Wagging the dogma; tissue-specific cell cycle control in the mouse embryo

Cell. 2004 Sep 3;118(5):535-8. doi: 10.1016/j.cell.2004.08.013.


The family of cyclin-dependent kinases (Cdks) lies at the core of the machinery that drives the cell division cycle. Studies in cultured mammalian cells have provided insight into the cellular functions of many Cdks. Recent Cdk and cyclin knockouts in the mouse show that the functions of G1 cell cycle regulatory genes are often essential only in specific cell types, pointing to our limited understanding of tissue-specific expression, redundancy, and compensating mechanisms in the Cdk network.
