Effect of irradiation on unscheduled DNA synthesis induced by 4-nitroquinoline in tracheal epithelium of rats

Description

Unscheduled DNA synthesis (UDS) was determined in rat epithelium by autoradiographic techniques to determine the influence of prior irradiation on the ability of the cells to repair mutagenic damage induced by 4-nitroquionoline (4NQO). UDS was stimulated by in vitro exposure to 4NPO. However, prior whole-body irradiation of rats with either 50 or 300 rad did not alter the UDS induced by 4NQO. The results of this study do not support the hypothesis that irradiation can induce DNA repair enzymes in respiratory tract epithelium. 5 references, 3 figures
