摘要

Two parallel and concordant activities characterize cell cycle progression. One is associated with preparation for and execution of DNA replication followed by mitosis ("cell cycle"). Cyclins are the motors of the cell cycle, as they activate the respective CDKs and thereby drive the cell through the sequential phases of the cycle. Their antagonists are CKIs, which inhibit the CDKs stalling the cycle progression. The second type of activities involves anabolic processes that contribute to growth in cell size and mass ("cellular growth"). Constitutive signaling along the mT0R/S6K pathways is the key factor mediating these anabolic processes.1 During unperturbed and balanced growth these two activities are flawlessly coordinated.
