Effects of tranilast on the Akt/β-catenin signaling pathway.

Western blot analysis was performed on human peritoneal mesothelial cells (HPMCs) exposed to transforming growth factor-beta 1 (TGF-β1) in the presence or absence of tranilast (100 μM) for 24 hours. Quantification is relative to the control and normalized to β-actin expression. TGF-β1 increased phosphorylated-Akt (p-Akt)/Akt protein expression ratio and β-catenin protein expression. Tranilast reversed these changes. n = 4 per group.

C, control; OD, optical density; T, HPMCs with TGF-β1 treatment; T + TR, HPMCs with TGF-β1 and tranilast cotreatment.

*P < 0.05 compared to the C group, ^#P < 0.05 compared to the T group.
