Cell biology: A BID for the pathway
Michael B. Kastan1
Abstract
Cells have many ways of coping with damage to their DNA, but how are these all coordinated? It seems that BID — a regulator of programmed cell death — stands at the crossroads of several damage-response pathways.
Exposure to DNA-damaging agents can cause mutations, developmental abnormalities or cancer, and cells have developed numerous ways to minimize these effects. Such mechanisms include cell-cycle checkpoints to prohibit damaged cells from dividing while the cell deals with the damage; processes to repair the DNA; and programmed cell death (apoptosis).
