WebFeb 10, 2024 · CCCTC-binding factor (CTCF) is critical to three-dimensional genome organization. Upon differentiation, CTCF insulates active and repressed genes within … WebHox genes have been shown to be regulated by antisense transcription as well as the topological organization of the locus and the contact to remote enhancers (22, 23), but so far only for the HOXA cluster has a role cohesin and CTCF at the barrier element been shown .
WebFeb 17, 2024 · HOTTIP facilitates the posterior HOXA TAD to drive a homeotic transcription program partly by binding to annotated CBSs (Luo et al., 2024), suggesting that HOTTIP can regulate CTCF boundary activity, perhaps by interacting with CTCF complexes. We performed chromatin isolation by RNA purification in conjunction with liquid … WebHox-CTCF link across the Bilateria. On the basis of these findings, we propose the existence of a Hox-CTCF kernel as principal orga-nizer of bilaterian body plans. Such a kernel could explain (i) the formation of Hox clusters in Bilateria, (ii) the diversity of bilaterian body plans, and (iii) the uniqueness and time of onset of the Cam-
WebAug 23, 2024 · HOX gene dysregulation is a common feature of acute myeloid leukemia (AML). The molecular mechanisms underlying aberrant HOX gene expression and associated AML pathogenesis remain unclear.

Webdeletion of a CTCF site within the Hox clusters in mouse ES cells disrupts a topological boundary, resulting in activation of previously silent Hox genes. (Narendra et al. 2015). The importance of maintaining these bound-aries is made clear in experiments deleting a CTCF-asso-ciated TAD boundary near the limb enhancers normally

CTCF binds together strands of DNA, thus forming chromatin loops, and anchors DNA to cellular structures like the nuclear lamina. It also defines the boundaries between active and heterochromatic DNA. Since the 3D structure of DNA influences the regulation of genes, CTCF's activity influences the expression of genes.
