Rb/e2f pathway

WebJan 1, 2014 · The Rb/E2F pathway has also been shown to be involved in macromolecule synthesis; specifically E2F activates the genes involved in DNA synthesis such as TS, DHFR, and TK (Trimarchi & Lees, 2002). Other review articles cover these aspects in greater depth (Blanchet et al., 2009, Fritz and Fajas, 2010, Nicolay and Dyson, 2013). WebSep 26, 2024 · Previously, we showed that the Rb-E2F pathway network functions as a bistable switch, converting graded and transient serum growth signals into an all-or-none E2F activity, which directly correlates with the all-or-none outcome of quiescence exit (Aguda, 2015, Yao et al., 2008).
