The regulatory network for the G1/S transition in Saccharomyces cerevisiae promotes the understanding of cancer developmental mechanisms

Abstract

The G1/S transition is crucial for regulating the initiation of cell division and is highly conserved across eukaryotes. This phase of the cell cycle involves intricate transcriptional controls that are essential for understanding cell proliferation dynamics. The G1/S transition integrates diverse intracellular and extracellular signals, including growth factors and cell sizes. Saccharomyces cerevisiae, an important model organism, plays an integral role in unveiling the regulatory mechanisms of the G1/S transition. Recent studies on the G1/S transition in both yeast and vertebrates have demonstrated a direct correlation between dysregulation of the G1/S transition and the development of cancer. This review explores the G1/S transition regulatory network and its association with cancer formation, providing a theoretical foundation for future research in fundamental cell cycle dynamics and cancer.
