Abstract

The present study aimed to investigate the anti-tumor mechanisms of gambogic acid (GA) on NCI-H1993 xenografts in vivo. Non-small cell lung carcinoma NCI-H1993 cells, which harbor a MET gene amplification, were subcutaneously injected into athymic nude mice. The mice were randomly assigned to treatment with 10, 20 or 30 mg/kg GA for 3 weeks. At the end of the efficacy study, all the mice were sacrificed and the tumor tissues were subjected to western blot analysis and immunohistochemical (IHC) staining. GA inhibited NCI‑H1993 xenograft tumor growth in a dose‑dependent manner. Western blot analysis demonstrated that expression of phosphorylated (p)‑MET and its downstream signaling molecules p‑AKT and p‑ERK1/2 were significantly inhibited by GA. IHC analysis of Ki‑67 expression demonstrated that GA treatment resulted in dose‑dependent inhibition of tumor cell proliferation. GA exerted antitumor effects on NCI‑H1993 xenografts in vivo by direct regulation of the MET signaling pathway. Theses antitumor effects were primarily a result of its anti-proliferation function.
