Literature evidence Rg5 was proved to induce caspase-dependent apoptosis via the activation of the extrinsic death receptor and intrinsic mitochondrial signaling pathways.

Gene or Protein evidence As shown in the results from western blot analysis, Rg5 increased expression of p53, p21(WAF1/CIP1) and p15(INK4B) and decreased expression of Cyclin D1, Cyclin E2 and CDK4.
Target pathways Further studies showed that Rg5 in a dose-dependent manner induced apoptosis and autophagy through the inhibition of the PI3K/Akt signaling pathway as indicated by the reduced phosphorylation level of PI3K and Akt. Rg5 was proved to induce caspase-dependent apoptosis via the activation of the extrinsic death receptor and intrinsic mitochondrial signaling pathways. These results indicate that Rg5 stimulated cell apoptosis and cell cycle arrest at G0/G1 phase via regulation of cell cycle-associated proteins in MCF-7 cells. Ginsenoside Rg5 induces apoptosis and autophagy via the inhibition of the PI3K/Akt pathway against breast cancer in a mouse model.
IC50 NA
Potency Taken together, Rg5 could be a novel and promising clinical antitumor drug targeting breast cancer.
Cell line/ mice model BALB/c nude mouse model of human breast cancer, MCF-7
Additional information  Rg5 promotes breast cancer cell apoptosis in a multi-path manner with higher potency compared to 20(S)-ginsenoside Rg3 (Rg3) in MCF-7 (HER2-/ER+) and MDA-MB-453 (HER2+/ER-) human breast cancer cell lines, and this suggests that Rg5 might be an effective natural new material in improving breast cancer.
