E‐cadherin expression enhances glucose transporter (GLUT) expression. (a) Total RNA extracted from AGS and EC96 gastric cancer cells were subjected to RT‐PCR with GLUT1‐, GLUT3‐, and GLUT4‐specific primers. Averages of three independent experiments with error bars are presented. *P < 0.05; **P < 0.01; ***P < 0.001. (b) Cells were treated with triptolide (200 nM) for 24 h, and the lysates were then subjected to immunoblot analysis for E‐cadherin, GLUT1, and β‐actin. Band intensity was normalized to β‐actin.
