BTXA inactivates the phosphorylation of PI3K and Akt. (A) The protein expression of p-PI3K, PI3K, p-Akt and Akt was examined by western blot analysis. (B) BTXA notably suppressed the ratio of p-PI3K/PI3K. (C) BTXA notably suppressed the ratio of p-Akt/Akt. β-actin was used as an internal control. Dotted line separation represents whether or not fibroblasts were treated with TGF-β1. Data are shown as the means ± SD, n=3. *P<0.05 and **P<0.01 vs. control without TGF-β1; ^^P<0.01 vs. control with TGF-β1.
