WebHowever, the potential contribution of CTCF to HOX cluster silencing and the underlying mechanism have not been established. Here, we demonstrate that the HOXA locus is organized by CTCF into chromatin loops and that CTCF depletion causes significantly enhanced activation of HOXA3 to - A7, -A9 to - A11 , and - A13 in response to retinoic … WebJun 12, 2024 · CTCF binding profile and expression pattern of HOXA genes in human foreskin fibroblasts. (A) Occupancy of CTCF, H3K4me3 and H3K27me3 versus transcriptional activity across HOXA locus in BJ cells, and also in HFF cells (B).
