Fig. 3From: Emodin inhibits invasion and migration of hepatocellular carcinoma cells via regulating autophagy-mediated degradation of snail and β-cateninEffects of emodin on invasion and migration potential of HepG2 cells. A The scratch assay was used to investigate the effect of emodin on the wound healing ability at 0, 24, and 36 h. The wound healing rate was calculated as (the width of initial wound - the width of remaining wound) / the width of initial wound. (magnification, × 50). B Cells were treated with various concentrations of emodin for 48 h, transwell migration and transwell invasion assays were performed on treated cells. (magnification, × 100). Each experiment was repeated at least three times; representative images were shown. Data were expressed as mean ± SD. * P < 0.05Back to article page
