The present study aims to investigate the effects of ginsenoside Rg3 combined with oxaliplatin on the proliferation and apoptosis of hepatocellular carcinoma cells and the related mechanism. In this study, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was applied to examine the proliferation rate of hepatocellular carcinoma cell SMMC-7721 with different treatment. Flow cytometry was performed to examine apoptosis rate of hepatocellular carcinoma cells with different treatment. Immunofluorescence and Western blot methods were used to evaluate the expressions of proliferating cell nuclear antigen (PCNA) and cyclin D1 in different groups. We found that ginsenoside Rg3, oxaliplatin or ginsenoside Rg3 + oxaliplatin significantly suppressed the proliferation and promoted the apoptosis of SMMC-7721. Meanwhile, ginsenoside Rg3, oxaliplatin or ginsenoside Rg3 + oxaliplatin also significantly inhibited the expressions of PCNA and cyclin D1. Moreover, compared with ginsenoside Rg3 group and oxaliplatin group, the effect of ginsenoside Rg3 + oxaliplatin was more remarkable. Taken together, cells treated with oxaliplatin+ ginsenoside enhanced the anti-tumor effect and may inhibit the proliferation and promoted apoptosis of hepatocellular carcinoma via regulating the expression of PCNA and cyclin D1.
