A p53-independent damage-sensing mechanism that functions as a checkpoint at the G1/S transition in Chinese hamster ovary cells

Lee, Hoyun; Hamlin, Joyce L.; Larner, James M.

In response to a moderate dose of radiation, asynchronous mammalian cell populations rapidly and transiently down-regulate the rate of DNA synthesis to ≈50% of preirradiation values. We show here that only half of the reduction in overall replication rate can be accounted for by direct inhibition of...
