Figure 5. Reverse transcriptase–PCR gel electrophoresis images of vascular endothelial–cadherin/vimentin/Twist/glyceraldehyde 3-phosphate dehydrogenase mRNA expression in EA.hy926 cells. The effect of rapamycin on the gene expression of vascular endothelial (VE)-cadherin, vimentin, and Twist. (a, scratch group; b₁, 10 ng/ml rapamycin group; b₂, 100 ng/ml rapamycin group; b₃, 1,000 ng/ml rapamycin group; c, no-scratch group).
