Title: The effect of caffeine on survival of UV-irradiated diploid yeast strains of different sensitivities. Author: Kiefer J. Journal: Mutat Res; 1975 Dec; 30(3):317-26. PubMed ID: 1105164. Abstract: The action of caffeine post-treatment after UV exposure in three strains of diploid yeast has been studied. The addition of the drug to the plating medium reduced survival in all cases. Higher colony-forming abilities were found in all strains when the UV dose had been split into two fractions with an interval of about 6 h. Caffeine added to the incubation medium between dose fractions did not interfere with this process in the wild type but suppressed split-dose sparing completely in two sensitive strains.[Abstract] [Full Text] [Related] [New Search]
