What is the function of the Indian hedgehog protein in chondrocytes?
Indian hedgehog is a protein that regulates endochondral differentiation and ossification in both a parathyroid hormone-related protein (PTHrP)-dependent and -independent manner by activating transcriptional mediator Gli2 and is an essential factor for proper skeletal development.

Traditionally, microsporidia were considered as protozoans, but recently they have been reclassified as the earliest-diverging clade of sequenced fungi. Microsporidia are a diverse group of obligate, intracellular, eukaryotic, spore-forming parasites; they are ubiquitous fungi, with genomes that have undergone a strong reduction.

Moreover, looping is dependent upon the general transcription factor TFIIB: the E62K (glutamic acid 62 --> lysine) form of TFIIB adversely affects looping at every gene tested, including BLM10, SAC3, GAL10, SEN1, and HEM3. TFIIB crosslinks to both the promoter and terminator regions of the PMA1 and BLM10 genes, and its association with the terminator, but not the promoter, is adversely affected by E62K and by depletion of the Ssu72 component of the CPF 3' end processing complex, and is independent of TBP.

Can we use prodrug amifostine to protect healthy cell during chemotherapy?
Effective radiotherapy for patients with cancer should include maximal tumor cell killing with minimal injury to normal tissue. However, current radiation doses that can be delivered without causing severe damage to surrounding normal tissues are often insufficient to eradicate a tumor. Recently, a number of agents have been developed to protect normal tissue from the harmful effects of antitumor therapies. The aminothiol amifostine (Ethyol; Alza Pharmaceuticals, Palo Alto, CA/US Bioscience, West Conshohocken, PA) has been the subject of extensive research as a prospective protector. While this drug has been approved for use to reduce toxicities associated with cisplatin, several studies also have demonstrated that amifostine protects normal tissues from both acute and late radiation damage without protecting the tumor. Consequently, higher radiation doses could be used with less than or equal risk to surrounding normal tissues.

What is particular about the mouse Fxy gene's chromosomal position?
We have previously described a gene, Fxy , that spans the pseudoautosomal boundary in mice such that the first three exons of the gene are located on the X chromosome, but the remainder of the gene is located on both X and Y chromosomes. The Fxy gene in mice is also located on the X chromosome but spans the pseudoautosomal boundary in this species.

Are there roles for cohesin mutations in AML?
Yes. Several landmark studies have shown that cohesin mutations perturb the balance between self-renewal and differentiation of hematopoietic stem and progenitor cells (HSPC). Emerging data now begin to uncover the molecular mechanisms that underpin this phenotype. Among these mechanisms is a role for cohesin in the control of inflammatory responses in HSPCs and myeloid cells. Inflammatory signals limit HSPC self-renewal and drive HSPC differentiation. Consistent with this, cohesin mutations promote resistance to inflammatory signals, and may provide a selective advantage for AML progression.

The small molecule SEA0400 is an inhibitor of which ion antiporter/exchanger?
The effects of SEA0400, a selective inhibitor of the Na(+)/Ca(2+) exchanger (NCX), on Na(+)-dependent Ca(2+) uptake and catecholamine (CA) release were examined in bovine adrenal chromaffin cells that were loaded with Na(+) by treatment with ouabain and veratridine. SEA0400 inhibited Na(+)-dependent (45)Ca(2+) uptake and CA release, with the IC(50) values of 40 and 100 nM, respectively.

Describe CapSim
CapSim is a software package for simulation of targeted capture sequencing. Given a genome sequence and a set of probes, CapSim simulates the fragmentation, the dynamics of probe hybridization and the sequencing of the captured fragments on Illumina and PacBio sequencing platforms. The simulated data can be used for evaluating the performance of the analysis pipeline, as well as the efficiency of the probe design. Parameters of the various stages in the sequencing process can also be evaluated in order to optimize the experiments.Availability and implementation: CapSim is publicly available under BSD license at https://github.com/Devika1/capsim.

Does replication timing affect the rate of somatic mutations?
Mutation rate, as reflected in recent evolutionary divergence and human nucleotide diversity, is markedly increased in later-replicating regions of the human genome. All classes of substitutions are affected, suggesting a generalized mechanism involving replication time-dependent DNA damage. DNA repair systems, in general, are less efficient in late replicating heterochromatic regions compared to early replicating euchromatic regions of the genome. In yeast the mutation rate increases with the replication timing by more than 30% between the earliest and the latest replicating regions. Limited evidence from one chromosome arm in Drosophila melanogaster suggests the opposite pattern, with regions overlapping early-firing origins showing increased levels of diversity and divergence. In humans DNA replication patterns help shape the mutational landscapes of normal and cancer genomes.

Are genomic regulatory blocks (GRBs) any different than TADs?
No, clusters of CNEs (GRBs) strongly coincide with topological organisation, predicting the boundaries of hundreds of topologically associating domains (TADs) in human and Drosophila. The set of TADs that are associated with high levels of noncoding conservation exhibit distinct properties compared to TADs devoid of extreme noncoding conservation. The close correspondence between extreme noncoding conservation and TADs suggests that these TADs are ancient, revealing a regulatory architecture conserved over hundreds of millions of years.

what is the role of TGFbeta in cardiac regeneration after myocardial injury?
TGFβ is activated in the myocardium in response to injury and plays a crucial role in cardiac repair by suppressing inflammation while promoting myofibroblast phenotypic modulation and extracellular matrix deposition. In fact, upregulation of TGF-beta signaling promotes the formation of a myofibroblast-like phenotype. TGF-beta interacts with bone morphogenic protein and Wnt pathways to form a complex signaling network that is critical in regulating the fate choices of both stromal and tissue-specific resident stem cells, determining whether functional regeneration or the formation of scar tissue follows an injury. In addition, TGF-beta enhances the formation of cardiospheres and could potentially enhance the regenerative potential of adult cardiac progenitor cells.
