Abstract

Oxysophoridine (OSR) is a major active alkaloid extracted from Sophoraalopecuroides L. The aim of the present study was to investigate the induction of the apoptotic effects of OSR on colorectal cancer cells in vivo and in vitro. The results of the MTT and colony formation assays demonstrated that the proliferation of HCT116 cells was inhibited by OSR in vitro. The characteristics of cellular apoptosis in OSR‑treated HCT116 cells were analyzed by Hoechst 33258 staining. It was also observed that the expression of caspase‑3, B‑cell lymphoma‑2 (Bcl‑2) associated X protein (Bax) and cytochrome c increased significantly upon OSR treatment. However, the expression of Bcl‑2 and poly ADP‑ribose polymerase‑1 (PARP‑1) was downregulated in OSR‑treated cells compared with untreated cells. The in vivo experiments identified that OSR significantly inhibited the growth of the transplanted mouse CT26 tumor tissue, upregulated the expression of caspase‑3, Bax and cytochrome c and downregulated the expression of Bcl‑2 and PARP‑1, as detected by reverse transcription‑quantitative polymerase chain reaction and western blotting. It may be concluded that OSR significantly induced apoptotic effects on colorectal cancer cells in vivo and in vitro, and that its mechanism may be associated with the Bcl‑2/Bax/caspase‑3 signaling pathway.
