Fig. 5From: Phoyunnanin E inhibits migration of non-small cell lung cancer cells via suppression of epithelial-to-mesenchymal transition and integrin αv and integrin β3H460, H292 and A549 cell invasion was examined using transwell invasion assay. After 48 h, the invaded cells were stained with Hoechst 33342 and visualized by fluorescence microscopy (a, c, e). The relative invasion level was calculated as the number of invaded cells of the treatment groups divided by that of the untreated control group (b, d, f). Data are shown as the mean ± SD (n = 3). * P < 0.05 versus non-treated controlBack to article page
