Western blot analysis for TGF-β1 and type IV collagen. (A) Representative bands of western blot for TGF-β1 and type IV collagen are shown. (B) The densitometric ratio of TGF-β1 to β-actin was increased in the diabetic control group versus the control LETO group. TGF-β1 protein was recovered by FA treatment in the diabetic control group. (C) The densitometric ratio of type IV collagen to β-actin was increased in the diabetic control group versus the control LETO group. Type IV collagen protein was restored by FA treatment in the diabetic control group. CON, control group; DM, diabetic group; FA, ferulic acid treated diabetic group. ^*P < 0.05 compared with CON.
