Abstract
In the commonly accepted paradigm for control of the mammalian cell cycle, sequential cyclin-dependent kinase (CDK) and cyclin activities drive the orderly transition from G1 to S phase. However, recent studies using different technological approaches and examining a broad range of cancer cell types are challenging this established paradigm. An alternative model is evolving in which cell cycles utilize different drivers and take different trajectories through the G1/S transition. We are discovering that cancer cells in particular can adapt their drivers and trajectories, which has important implications for antiproliferative therapies. These studies have helped to refine an understanding of how CDK inhibition impinges on proliferation and have significance for understanding fundamental features of cell biology and cancer.
期刊介绍:
Trends in Cell Biology stands as a prominent review journal in molecular and cell biology. Monthly review articles track the current breadth and depth of research in cell biology, reporting on emerging developments and integrating various methods, disciplines, and principles. Beyond Reviews, the journal features Opinion articles that follow trends, offer innovative ideas, and provide insights into the implications of new developments, suggesting future directions. All articles are commissioned from leading scientists and undergo rigorous peer-review to ensure balance and accuracy.
