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). WebFeb 28, 2024 · The transcription factor E2F, the principal target of the RB pathway, plays central roles in cell proliferation by activating a repertoire of growth-related genes. Consistent with this, overexpression of E2F1, an activator type of E2F family members, in quiescent cells induces progression into S phase [ 4 ].
