“Caffeine potentiation of BCNU-induced SCEs was also time dependent and was eliminated by a delay of 6 h between BCNU treatment and addition of caffeine.”
“Our results suggest that caffeine potentiates BCNU cytotoxicity and induction of SCEs by a mechanism that is independent of repair of alkylation products, but that may depend on alterations of cellular replication in BCNU-treated cells.”
“The synergistic effect of caffeine on cellular toxicity diminished when caffeine was added 6 to 24 h after treatment of BCNU.”
