2019年1月14日 · CDK—the master regulator of the cell cycle—sends signals to control all major steps of cell division. CDK is activated at each stage of the cell cycle by binding of stage-specific cyclins.
Keeping track of time: The fundamentals of cellular clocks
In this review, we explore the common themes and core design principles of cellular clocks, giving special consideration to the challenges associated with building timers from biochemical components. We also outline how evolution has coopted time to increase the reliability of a diverse range of biological systems.
The circadian clock and cell cycle: Interconnected biological …
The circadian clock controls multiple aspects of the cell cycle, conferring gating mechanisms at key checkpoints of the cell cycle to ensure fidelity in DNA replication and cell division. How this is accomplished is not fully understood.
Time-keeping and decision-making in the cell cycle - PMC
In this review, we uncover some secrets of cell cycle regulation by mathematical modelling of increasingly more complex molecular regulatory networks of cell cycle ‘clocks’ and ‘switches’. Keywords: cell cycle regulation, cell cycle checkpoints, cyclin-dependent kinases, mathematical models, limit cycles, bistable switches
Researchers Build Diagram of Cell Cycle Clock
For the first time, researchers at the Whitehead Institute have mapped the complete circuit of one of life's most fundamental processes—the cell cycle, which tells cells when to divide. This network diagram describes the genetic switches and connections that form the circuit common to a process found in all living organisms, from bacteria to ...
How the cell cycle clock ticks - PubMed
2019年1月15日 · But how can the same CDK induce different events when activated at different times during the cell cycle? This question, which has bewildered cell cycle researchers for decades, now has a sufficiently clear mechanistic answer.
A central clock runs the cell division cycle - News
2016年5月4日 · This proves that cyclin expression, and not global oscillations in gene expression, really is essential for moving the cell cycle forward. In other words, there is a central clock in the middle of the factory.
Molecular Links between the Circadian Clock and the Cell Cycle
2020年5月29日 · Here we review the molecular organization of the circadian clock and the cell cycle, as well as the reciprocal interaction between the circadian clock and the cell cycle in normal and in cancer cells.
