Core Tip

Core tip: It is known that H2O2 can promote tumorigenesis. Here, we used H2O2 as a premalignant and malignant agent to induce proliferation and malignant transformation in quiescent rat liver oval cell line WB-F344. Multistage carcinogenic processes provide the basis for interrupting and reversing precancerous changes; therefore, reversing precancerous changes is critical for tumor prevention and treatment. The salient and novel findings of the study are that ursolic acid (UA) and oleanolic acid (OA) induced malignantly transformed WB-F344 cell arrest in the G1 phase and apparently inhibited the proliferation of these cells. These results better our understanding of the antitumor effects of OA and UA.
