From: Ginsenoside G-Rh2 synergizes with SMI-4a in anti-melanoma activity through autophagic cell death
SMI-4a enhanced apoptosis in melanoma cells in vitro. a Flow cytometry analysis of A375 cells and G361 cells stained with Annexin V-FITC/PI after SMI-4a treatment, DMSO was used as negative control. b Cells were treated with SMI-4a (1 μM) for 48 h and caspase 3/7 activity was tested by the Caspase-Glo® 3/7 Assay kit. The results are expressed as the mean ± SEM. *p < 0.05 and ***p < 0.001
