WebJan 7, 2014 · Deciphering the molecular basis of pluripotency is fundamental to our understanding of development and embryonic stem cell function. ... CTCF directly recruits TAF3 to promoter distal sites and ... Web1 day ago · Having identified a reduction in fragile nucleosome occupancy upon Smarca4 depletion at established (promoter, CTCF-bound) and novel (gene-distal DHS) fragile nucleosome-bound genomic locations, we next examined whether this change occurs over other genomic locations, including nucleosome remodeling factor and pluripotency …
WebJun 27, 2016 · Abstract. The CCCTC-binding factor (CTCF) is an architectural protein that governs chromatin organization and gene expression in somatic cells. Here, we show … WebMar 22, 2024 · CTCF is a highly conserved zinc-finger DNA-binding protein that mediates interactions between distant sequences in the genome. As a consequence, CTCF regulates enhancer-promoter interactions and contributes to the three-dimensional organization of the genome. ... In mESCs and hESCs, pluripotency genes such as Oct4 and Nanog, as …
WebJun 19, 2011 · Here we applied chromatin interaction analysis by paired-end tag (ChIA-PET) sequencing to elucidate the CTCF-chromatin interactome in pluripotent cells. From this … WebSep 25, 2012 · CTCF is involved in the regulation of both miR-125b1 and miR-375, indicating that there are various patterns of CTCF-associated epigenetic regulation of miRNAs. CTCF may also play a key role in the pluripotency of cells through the regulation of miR-290 cluster. These observations suggest that CTCF-mediated regulation of …
WebApr 1, 2024 · Here, we show that Ctcf expression is progressively increased during induced pluripotency. In this process, CTCF first functions as a chromatin insulator responsible …
WebThe X chromosome that now contains the pluripotency factors and CTCF proteins will continue to express the Tsix RNA and will remain active. The other X chromosome (without the pluripotency factors and CTCF proteins) turns off Tsix expression and begins to express the Xist RNA. As a result, the X chromosome that expresses Xist will be … how to reset lg fridgeWebMar 1, 2024 · CTCF is an upstream regulator of the pluripotency factor Oct4. CTCF interacts with Oct4, and they share a substantial number of target genes. CTCF and Oct4 co-occupy the promoters of linc1253 and linc1356 genes, and … north cemetery wayland maWebMay 16, 2024 · In addition to rich maps of chromatin protein occupancy from 50 cells, we were able to map the genome-wide binding sites of CTCF and two pluripotency TFs, SOX2 and NANOG, in single cells. Because each individual TF binding site is present in only 2–4 copies per diploid cell, single-cell TF profiling is a considerable technical challenge. northcenterWebSep 20, 2024 · We also performed ChIP-seq with antibodies to CTCF, RAD21, and ZNF143, which co-localizes extensively with CTCF and cohesin (Bailey et al., 2015), AP-1, the pluripotency factors NANOG, OCT4, and KLF4, and the … how to reset lenovo t490sWebApr 10, 2024 · Although the importance of genome organization for transcriptional regulation of cell-fate decisions and function is clear, the changes in chromatin architecture and how these impact effector and memory CD8 + T cell differentiation remain unknown. Using Hi-C, we studied how genome configuration is integrated with CD8 + T cell differentiation … north center apartmentsWebThe double homeobox (Dux) gene, encoding a double homeobox transcription factor, is one of the key drivers of totipotency in mice. Recent studies showed Dux was temporally expressed at the 2-cell stage and acted as a transcriptional activator during zygotic genome activation (ZGA) in embryos. A similar activation occurs in mouse embryonic stem cells, … how to reset lg refrigerator temperatureWebWe found that loss of pluripotency is accompanied by widespread gain of structural loops. This general architectural change correlates with enhanced binding of CTCF and cohesins and more pronounced insulation of contacts across chromatin boundaries in lineage-committed cells.
