Dose-dependent effects of ethanolic extract of asiasari radix (ARE) on the growth of G361 melanoma cells and HaCaT keratinocytes. a Microscopic images of G361 and HaCaT cells after 24 h of incubation with 0, 62.5, 125, 250, 500, and 1000 μg/ml of ARE. Total cellular protein was stained with SRB; data shown are representative of three independent experiments. b Dose-dependent effects of ARE (200, 400, 600, 800 and 1000 μg/ml) on the growth rate of G361 and HaCaT cells were tested at 24 h after the treatment, using the SRB assay. Data represent the mean ± SEM (n = 4). The significant difference between HaCaT and G361 cells were marked as * (p < 0.05); nt, non-treated control
