Fig. 2From: A cross-talk between integrin β4 and epidermal growth factor receptor induces gefitinib chemoresistance to gastric cancerIntegrin β4 promotes resistance of gastric cancer cell lines to gefitinib. a The expression of integrin β4 with integrin β4 siRNA or over-expressed vector was assayed by Western blot (n = 4) and real-time PCR (n = 4). b The proliferation of gastric cancer cell lines was assayed by MTT (n = 5). c Apoptosis rate was assayed by flow cytometry (n = 4). *P < 0.05 and **P < 0.01 vs. SCG7901. ##P < 0.01 vs. SGC7901RBack to article page
