    Abstract:
    The preliminary anti-cancer activity of Naringenin (Nar) has been proven in several cancers. However, the therapeutic activity of Nar on gastric cancer SGC-7901 cell line is not yet well understood. The aim of the present study was to investigate the effect and mechanisms of Nar on proliferation, apoptosis, migration, and invasion of SGC-7901 cells. In this in vitro study, SGC-7901 cells were treated with Nar at serial concentrations. Our data showed that Nar efficiently inhibited SGC-7901 cell proliferation in a time- and concentration-dependent manner, as well as downregulated proliferating cell nuclear antigen (PCNA) levels in a concentration-dependent manner. Meanwhile, the cell migration and invasion also dramatically decreased after Nar incubation, and the expressions of MMP2 and MMP9 were significantly downregulated. In addition, a strong proapoptotic effect was observed in the SGC-7901 cells after Nar treatment. Apoptosis-related proteins Bax and cleaved caspase-3 were up-regulated, whereas Bcl-2 and Survivin were downregulated. After administration with Nar, we found that phosphorylation of AKT was inhibited, and this inhibitory action could be mildly enhanced by the combination treatment of Nar and AKT inhibitor LY294002. In conclusion, our study confirmed that Nar could inhibit SGC-7901cell proliferation, migration, and invasion as well as induces apoptosis, and Nar might provide a new potential therapeutic strategy for treating gastric cancer.
