WebFeb 19, 2014 · Increased p53 and PUMA levels in the Ctcf-null telencephalon. Both the Foxg1Cre and NestinCre models of CTCF loss exhibit increased levels of apoptosis, although the timing of onset differs between the two mutants. To investigate the molecular mechanism responsible for neuronal cell death due to CTCF loss, we assessed …
WebNov 8, 2010 · Thus, the suppressive effect of p53 on BORIS isoforms may be due, at least in part, to upregulation of CTCF . In summary, p53 effects, CTCF binding, and DNA methylation provide three interdependent mechanisms for the complete suppression of BORIS isoforms expression in somatic cells, as a means of avoiding BORIS competition … WebJan 10, 2003 · CTCF then acts through ARF, a direct transcriptional target, to activate p53 and its downstream target, p21. Direct interaction of CTCF with the promoter of p27 results in transcriptional activation (C.-F.Q., unpublished observations), a function that would synergize with down-regulation of MYC, a transcriptional repressor of p27 ( 36 ).
