WebCTCF loops were shown to be highly dynamic, based on the very transient and cell cycle-dependent binding time of the protein, ... The depletion of CTCF in cancer cells was performed by electroporation-mediated delivery of an esiRNA pool targeting the human CTCF transcript (Figure 2, Table S5). WebHere, the data with FDR < 0.05 are considered as the CTCF-mediated chromatin loops. In addition, we focus on whether single CTCF site can form loop anchor. ChIA-PET data consists of a combination of two anchors, which can result in a single anchor corresponding to multiple other anchors. Therefore, when extracting location data of anchors ...
