title: Mouse spermatogonia exposed to a high, multiply fractionated dose of a cancer chemotherapeutic drug: mutation analysis by electrophoresis.
abstract: Male mice of the DBA/2J strain were injected with procarbazine at a dose of 200 mg/kg body weight twice weekly until an accumulated dose of 2400 mg/kg was reached. A concurrent control group, injected only with the vehicle (saline) was also established. Most of the treated animals died as a result of exposure and all survivors became temporarily sterile. After regaining fertility the few survivors were repeatedly mated with C57BL/6J females over several weeks time to generate a population of F1 animals. The parental animals and the F1 were subsequently analyzed by electrophoresis for the occurrence of newly arisen mutations of spermatogonial origin. A mutation in the gene Pep-3 was found.
