abstractText | As a part of the ILSI-HESI Alternative to Carcinogenicity Testing (ACT) program, we performed a 26-week carcinogenetic study of nonmutagenic drug, ampicillin (ABPC) in Tg-rasH2 mice. ABPC was given to Tg-rasH2 mice (0, 350, 1000, 3000 mg/kg, p.o.) and Non-Tg mice (0, 3000 mg/kg, p.o.) daily for 26 weeks. As a positive control, a single dose of MNU was administered once to Tg-rasH2 mice (75 mg/kg, i.p.). In this study, Tg-rasH2 mice did not demonstrate any increases in tumor development in response to ABPC. Thus, ABPC had no carcinogenicity in the 26-week carcinogenesis study in Tg-rasH2 mice or in a 2-year carcinogenesis study in B6C3F1 mice. |
