From: Effect of sampling time on somatic and germ cell mutations induced by acrylamide in gpt delta mice
The gpt mutant frequencies in the testes, sperm and lung treated with ENU. ENU was administered daily by intraperitoneal administration for 5 days and the gpt MFs were estimated at at day 31 (5 + 26d) (open bars) and day 77 (5 + 72d) (dark bars). For ENU-treated groups, mutant frequency is shown, instead of mutation frequency. The error bar represents the standard deviation. * P < 0.05, ** P < 0.01, significantly different from vehicle control or between sampling points (Student or Welch t-test)
