![]() These results reveal a vulnerability of hypertranscribing stem cells to endogenous DNA breaks, with important implications for developmental and cancer biology. Genes prone to DNA breaks in Chd1-null ES cells tend to be longer genes with GC-rich promoters, a more labile nucleosomal structure and roles in chromatin organization, transcription and signaling. Loss of Chd1 leads to an extensive accumulation of DSBs at Chd1 target Pol II genes and rDNA. We show that wild-type ES cells display high levels of phosphorylated H2AX and Kap1 at chromatin, notably at rDNA in the nucleolus, in a Chd1-dependent manner. NVivo - NVivo replaced HyperRESEARCH and HyperTRANSCRIBE PDF Creator. An unbiased proteomics approach revealed that Chd1 interacts with several DNA repair factors including ATM, Parp1, Kap1 and Topoisomerase 2. Autodesk Design Review - CAD viewer software BlueGriffon - A WYSIWYG web site. Here we report a novel role for Chd1 in the repair of promoter-proximal endogenous double-stranded DNA breaks (DSBs) in ES cells. Biochemically, Chd1 has been shown to facilitate transcription at least in part by removing nucleosomal barriers to elongation, but its mechanism of action in stem cells remains poorly understood.

The chromatin remodeler Chd1 binds to RNA Pol I and II genes and is required for hypertranscription in embryonic stem (ES) cells in vitro and the early post-implantation epiblast in vivo. HyperTRANSCRIBE version 1.0 (HyperTRANSCRIBE.exe). ![]() Summary: Hypertranscription supports biosynthetically demanding cellular. It can export your text to RTF or plain text for use in any other program, such as Microsoft Word or ResearchWare’s HyperRESEARCH software after transcribing. and provides access to high quality, open access, peer-reviewed journals. ![]() Stem and progenitor cells undergo a global elevation of nascent transcription, or hypertranscription, during key developmental transitions involving rapid cell proliferation.
