    AbstractPrevious reports have confirmed that crude saponins (ginsenosides) in Panax ginseng have a preventive effect on chemotherapy-induced intestinal injury. However, the protective effects and possible mechanisms of ginsenoside Re (G-Re, a maker saponin in ginseng) against chemotherapy-induced intestinal damage have not been thoroughly studied. In this work, a series of experiments in vivo and in vitro on the intestinal toxicity caused by cisplatin have been designed to verify the improvement effect of G-Re, focusing on the levels of Wnt3a and [Formula: see text]-catenin. Mice were intragastric with G-Re for 10 days, and intestinal injury was induced by intraperitoneal administration of cisplatin at a dose of 20 mg/kg. Histopathology, gastrointestinal digestive enzyme activities, inflammatory cytokines, and oxidative status were evaluated to investigate the protective effect. Furthermore, in IEC-6 cells, G-Re statistically reverses cisplatin-induced oxidative damage and cytotoxicity. The TUNEL and Hoechst 33258 staining demonstrated that G-Re possesses protective effects in cisplatin-induced apoptosis. Additionally, pretreatment with G-Re significantly alleviated the apoptosis via inhibition of over-expressions of B-associated X (Bax), as well as the caspase family members, such as caspase 3 and 9, respectively, in vivo and in vitro. Notably, western blotting results showed that G-Re treatment decreased Wnt3a, Glycogen synthase kinase [Formula: see text] (GSK-[Formula: see text]), and [Formula: see text]-catenin expression, suggesting that nuclear accumulation of [Formula: see text]-catenin was attenuated, thereby inhibiting the activation of GSK-[Formula: see text]-dependent Wnt/[Formula: see text]-catenin signaling, which was consistent with our expected results. Therefore, the above evidence suggested that G-Re may be a candidate drug for the treatment of intestinal injury.
