Abstract:
Accumulation of mutations and chromosomal aberrations is one of the hallmarks of cancer cells. This enhanced genetic instability is fueled by defects in the genome maintenance mechanisms including DNA repair and cell cycle checkpoint pathways. Here, we discuss the emerging roles of the mammalian Chk1 and Chk2 kinases as key signal transducers within the complex network of genome integrity checkpoints, as candidate tumor suppressors disrupted in sporadic as well as some hereditary malignancies and as potential targets of new anticancer therapies.

Inhibition of Cdk Activity
M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
