortality factor on chromosome 4) induces senescence in a subset of human tumor cell lines.",
"Analysis of deletion mutants of MRG15 indicated that the leucine zipper at the C-terminal region of MRG15 was important for the protein associations in MAF1 and that the N-terminal chromodomain was required for the assembly of the MAF2 protein complex. Consistent with these data was the fact that a histone acetyltransferase activity associated with MRG15 was lost when the chromodomain was deleted and that both mutant MRG15 proteins failed to activate the B-myb promoter.

56b3efc38525abca1e000006 | summary | What is Genomicus? | [
"Genomicus had been developed as a database and a browser to study gene synteny in modern and ancestral genomes. It allows easy comparative genomic visualization in >150 eukaryote genomes and in four different phyla (Vertebrate, Fungi, Metazoan and Plants). It provides a way to explore spatial information related to gene organization within and between genomes and temporal relationships related to gene and genome evolution. For the specific vertebrate phylum, it also provides access to ancestral gene order reconstructions and conserved non-coding elements information. The graphical modules of Genomicus show how it is capable of revealing differential gene loss and gain, segmental or genome duplications and facilitate the study of the evolution of a locus through homology relationships. The Genomicus server provides access to ancestral gene orders, as well as computationally predicted regulatory interactions, thanks to the representation of conserved non-coding elements with their putative gene targets."

For the specific vertebrate phylum, it also provides access to ancestral gene order reconstructions and conserved non-coding elements information. We extended the Genomicus database originally dedicated to vertebrate to four new clades, including plants, non-vertebrate metazoa, protists and fungi.

"The Genomicus web server (http://www.genomicus.biologie.ens.fr/genomicus) is a visualization tool allowing comparative genomics in four different phyla (Vertebrate, Fungi, Metazoan and Plants). It provides access to genomic information from extant species, as well as ancestral gene content and gene order for vertebrates and flowering plants. Here we present the new features available for vertebrate genome with a focus on new graphical tools. The interface to enter the database has been improved, two pairwise genome comparison tools are now available (KaryoView and MatrixView) and the multiple genome comparison tools (PhyloView and AlignView) propose three new kinds of representation and a more intuitive menu. These new developments have been implemented for Genomicus portal dedicated to vertebrates. This allows the analysis of 68 extant animal genomes, as well as 58 ancestral reconstructed genomes.

"Although considered to be a class III anti-arrhythmic, amiodarone also has class I, II and IV actions, which gives it a unique pharmacological and anti-arrhythmic profile",
"Amiodarone has been used as an anti-arrhythmic drug since the 1970s and has an established role in the treatment of ventricular tachyarrhythmias.

" tick-borne encephalitis (TBE) have been detected in Bulgaria. Considering the remarkable increase in TBE morbidity in Europe over the past two decades, we conducted a study of TBE among patients with acute viral meningitis who were hospitalised in Bulgaria during 2009 to 2012. ",
"Viruses belonging to the Flaviviridae family primarily spread through arthropod vectors, and are the major causes of illness and death around the globe. The Flaviviridae family consists of 3 genera which include the Flavivirus genus (type species, yellow fever virus) as the largest genus, the Hepacivirus (type species, hepatitis C virus) and the Pestivirus (type species, bovine virus diarrhea). The flaviviruses (Flavivirus genus) are small RNA viruses transmitted by mosquitoes and ticks that take over host cell machinery in order to propagate. However, hepaciviruses and pestiviruses are not antropod-borne. Despite the extensive research and public health concern associated with flavivirus diseases, to date, there is no specific treatment available for any flavivirus infections, though commercially available vaccines for yellow fever, Japanese encephalitis and tick-born encephalitis exist."

"There have been a few case reports to suggest that ceftriaxone can be effective for treatment of amyotrophic lateral sclerosis. However, other case reports did not report clinical benefit of ceftriaxone therapy for ALS. Ceftriaxone has been reported to reduce neuronal damage in amyotrophic lateral sclerosis a through increased expression and activity of the glutamate transporter, GLT1. Clinical trials investigating potential clinical benefits of ceftriaxone in ALS are ongoing."

"OBJECTIVES: Ceftriaxone increases expression of the astrocytic glutamate transporter, EAAT2, which might protect from glutamate-mediated excitotoxicity. ",
"Thirty-four compounds (including riluzole, ceftriaxone, minocyclin, PBA, lithium, acetylcysteine) in human and mouse ALS trials and an additional set of 1040 FDA-approved compounds also showed no effect on SOD1 promoter activity. ",
"Two of these patients received ceftriaxone for 1 month without clinical improvement.",
"In amyotrophic lateral sclerosis, down-regulation of the astrocyte-specific glutamate excitatory amino acid transporter 2 is hypothesized to increase extracellular glutamate, thereby leading to excitotoxic motor neuron death. The antibiotic ceftriaxone was recently reported to induce excitatory amino acid transporter 2 and to prolong the survival of mutant superoxide dismutase 1 transgenic mice.",
"OBJECTIVE: Ceftriaxone has been reported to reduce neuronal damage in amyotrophic lateral sclerosis and in an in-vitro model of neuronal ischaemia through increased expression and activity of the glutamate transporter, GLT1. ",
"Dysfunction of EAAT2 is implicated in acute and chronic neurological disorders, including stroke/ischemia, temporal lobe epilepsy, amyotrophic lateral sclerosis, Alzheimer disease, human immunodeficiency virus 1-associated dementia, and growth of malignant gliomas. Ceftriaxone, one of the beta-lactam antibiotics, is a stimulator of EAAT2 expression with neuroprotective effects in both in vitro and in vivo models based in part on its ability to inhibit neuronal cell death by glutamate excitotoxicity.

"Other agents (ceftriaxone, minocycline, ONO-2506, and IGF-1 polypeptide) are already in phase III trials involving large numbers of patients with ALS.",
"Ongoing trials are exploring the value of antiglutamatergic agents, including the cephalosporin antibiotic ceftriaxone, as well as antioxidants, mitochondrial enhancers and anti-apoptotic drugs. ",
"Recently, Rothstein et al. reported that beta-lactam antibiotics, including penicillin and ceftriaxone, are potential therapeutic drugs to treat some neurological disorders, e.g., amyotrophic lateral sclerosis (ALS), by modulating the expression of glutamate transporter GLT1 via gene activation.

"We describe two patients with lateral amyotrophic sclerosis who, after informed consent, received empirical treatment with intravenous cephtriaxone at a dose of 2 g/24 hours for three weeks, with no positive results.",
"Despite promising stage 2 data, stage 3 of this trial of ceftriaxone in amyotrophic lateral sclerosis did not show clinical efficacy.",
" Importantly, ceftriaxone is currently in clinical trials for the treatment of amyotrophic lateral sclerosis.",
"The cephalosporin antibiotic ceftriaxone was evaluated as a potential therapeutic agent for the treatment of amyotrophic lateral sclerosis (ALS)."

"One of these tests, Oncotype DXtrade mark, is a diagnostic test comprised of a 21-gene assay applied to paraffin-embedded breast cancer tissue, which allows physicians to predict subgroups of hormone-receptor-positive, node-negative patients who may benefit from hormonal therapy alone or require adjuvant chemotherapy to attain the best survival outcome.",
"We tested if Oncotype DX and TAILORx risk categories could be predicted by standard pathological features and protein markers corresponding to 10 genes in the assay (ER, PR, Ki67, HER2, BCL2, CD68, Aurora A kinase, survivin, cyclin B1 and BAG1) on 52 patients who enrolled on TAILORx",

"479 consecutive patients were included in the study, of whom 241 (50%) underwent Oncotype DX testing, 97 as part of the TAILORx clinical trial. Oncotype DX testing began on a trial basis in 2007 and until October 2011, only patients enrolled on TAILORx availed of genomic profiling.",

"Mean levels of fasting plasma estradiol, luteinizing hormone, follicle-stimulating hormone, free thyroxine and triiodothyronine were significantly lower in AR compared to ER and SE.",
"Reductions in plasma T4, T3 and T3/T4 ratio are probably due to inhibition of T4 secretion and 5'-monodeiodination with possible conversion of T4 to reverse T3 (rT3). These processes may represent a mechanism for regulation of thyroid hormone metabolism during strenuous and extended flight.",
"Strenuous endurance training seems to have minor changes on the function of the thyroid gland. Depressed T4 levels in runners may rather be due to lowered TBG levels than due to direct effect of training.",

" In 19 of 142 patients (13%), the PLN founder mutation c.40_42delAGA (p.Arg14del) was identified. PLN mutation carriers more often had low-voltage electrocardiograms (p = 0.004), inverted T waves in leads V4 to V6 (p <0.001), and additional structural (p = 0.007) or functional (p = 0.017) left ventricular impairment, whereas desmosomal mutation carriers had more solitary right ventricular abnormalities.",
"Recently, we showed that the c.40_42delAGA (p.Arg14del) mutation in the phospholamban (PLN) gene can be identified in 10-15 % of Dutch patients with dilated cardiomyopathy or arrhythmogenic cardiomyopathy.",
"PLN mutation R14del was identified in 12 (12 %) ARVC patients and in 39 (15 %) DCM patients. ",
"The PLN R14del founder mutation is present in a substantial number of patients clinically diagnosed with DCM or ARVC. R14del+ patients diagnosed with DCM showed an arrhythmogenic phenotype, and SCD at young age can be the presenting symptom. These findings support the concept of 'arrhythmogenic cardiomyopathy'.",
"Herein we reveal mechanistic insight into how four hereditary mutants of phospholamban, Arg(9) to Cys, Arg(9) to Leu, Arg(9) to His, and Arg(14) deletion, alter regulation of SERCA. Deletion of Arg(14) disrupts the protein kinase A recognition motif, which abrogates phospholamban phosphorylation and results in constitutive SERCA inhibition. Mutation of Arg(9) causes more complex changes in function, where hydrophobic substitutions such as cysteine and leucine eliminate both SERCA inhibition and phospholamban phosphorylation, whereas an aromatic substitution such as histidine selectively disrupts phosphorylation. We demonstrate that the role of Arg(9) in phospholamban function is multifaceted: it is important for inhibition of SERCA, it increases the efficiency of phosphorylation, and it is critical for protein kinase A recognition in the context of the phospholamban pentamer. Given the synergistic consequences on contractility, it is not surprising that the mutants cause lethal, hereditary dilated cardiomyopathy.",
"Phospholamban (PLN) is a key regulator of SR and cardiac function, and PLN mutations in humans have been associated with dilated cardiomyopathy (DCM). We previously reported the deletion of the highly conserved amino acid residue arginine 14 (nucleic acids 39, 40 and 41) in DCM patients.",
"To assess the function of this mutant PLN, we introduced the PLN-R14Del in cardiac myocytes of the PLN null mouse.",
"Thus, human PLN-R14Del is misrouted to the sarcolemma, in the absence of endogenous PLN, and alters NKA activity, leading to cardiac remodeling.",
"Mutations in the gene encoding PLN have been associated with idiopathic dilated cardiomyopathy; however, no systematic search for PLN mutations in heart failure has been conducted.",
"Two patients presented a G-T missense mutation at the G26 nucleotide, which encodes an Arg-Leu substitution at codon 9 (R9L).",
"One patient presented a G-A missense mutation at the same nucleotide, which encodes an Arg-His substitution at codon 9 (R9H). The fourth affected patient presented a T-G nonsense mutation at the nucleotide 116, substituting a termination codon for Leu-39 (L39stop).",
"The genetic analysis was focused on R9C mutation with the ability to block PLN phosphorylation leading to chronic inhibition of SERCA2a activity. Another analysed mutation causing the alteration of PLN level in cells was related to the substitution of a leucine residue at position 39 with a premature stop codon (L39X). ",
"A missense mutation in PLN cytoplasmic domain (R9C) triggers dilated cardiomyopathy in humans, leading to premature death. ",
"These effects are enhanced under oxidizing conditions, suggesting that oxidative stress may exacerbate the cardiotoxic effects of the PLN(R9C) mutant. ",
"We identified 1 family with a deletion of arginine 14 in the PLN. Interestingly, unlike other individuals reported with the identical PLN mutation, these individuals were not diagnosed with dilated cardiomyopathy until their seventh decade when they were only mildly symptomatic with congestive heart failure. ",
"Phospholamban R14 deletion results in late-onset, mild, hereditary dilated cardiomyopathy.",
"Through genetic screening of dilated cardiomyopathy patients, we identified a previously uncharacterized deletion of arginine 14 (PLN-R14Del) in the coding region of the phospholamban (PLN) gene in a large family with hereditary heart failure. No homozygous individuals were identified. By middle age, heterozygous individuals developed left ventricular dilation, contractile dysfunction, and episodic ventricular arrhythmias, with overt heart failure in some cases.",
"Transgenic mice overexpressing the mutant PLN-R14Del recapitulated human cardiomyopathy exhibiting similar histopathologic abnormalities and premature death.",
"A mutation in the human phospholamban gene, deleting arginine 14, results in lethal, hereditary cardiomyopathy.",
"Here, a T116G point mutation, substituting a termination codon for Leu-39 (L39stop), was identified in two families with hereditary heart failure. The heterozygous individuals exhibited hypertrophy without diminished contractile performance. Strikingly, both individuals homozygous for L39stop developed dilated cardiomyopathy and heart failure, requiring cardiac transplantation at ages 16 and 27. ",
"Here we report that an inherited human dilated cardiomyopathy with refractory congestive heart failure is caused by a dominant Arg --> Cys missense mutation at residue 9 (R9C) in phospholamban (PLN), a transmembrane phosphoprotein that inhibits the cardiac sarcoplasmic reticular Ca2+-adenosine triphosphatase (SERCA2a) pump. Transgenic PLN(R9C) mice recapitulated human heart failure with premature death. Cellular and biochemical studies revealed that, unlike wild-type PLN, PLN(R9C) did not directly inhibit SERCA2a. Rather, PLN(R9C) trapped protein kinase A (PKA), which blocked PKA-mediated phosphorylation of wild-type PLN and in turn delayed decay of calcium transients in myocytes. ",

5311cdcce3eabad021000007 | yesno | Is there any software for automated analysis of FISH images? | [
"FISH is a popular molecular cytogenetic method. The output of a single FISH analysis is a set of several tens or hundreds microscopic images — a single evaluated sample is of roughly 20mm diameter. The goal of an automated evaluation is to replace the subjective evaluation of images by the laboratory technician to achieve higher uniformity of results. Following explanation of the principle of the method and the typical contents of images, the processing flow of image segmentation is outlined and the results are presented on several example images. Based on results there are software for automated analysis of FISH images."

"he study demonstrated the feasibility of automated FISH signal analysis that applying a CAD scheme to the automated generated 2-D projection images.",
"A color imaging technique, multiplex fluorescent in situ hybridization (M-FISH), has been developed to ease the analysis of the process. Using an M-FISH technique each chromosome class (1,2, …,22,X,Y) is stained with a unique color. However, significant variations between images are observed due to a number of factors such as uneven hybridization and spectral overlap among channels. These types of variations influence the pixel classification accuracy of image classification methods which are supervised and require a set of annotated images for training. In this paper, we present a fully unsupervised M-FISH chromosome image classification methodology. Our main contributions are 1) the assumption that the intensity of a chromosome pixel is sampled from multiple Gaussian components [Gaussian mixture model (GMM)] such that each component corresponds to one chromosome class, and 2) the initialization of the GMM model using the emission information of each chromosome class. This is feasible since prior to the M-FISH image acquirement, we already know which chromosome class is emitting to each of the five M-FISH image channels. The method has been tested on a large number of M-FISH images and an overall accuracy of 89.85% is reported. Our method is unsupervised and presents higher classification accuracy even when it is compared with common supervised based methods.",
"hybridization (FISH) tests provide promising molecular imaging biomarkers to more accurately and reliably detect and diagnose cancers and genetic disorders. Since current manual FISH signal analysis is low-efficient and inconsistent, which limits its clinical utility, developing automated FISH image scanning systems and computer-aided detection (CAD) schemes has been attracting research interests. To acquire high-resolution FISH images in a multi-spectral scanning mode, a huge amount of image data with the stack of the multiple three-dimensional (3-D) image slices is generated from a single specimen. Automated preprocessing these scanned images to eliminate the non-useful and redundant data is important to make the automated FISH tests acceptable in clinical applications. In this study, a dual-detector fluorescence image scanning system was applied to scan four specimen slides with FISH-probed chromosome X. A CAD scheme was developed to detect analyzable interphase cells and map the multiple imaging slices recorded FISH-probed signals into the 2-D projection images. CAD scheme was then applied to each projection image to detect analyzable interphase cells using an adaptive multiple-threshold algorithm, identify FISH-probed signals using a top-hat transform, and compute the ratios between the normal and abnormal cells. To assess CAD performance, the FISH-probed signals were also independently visually detected by an observer. The Kappa coefficients for agreement between CAD and observer ranged from 0.69 to 1.0 in detecting/counting FISH signal spots in four testing samples.",
" In this paper we developed a sparse representation-based classification (SRC) algorithm based on L1-norm minimization for classifying chromosomes from multicolor fluorescence in situ hybridization (M-FISH) images. The algorithm has been tested on a comprehensive M-FISH database that we established, demonstrating improved performance in classification. When compared with other pixel-wise M-FISH image classifiers such as fuzzy c-means (FCM) clustering algorithms and adaptive fuzzy c-means (AFCM) clustering algorithms that we proposed earlier the current method gave the lowest classification error. In order to evaluate the performance of different SRC for M-FISH imaging analysis, three different sparse representation methods, namely, Homotopy method, Orthogonal Matching Pursuit (OMP), and Least Angle Regression (LARS), were tested and compared. Results from our statistical analysis have shown that Homotopy based method is significantly better than the other two methods. ",
"Fluorescence in situ hybridization (FISH) is used to study the organization and the positioning of specific DNA sequences within the cell nucleus. Analyzing the data from FISH images is a tedious process that invokes an element of subjectivity. Automated FISH image analysis offers savings in time as well as gaining the benefit of objective data analysis. While several FISH image analysis software tools have been developed, they often use a threshold-based segmentation algorithm for nucleus segmentation. As fluorescence signal intensities can vary significantly from experiment to experiment, from cell to cell, and within a cell, threshold-based segmentation is inflexible and often insufficient for automatic image analysis, leading to additional manual segmentation and potential subjective bias. To overcome these problems, we developed a graphical software tool called FISH Finder to automatically analyze FISH images that vary significantly. By posing the nucleus segmentation as a classification problem, compound Bayesian classifier is employed so that contextual information is utilized, resulting in reliable classification and boundary extraction. This makes it possible to analyze FISH images efficiently and objectively without adjustment of input parameters. Additionally, FISH Finder was designed to analyze the distances between differentially stained FISH probes.",
"The simultaneous detection of protein expression and gene copy number changes in patient samples, like paraffin-embedded tissue sections, is challenging since the procedures of immunohistochemistry (IHC) and Fluorescence in situ Hybridization (FISH) negatively influence each other which often results in suboptimal staining. Therefore, we developed a novel automated algorithm based on relocation which allows subsequent detection of protein content and gene copy number changes within the same cell. METHODS: Paraffin-embedded tissue sections of colorectal cancers were stained for CD133 expression. IHC images were acquired and image coordinates recorded. Slides were subsequently hybridized with fluorescently labeled DNA probes. FISH images were taken at the previously recorded positions allowing for direct comparison of protein expression and gene copy number signals within the same cells/tissue areas. Relocation, acquisition of the IHC and FISH images, and enumeration of FISH signals in the immunophenotyped tumour areas were done in an automated fashion. RESULTS: Automated FISH analysis was performed on 13 different colon cancer samples that had been stained for CD133; each sample was scored for MYC, ZNF217 and Chromosome 6 in CD133 positive and negative glands. From the 13 cases four (31%) showed amplification for the MYC oncogene and seven of 13 (54%) cases were amplified for ZNF217.",

51659356298dcd4e5100005a | summary | How do histone methyltransferases cause histone modification? | [
"Histone methyltransferases (HMTs) are responsible for the site-specific addition of covalent modifications on the histone tails, which serve as markers for the recruitment of chromatin organization complexes. There are two major types of HMTs: histone-lysine N-Methyltransferases and histone-arginine N-methyltransferases. The former methylate specific lysine (K) residues such as 4, 9, 27, 36, and 79 on histone H3 and residue 20 on histone H4. The latter methylate arginine (R) residues such as 2, 8, 17, and 26 on histone H3 and residue 3 on histone H4. Depending on what residue is modified and the degree of methylation (mono-, di- and tri-methylation), lysine methylation of histones is linked to either transcriptionally active or silent chromatin."
] | [] | [
"Lysine methylation of histones is associated with both transcriptionally active chromatin and with silent chromatin, depending on what residue is modified. Histone methyltransferases and demethylases ensure that histone methylations are dynamic and can vary depending on cell cycle- or developmental stage.",
"This approach identified Txr1p as a histone methyltransferase in Tetrahymena thermophila and characterized the relationships of the Txr1p and Ezl2p methyltransferases to histone H3 modification.",
"Histone methyltransferases catalyze site-specific deposition of methyl groups, enabling recruitment of transcriptional regulators. In mammals, trimethylation of lysine 4 in histone H3, a modification localized at the transcription start sites of active genes, is catalyzed by six enzymes (SET1a and SET1b, MLL1-MLL4) whose specific functions are largely unknown. ",
"Epigenetic regulation of gene expression by covalent modification of histones is important for germ line cell development. In mammals, histone H3 lysine 9 (H3K9)-specific histone methyltransferases (HMTases), such as G9a, SETDB1, and SUV39H, play critical roles, but the contribution of H3K9-specific HMTases in Drosophila remains to be clarified, especially in male sperm.",
"By analyzing the distribution of histone modifications in nuclei using quantitative fluorescence microscopy, we found that H4K16 acetylation (H4K16ac) is underrepresented and H4K20 monomethylation (H4K20me1) is enriched on hermaphrodite X chromosomes in a DCC-dependent manner. ",
" Here, we found the epigenetic modification of the BZLF1 promoter in latent Raji cells by histone H3 lysine 27 trimethylation (H3K27me3), H3K9me2/me3, and H4K20me3. ",
"Although DNA methyltransferases have been shown to interact with histone methyltransferases such as EZH2 (which methylates histone H3 on lysine 27) and G9a (which methylates histone H3 on lysine 9), the relationship between DNA methylation and repressive histone marks has not been fully studied. ",
"Methylation of histone H4 lysine 20 (H4K20me) plays critical roles in diverse cellular processes such as gene expression, cell cycle progression and DNA damage repair, with each of the three degrees of methylation (mono-, di- and tri-methylation) making a unique contribution. ",
"Histone H3-lysine (K) 4, H3-K9 and H3-K27 modifications in all these four genes were examined by chromatin immunoprecipitation (ChIP) assay in HCC cell lines. ",
"The histone H4 N-terminal tail has long been regarded as a major regulator in chromatin structure and function.",
"Gene transcription is critically influenced by chromatin structure and the modification status of histone tails. Methylation of lysine residues in histone tails is dynamically regulated by the opposing activities of histone methyltransferases and histone demethylases.",
"The SAS3-dependent NuA3 histone acetyltransferase complex was originally identified on the basis of its ability to acetylate histone H3 in vitro.",
"SU(VAR)3-9 like histone methyltransferases control heterochromatic domains in eukaryotes.",
"Methylation of position-specific lysine residues in histone N termini is a central modification for regulating epigenetic transitions in chromatin. Each methylatable lysine residue can exist in a mono-, di-, or trimethylated state, thereby extending the indexing potential of this particular modification. ",
"One of these modifications, histone lysine methylation, has been shown to be highly stable and to represent an epigenetic alteration.",
"Primarily because of the recent discovery of the SET domain-depending H3-specific histone methyltransferases SUV39H1 and Suv39h1, which selectively methylate lysine 9 of the H3 N terminus, this posttranslational modification has regained scientific interest.",
"Set9, a novel histone H3 methyltransferase that facilitates transcription by precluding histone tail modifications required for heterochromatin formation.",
"Our results suggest that the methylation of histone tails can have distinct effects on transcription, depending on its chromosomal location, the combination of posttranslational modifications, and the enzyme (or protein complex) involved in the particular modification.",
"Among the different groups of enzymes known to catalyze the covalent modification, the most recent additions are the histone methyltransferases (HMTases), whose functions are now being characterized."

Accordingly, miR-21 is proven to be involved in the pathogenesis of the above-mentioned cardiovascular diseases as demonstrated by both loss-of-function and gain-of-function approaches"
] | [

"The synergistic effect of miR-21 and miR-1 were functionally validated for their significant influences on myocardial apoptosis, cardiac hypertrophy and fibrosis.",
"Taken together, we found a novel reciprocal loop between miR-21 and TGFβRIII in cardiac fibrosis caused by myocardial infarction in mice, and targeting this pathway could be a new strategy for the prevention and treatment of myocardial remodeling.",
"It is still controversial whether microRNA-21 (miR-21) participates in the process of cardiac fibrosis.",
"In mice, myocardial miR-21 overexpression is related to cardiac fibrosis elicited by pressure overload. ",
"The myocardial and plasma levels of miR-21 were significantly higher in the AS patients compared with the controls and correlated directly with the echocardiographic mean transvalvular gradients.",
"Our results support the role of miR-21 as a regulator of the fibrotic process that occurs in response to pressure overload in AS patients and underscore the value of circulating miR-21 as a biomarker for myocardial fibrosis.",
"Ad-miR-21 improves LV remodeling and decreases the apoptosis of myocardial cells, suggesting the possible mechanism by which Ad-miR-21 functions in protecting against I/R injury.",
"In the Ad-miR-21 group, LV dimensions, myocardial infarct size, LV/BW, collagen type Ⅰ, type Ⅲ and PCNA positive cells all significantly decreased compared with the Ad-GFP group.",
"While miR-21, -133, -150, -195, and -214 regulate cardiomyocyte hypertrophy, miR-1/-133 and miR-208 have been elucidated to influence myocardial contractile function. In addition, miR-21, -24, -133, -210, -494, and -499 appear to protect myocytes against I/R-induced apoptosis, whereas miR-1, -29, -199a, and -320 promote apoptosis. Myocardial fibrosis can be regulated by the miR-29 family and miR-21.",

"Remarkably, miR-21 was one of most upregulated miRNAs in hearts after IP. In vivo, IP-mediated cardiac protection against ischaemia/reperfusion injury was inhibited by knockdown of cardiac miR-21. In cultured cardiac myocytes, we identified that miR-21 also had a protective effect on hypoxia/reoxygenation-induced cell apoptosis that was associated with its target gene, programmed cell death 4. The protective effect of miR-21 on cardiac cell apoptosis was further confirmed in rat hearts after ischaemia/reperfusion injury in vivo.",
"Lately, some highlight articles revealed that the altered expression of miRNAs such as miR-1, miR-133, miR-21, miR-208 etc in hearts also contributed to cardiovascular diseases, such as heart ischemia, cardiac hypertrophy, and arrhythmias.",
"Remarkably, miR-21 expression was significantly down-regulated in infarcted areas, but was up-regulated in border areas. The down-regulation of miR-21 in the infarcted areas was inhibited by ischemic preconditioning, a known cardiac protective method. Overexpression of miR-21 via adenovirus expressing miR-21 (Ad-miR-21) decreased myocardial infarct size by 29% at 24 h and decreased the dimension of left ventricles at 2 weeks after AMI. Using both gain-of-function and loss-of-function approaches in cultured cardiac myocytes, we identified that miR-21 had a protective effect on ischemia-induced cell apoptosis that was associated with its target gene programmed cell death 4 and activator protein 1 pathway. The protective effect of miR-21 against ischemia-induced cardiac myocyte damage was further confirmed in vivo by decreased cell apoptosis in the border and infarcted areas of the infarcted rat hearts after treatment with Ad-miR-21. The results suggest that miRNAs such as miR-21 may play critical roles in the early phase of AMI.",
"The results suggest that miR-21 is sensitive to H(2)O(2) stimulation. miR-21 participates in H(2)O(2)-mediated gene regulation and functional modulation in cardiac myocytes. miR-21 might play an essential role in heart diseases related to ROS such as cardiac hypertrophy, heart failure, myocardial infarction, and myocardial ischemia/reperfusion injury.",

"E3 ligase activity of BRCA1 is not essential for mammalian cell viability or homology-directed repair of double-strand DNA breaks.",
"The protein encoded by BRCA1 interacts in vivo with the related BARD1 protein to form a heterodimeric complex that acts as a ubiquitin E3 ligase. Because the enzymatic activity of the BRCA1/BARD1 heterodimer is conserved over a broad phylogenetic range, it is thought to be critical for the central functions of BRCA1.",
"A mechanism for transcriptional repression dependent on the BRCA1 E3 ubiquitin ligase.",
"In this study, we identified an ubiquitin-dependent mechanism by which BRCA1 inhibits transcription. BRCA1 ubiquitinates the transcriptional preinitiation complex, preventing stable association of TFIIE and TFIIH, and thus blocks the initiation of mRNA synthesis. ",
"In the structure the arrangement of the Ring-domains is similar to another H2A E3 ligase, the BRCA1/BARD1 complex, but complex formation depends on an N-terminal arm of Ring1b that embraces the Bmi1 Ring-domain.",
"Discovering the precise function of the breast and ovarian specific tumor suppressor, BRCA1, has proven to be quite complicated. It has been determined that BRCA1, together with BARD1, comprise an E3 ubiquitin ligase. Since it is now known that BRCA1 is an enzyme, the challenge for BRCA1 research is to learn how this enzymatic activity functions in normal breast and ovarian cells in order to suppress cancerous transformation.",
"The BRCA1 tumor suppressor gene is expressed in all mammalian cells. Within these cells, the BRCA1 protein product interacts with several seemingly distinct nuclear complexes. Proteins within these complexes are potential targets for the E3-ubiquitin ligase activity associated with BRCA1:BARD1 complexes. ",
"During both DNA replication and DNA repair, BRCA1 appears to serve both adaptor and enzymatic functions. Roles include transient physical recruitment of NBS1, gammaH2AX, FANCD2 and other proteins in specific repair associated complexes, and enzymatic activity as an E3-ubiquitin ligase against a subset of these proteins. ",
"The BRCA1 protein displays E3 ubiquitin ligase activity, and this enzymatic function is thought to be required for tumor suppression."

"N-glycolylneuraminic acid (Neu5Gc) is an immunogenic sugar of dietary origin that metabolically incorporates into diverse native glycoconjugates in humans. Humans lack a functional cytidine monophosphate-N-acetylneuraminic acid hydroxylase (CMAH) protein and cannot synthesize the sugar Neu5Gc, an innate mammalian signal of self. N-Glycolylneuraminic acid (Neu5Gc) can be incorporated in human cells and can trigger immune response, a response that is diverse and polyclonal.

"Novel oral anticoagulants (NOACs)--apixaban, dabigatran, and rivaroxaban--have a significantly smaller risk of intracerebral hemorrhage (ICH). However, two facts make this situation complicated: First, the risk of hematoma expansion is unknown for NOACs. Second, there is no specific antidote for neither of the NOACs.",
"he new oral anticoagulants dabigatran etexilate (Pradaxa), rivaroxaban (Xarelto), and apixaban (Eliquis) have predictable pharmacokinetic and pharmacodynamic profiles and are alternatives to warfarin. However, many physicians are wary of these drugs, since there is limited evidence on how to manage bleeding in patients taking them, and since no specific antidote is known to reverse their anticoagulant effect. ",
"Given the absence of a specific antidote, the action to be taken in these situations must be defined. ",
"The fact that there is no specific antidote to reverse the anticoagulant action of the new anticoagulants can impair management of hemorrhagic complications; ",
"Like any new therapy, the potential benefits must be weighed against the potential challenges and one of the most concerning aspects of the new target-specific oral anticoagulants is the lack of a proven method to reverse their effect. Unlike the vitamin K antagonist, i.e. warfarin, there is no specific antidote for these medications. ",
"Two major drawbacks are on the one hand the risk of drug accumulation in kidney and/or liver disease and, on the other hand, the lack of specific antidotes.",
"NOA also have other unresolved problems: drug interactions are still possible, specific coagulation test to assess them must be developed, and no specific antidote is currently available in case of hemorrhagic complication.",
"But they have disadvantages also, they depend on renal clearance, they can interact with other medicaments and they lack a specific antidote. ",
"While these trial data are extremely encouraging, several practical issues (e.g., lack of specific antidote, safety of long-term treatment or cost-effectiveness in \"real-life\" clinical practice) still need to be elucidated.",
"In case of massive bleeding, management is unclear and none of these newer agents has a specific antidote that completely reverses its anticoagulant effect.",
"The short half-life of these new agents compensates for the lack of any specific antidote in many instances. ",
"Currently, none of these new agents has a specific antidote, and little advise can be given on how to manage a major bleeding event.",
"Rivaroxaban, which inhibits activated factor X (Xa), is currently in clinical trials and is the most advanced factor Xa inhibitor. The drug offers once-daily oral dosing, with no need for injections, dose titration, or frequent blood tests to monitor the international normalised ratio. It has a rapid onset of action and, although there is no specific antidote, it has a short plasma elimination half-life (about 5-9 hours). ",
"Increased use of dabigatran, rivaroxaban, and apixaban as oral anticoagulants for the treatment of atrial fibrillation and acute deep venous thrombosis has increased despite the lack of known antidotes to these medications.",
"There is no antidote for reversal and no reliable laboratory monitoring of the anticoagulant effect for emergency situations. ",
"Further concerns about the use of NOAC in the elderly are the high prevalence of renal insufficiency in AF patients >75 years of age, the largely unknown risk of drug-drug and drug-food interactions, the lack of easily available laboratory monitoring tests of anticoagulant activity and the lack of an antidote.",
"Specific antidotes for the reversal of the anticoagulant effect of these drugs, such as monoclonal antibodies against the direct thrombin inhibitor dabigatran or recombinant Xa-analog in the case of factor Xa inhibitors, are still being investigated in early clinical trials.",
"In early 2013 there is no antidote for dabigatran, rivaroxaban or apixaban, nor any specific treatment with proven efficacy for severe bleeding linked to these drugs. "

Cultures grown with elevated CO(2) /bicarbonate exhibited increased AtxA dimer/monomer ratios and increased AtxA activity, relative to cultures grown without added CO(2) /bicarbonate, suggesting that this host-associated signal enhances AtxA function by shifting the dimer/monomer equilibrium towards the dimeric state. CO2-enhanced toxin gene transcription is not observed in atx4-null mutants. Overall data indicate a clear association of atxA with CO2-enhanced gene expression in B. anthracis and provide evidence that atxA regulates genes other than the structural genes for the anthrax toxin proteins.",
"Comparison of the resulting protein patterns indicated that synthesis of non-toxin proteins is influenced by growth in elevated CO2 and the toxin gene regulator, atxA.

"EZH2 mutations that cause Weaver syndrome are primarily missense variants and the rare truncating mutations reported to date are in the last exon, suggesting that simple haploinsufficiency is unlikely to be generating the overgrowth phenotype although the exact mechanism has not yet been determined. Recent studies have shown that EZH2 mutations are often associated with RUNX1 mutations in MDS patients, although its pathological function remains to be addressed. These data show that mutations in EZH2 cause Weaver syndrome. The EZH2 gene is a homolog of the Drosophila Polycomb group (PcG) gene enhancer of zest, a crucial regulator of homeotic gene expression.",
"Loss-of-function mutations of EZH2, a catalytic component of polycomb repressive complex 2 (PRC2), are observed in ~\\n10% of patients with myelodysplastic syndrome (MDS), but are rare in acute myeloid leukaemia (AML). Constitutional NSD1 and EZH2 mutations cause Sotos and Weaver syndromes respectively, overgrowth syndromes with considerable phenotypic overlap. Mutations at tyrosine 641 (Y641F, Y641N, Y641S and Y641H) in the SET domain of EZH2 have been identified in patients with certain subtypes of non-Hodgkin lymphoma (NHL).

"The complexity in composition and function of the eukaryotic nucleus is achieved through its organization in specialized nuclear compartments. Chromosome conformation capture approaches have shown that interphase chromatin is partitioned into spatially segregated Mb-sized compartments and sub-Mb-sized topological domains. This compartmentalization is thought to facilitate the matching of genes and regulatory elements.

"We begin by showing that depletion for UCEs characterizes the most recent large-scale human CNV datasets and then find that even newly formed de novo CNVs, which have passed through meiosis at most once, are significantly depleted for UCEs. In striking contrast, CNVs arising specifically in cancer cells are, as a rule, not depleted for UCEs and can even become significantly enriched. This observation raises the possibility that CNVs that arise somatically and are relatively newly formed are less likely to have established a CNV profile that is depleted for UCEs. Alternatively, lack of depletion for UCEs from cancer CNVs may reflect the diseased state. In support of this latter explanation, somatic CNVs that are not associated with disease are depleted for UCEs. Finally, we show that it is possible to observe the CNVs of induced pluripotent stem (iPS) cells become depleted of UCEs over time, suggesting that depletion may be established through selection against UCE-disrupting CNVs without the requirement for meiotic divisions.",

511979b04eab811676000003 | summary | How could we infer functional associations from gene fusion events? | [
"The detection of gene fusion events across genomes can be used for the prediction of functional associations of proteins, based on the observation that related proteins in one organism (including physically interacting proteins/members of complexes, proteins involved in the same pathway) tend to be found in other species as a fused composite gene encoding a single multifunctional protein. For this purpose, gene fusion events may be used as the sole evidence or as independent information combined with other 'genome-aware' or similarity-based methods, and functional association may be predicted at different levels. An advantage of this approach is that it is not necessary to know the function of the composite/components to infer association."
] | [] | [
"Gene fusion is an important evolutionary process. It can yield valuable information to infer the interactions and functions of proteins.",
"We have developed a Bayesian framework to infer phosphorylation networks from time series measurements of phosphosite concentrations upon ligand stimulation. To increase the prediction accuracy we integrated different types of data, e.g., amino acid sequence data, genomic context data (gene fusion, gene neighborhood, and phylogentic profiles)",
"It is assumed that two proteins, which are found to be transcribed by a single transcript in one (or several) genomes are likely to be functionally linked, for example by acting in a same metabolic pathway or by forming a multiprotein complex. This method is of particular interest for studying genes that exhibit no, or only remote, homologies with already well-characterized proteins.",
"PLEX search results are accompanied by quantitative estimates of linkage confidence, enabling users to take advantage of coinheritance, operon and gene fusion-based methods for inferring gene function and reconstructing cellular systems and pathways.",
"While phylogenomic profiles remain the central focus of Phydbac2, it now integrates chromosomal proximity and gene fusion analyses as two additional non-similarity-based indicators for inferring pairwise gene functional relationships.",
"detection of gene fusion events can contribute towards the elucidation of functional associations of proteins within entire genomes",
"Inference of gene function based on gene fusion events: the rosetta-stone method.",
"protein domain fusions in human protein interaction networks prediction",
"Some proteins, involved in a common biological process and encoded by separate genes in one organism, can be found fused within a single protein chain in other organisms. By detecting these triplets, a functional relationship can be established between the unfused proteins.",
"These results suggest that domain fusion is an appropriate method for predicting protein complexes.",
"The detection of gene fusion events across genomes can be used for the prediction of functional associations of proteins, including physical interactions or complex formation.",
"These genomic constraints form the basis for a variety of techniques that employ systematic genome comparisons to predict functional associations among genes. The most powerful techniques to date are based on conserved gene neighborhood, gene fusion events, and common phylogenetic distributions of gene families",
"Functional links between proteins can often be inferred from genomic associations between the genes that encode them: groups of genes that are required for the same function tend to show similar species coverage, are often located in close proximity on the genome (in prokaryotes), and tend to be involved in gene-fusion events.",
"Genes linked by fusion events are generally of the same functional category",
"a functional association between two genes can be derived from the existence of a fusion of the two as one continuous sequence in another genome",
"Protein interaction maps for complete genomes based on gene fusion events",
"Because there must be selective pressure for certain genes to be fused over the course of evolution, we are able to predict functional associations of proteins.",
"We observed that gene fusion events are more related to physical interaction between proteins than to other weaker functional relationships such as participation in a common biological pathway.",
"FusionDB provides a characterization of a large number of gene fusion events at hand of multiple sequence alignments.",
"Domain fusion analysis has been proposed recently to infer the functional association of the component proteins.",
"Here we present a method that identifies gene-fusion events in complete genomes, solely based on sequence comparison."

"Yes, several compounds that inhibit different members of the proteasome pathway (for example Bortezomib) are on trial for treatment of leukemia and solid tumors. It seems that a combination with other drugs may be a useful therapy for solid tumors."
] | [
"yes"
] | [
"We show that treatment with b-AP15 inhibited tumor progression in four different in vivo solid tumor models and inhibited organ infiltration in an acute myeloid leukemia model. Our results show that the deubiquitinating activity of the 19S regulatory particle is a new anticancer drug target",
"We further found that ATO targets AME via both myelodysplastic syndrome 1 (MDS1) and EVI1 moieties and degrades EVI1 via the ubiquitin-proteasome pathway and MDS1 in a proteasome-independent manner. Our results suggest that ATO could be used as a part of targeted therapy for AME-, AML1/MDS1-, MDS1/EVI1-, and EVI1-positive human cancers.",
"Previously we had shown the synergic effect of bortezomib and thiostrepton in breast cancer cells in vitro, where sub-apoptotic concentrations of both proteasome inhibitors resulted in synergic increase in cell death when combined as a treatment. Here, we administered such a combination to MDA-MB-231 xenograft tumors in vivo, and found that the effect of complementary proteasome inhibitors reduced tumor growth rates more efficiently than compared with when administered alone.",
"Addition of a proteasome inhibitor to anti-hormonal therapy resulted in a clinical benefit rate of 22% in a limited number of patients with endocrine resistant and progressive metastatic breast cancer.",
"Taken together, these data support the clinical development of MLN9708 for both hematologic and solid tumor indications.",
"Bortezomib has minimal activity as a single-agent in the treatment of recurrent platinum-sensitive EOC/PPC",
"Our study indicates a molecular mechanism by which the sensitivity of thyroid cancer cells is regulated by the level of GRP78 as well as preferential induction of GRP78 or CHOP upon treatment with proteasome inhibitors. Our experiments therefore suggest a novel approach toward sensitization of thyroid cancer cells to proteasome inhibitors.",
"Bortezomib (PS-341) is a novel antineoplastic agent that is well tolerated at doses not exceeding 3.0 mg (equivalent to 1.75 mg/m2), repeated on D1 and D4 every other week. This dose correlates with 70% inhibition of 20S proteasome activity.",
"The maximum-tolerated dose and recommended phase II dose of bortezomib in this schedule is 1.6 mg/m(2). Biologic activity (inhibition of nuclear factor-kappa B-related markers) and antitumor activity is seen in AIPCa at tolerated doses of bortezomib.",
"Given the results of this trial, it is safe and reasonable to recommend treatment with PS341 on the schedule used in this trial at 1.56 mg/m2/dose in Phase II trials. Particular care should be taken with patients with preexisting neuropathy",
"The successes of proteasome inhibitors in MM are now being translated to other hematologic malignancies, including acute leukemia",
"Such efforts have led to bortezomib, the first FDA approved proteasome inhibitor now used as a frontline treatment for newly diagnosed multiple myeloma (MM), relapsed/refractory MM and mantle cell lymphoma",
"We recently reported the impact and mechanisms of carfilzomib and oprozomib, second-in-class proteasome inhibitors with higher specificities and reduced toxicities, against head and neck squamous cell carcinoma (HNSCC). Carfilzomib and oprozomib potently inhibit HNSCC cell survival and the growth of HNSCC tumors"

"Yes. CTF4 and CTF18 are required for high-fidelity chromosome segregation. Both exhibit genetic and physical ties to replication fork constituents. Absence of either CTF4 or CTF18 causes sister chromatid cohesion failure and leads to a preanaphase accumulation of cells that depends on the spindle assembly checkpoint. The physical and genetic interactions between CTF4, CTF18, and core components of replication fork complexes suggest that both gene products act in association with the replication fork to facilitate sister chromatid cohesion."
] | [
"yes"

"Our results suggest that Elg1, Ctf4, and Ctf18 may coordinate the relative movement of the replication fork with respect to the cohesin ring",
"These data defined two cohesion pathways, one containing CSM3, TOF1, CTF4, and CHL1, and the second containing MRC1, CTF18, CTF8, and DCC1",
"Here we show that three proteins required for sister chromatid cohesion, Eco1, Ctf4, and Ctf18, are found at, and Ctf4 travels along chromosomes with, replication forks. The ring-shaped cohesin complex is loaded onto chromosomes before S phase in an ATP hydrolysis-dependent reaction. Cohesion establishment during DNA replication follows without further cohesin recruitment and without need for cohesin to re-engage an ATP hydrolysis motif that is critical for its initial DNA binding. This provides evidence for cohesion establishment in the context of replication forks and imposes constraints on the mechanism involved",
"Sister-chromatid cohesion mediated by the alternative RF-CCtf18/Dcc1/Ctf8, the helicase Chl1 and the polymerase-alpha-associated protein Ctf4 is essential for chromatid disjunction during meiosis II",
"In budding yeast, a specialized replication factor C called RF-C(Ctf18/Dcc1/Ctf8) and the DNA-polymerase-alpha-associated protein Ctf4 are required to maintain sister-chromatid cohesion in cells arrested for long periods in mitosis",
"We also show that, in contrast to mitosis, RF-C(Ctf18/Dcc1/Cft8), Ctf4 and Chl1 are essential for chromosome segregation during meiosis and for the viability of meiotic products.",
"Ctf8p is a component of Ctf18-RFC, an alternative replication factor C-like complex required for efficient sister chromatid cohesion in Saccharomyces cerevisiae. We performed synthetic genetic array (SGA) analysis with a ctf8 deletion strain as a primary screen to identify other nonessential genes required for efficient sister chromatid cohesion. We then assessed proficiency of cohesion at three chromosomal loci in strains containing deletions of the genes identified in the ctf8 SGA screen. Deletion of seven genes (CHL1, CSM3, BIM1, KAR3, TOF1, CTF4, and VIK1) resulted in defective sister chromatid cohesion",

"Genomic Regions Enrichment of Annotations Tool (GREAT) is a tool to analyse the functional significance of cis-regulatory regions identified by localised measurements of DNA binding events across an entire genome. Whereas previous methods took into account only binding proximal to genes, GREAT is able to properly incorporate distal binding sites and control for false positives using a binomial test over the input genomic regions. GREAT incorporates annotations from 20 ontologies and is available as a web application. Applying GREAT to data sets from chromatin immunoprecipitation coupled with massively parallel sequencing (ChIP-seq) of multiple transcription-associated factors, including SRF, NRSF, GABP, Stat3 and p300 in different developmental contexts, many functions of these factors are recovered that are missed by existing gene-based tools, and testable hypotheses are generated. The utility of GREAT is not limited to ChIP-seq, as it could also be applied to open chromatin, localized epigenomic markers and similar functional data sets, as well as comparative genomics sets."

"When TFs are bound to active regulatory regions, they displace canonical nucleosomes, making these regions biochemically detectable as nucleosome-depleted regions or accessible/open chromatin. Here we ask whether open chromatin profiling can be used to identify the entire repertoire of active promoters and enhancers underlying tissue-specific gene expression during normal development and oncogenesis in vivo. To this end, we first compare two different approaches to detect open chromatin in vivo using the Drosophila eye primordium as a model system: FAIRE-seq, based on physical separation of open versus closed chromatin; and ATAC-seq, based on preferential integration of a transposon into open chromatin.

" Cumulative survival was significantly lower among patients with free triiodothyronine < 2.12 pg/mL and among patients with brain natriuretic peptide > 686 pg/mL. In multivariate analysis, the significant independent predictors of major cardiac events were age, free triiodothyronine, and brain natriuretic peptide",
"The T3 was more meaningful than the BNP in the prognosis of CHF. The BNP and T3 combination detection was more valuable in determining the severity of CHF and prognosis.",
"fT3 and BNP hold an independent and additive prognostic value in HF.",
"Univariate regression analysis showed that TSH (p<0.0001), fT3 (p<0.0001), fT4 (p=0.016) and fT3/fT4 (p<0.0001) were associated with heart failure progression but multivariate analysis showed that only TSH considered as a continuous variable (p = 0.001) as well as subclinical hypothyroidism (TSH > 5.5 mUI/l; p=0.014) remained significantly associated with the events.",
"Low T(3) levels are an independent predictor of mortality in patients with chronic heart failure, adding prognostic information to conventional clinical and functional cardiac parameters.",
"Sixteen patients (14%) died during the follow-up period; their fT3/fT4 ratio was significantly lower than the patients who survived (1.31+/-0.37 vs. 2.01+/-0.72, p<0.001).",
"The authors conclude that among elderly patients with heart failure, lower triiodothyronine concentrations are more prevalent and are associated with a worse prognosis.",
"A low free T3 index/reverse T3 ratio is associated with poor ventricular function and nutritional status and is the strongest predictor yet identified for short-term outcome in patients with advanced heart failure."
