WebThe G1/S transition is a stage in the cell cycle at the boundary between the G1 phase, in which the cell grows, and the S phase, during which DNA is replicated. [1] It is governed … WebHere, we show that, in budding yeast, the G1 inhibitor Whi5 is a key environmental indicator and plays a crucial role in coordinating cell growth and division. We found that, under a variety of nutrient and stress conditions, Whi5 amount in G1 is proportional to the cell's doubling time in the environment, which in turn influences the timing ...
WebNov 1, 2013 · Europe PMC is an archive of life sciences journal literature. The result of CDK6 overexpression is a remarkable scenario in which the presence or absence of a single gene, p16 INK4a, determines whether cell proliferation is inhibited or accelerated.Only if p16 INK4a is present can the feedback loop operate and normal growth be secured.
