Recent studies hint that Ginsenoside is involved in cancer prevention and treatment. In this study, we investigated the effect of Ginsenoside Rh2 on drug resistance in human colorectal carcinoma (CRC) cells and its mechanism. The resistance reversion effect of Ginsenoside Rh2 in CRC cells was analyzed using CCK-8 assay. After treating with Ginsenoside Rh2, the cell cycle distribution and cellular apoptosis were analyzed by flow cytometry,cell migration was determined by transwell migration assay, the expression of drug-resistance genes and proteins were evaluated using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot, respectively. Ginsenoside Rh2 could enhance the cytotoxicity of 5-FU in drug-resistant CRC cells (LoVo/5-FU and HCT-8/5-FU). Treatment with Ginsenoside Rh2 could result in an increase of cell numbers in G0/G1 phase accompanied with a decrease in S-phase, and induced cellular apoptosis in drug-resistant CRC cells. In addition, the migration process and EMT process of drug-resistant CRCcells were suppressed by treatment of Ginsenoside Rh2. Compared to control group, expression of drug-resistance genes, such as MRP1, MDR1, LRP and GST, were negatively correlated to Ginsenoside Rh2. All these results indicated that Ginsenoside Rh2 could effectively reverse drug resistance in human colorectal carcinoma cell and its mechanism involved the prevention of cellular proliferation and migration, the promotion of cellular apoptosis and the alteration of drug-resistance genes, which suggested that Ginsenoside Rh2 may act as a promising candidate for drug resistance in human colorectal carcinoma chemotherapy.
