Inhibition of GBM migration and epithelial–mesenchymal transition by urolithin A and urolithin B. U251 cells were incubated with urolithins for 24 h. Migration ability was determined by a wound healing assay and visualized using a digital camera following treatment with urolithin A (A,B) and B (C,D). Transmigration ability was determined using a transwell assay and visualized using a microscope following treatment with urolithin A (E,F). Vimentin, N-cadherin, and β-catenin protein expression levels were determined by Western blotting (G,H). Each bar represents the mean ± standard error of the mean (n = 3). * p < 0.05 compared with the control group.
