DNA damage-specific control of cell death by cryptochrome in p53-mutant ras-transformed cells.

Abstract excerpt

The main feedback loop driving circadian rhythm in mice is controlled, in part, by the genes encoding the cryptochromes Cry1 and Cry2. Targeted mutation of both Cry1 and Cry2 delay the early onset of tumor formation in p53-null mutant mice. Furthermore, Ras-transformed p53- and Cry-null mouse skin fibroblasts are more sensitive than p53 mutants to apoptotic cell death initiated by agents that activate either the...
