WebFeb 2, 2010 · The components of the RB-pathway, i.e., RB, E2F, D-type cyclins, Cdk4/6, p16Ink4a (CDKN2a) and their functional interactions, are depicted in the diagram. Genetic and epigenetic alternations in the RB-pathway are consistently detected in the majority of sporadic human cancers, and these defects are summarized in the purple box at the … WebHowever, how CtIP executes this function remains to be elucidated. Here we show that in NIH 3T3 cells the expression of CtIP is regulated by the E2F/RB pathway during late G 1 and S phases. The presence of wild-type CtIP, but not the E157K mutant form, which failed to interact with RB, enhanced its own promoter activity. ionescu photography
