Abstract
Ginsenoside Rg3 is one of the active ingredients extracted from red ginseng, and it is an effective chemical component of the human body and well known in herbal medicine as a restorative agent. Several studies have shown that Rg3 has a potent anti-tumor effect on various cancer cell lines. However, Rg3-induced apoptosis in B16F10 melanoma cancer cells is not well understood. In the present study, we tested whether ginsenoside Rg3 could induce apoptosis in B16F10 melanoma cells. We found that Rg3 could inhibit B16F10 melanoma cell viability in a dose-dependent manner, but not normal cells, such as EA.hy.926 and NIH3T3 cells. We also found that Rg3 could induce apoptosis in B16F10 melanoma cells using tunnel-staining assay in a dose-dependent manner. Rg3 treatment induces the phosphorylation of p38 and the expression of Bax, but it inhibits the expressions of the phosphorylation of focal adhesion kinase Bcl2 and pro-caspase3. Taken together, our data suggest that Rg3 could be useful as an anti-cancer agent in B16F10 melanoma cells.
