Caffeine-induced modulation of the lethal action of X rays on Chinese hamster V79 cells.

Abstract

Caffeine-mediated enhancement of the killing of V79 cells by 220-kV X rays at various times in the cell cycle was compared with that of HeLa cells by measuring (i) the dependence of cell survival on the duration of treatment with 5-10 mM caffeine, (ii) the effect of caffeine treatment on the X-ray dose-survival curve, and (iii) the loss of sensitivity to… (More)
