Links between mutant p53 and genomic instability.

Abstract excerpt

The tumor suppressor p53 has long been known to play a central role in maintaining a stable genome in the face of toxic insults through its role in promoting cell-cycle checkpoints, DNA repair, and apoptosis. However, p53 null cells still retain some function of certain checkpoint and repair processes, reducing the genomic changes that otherwise would occur if these mechanisms were absent. Accumulating evidence...
