mRNA expression of (A) transforming growth factor β (Tgfb1), (B) platelet-derived growth factor (Pdgfb), and (C) connective tissue growth factor (Ccn2) of control, diabetic and dapagliflozin treated diabetic rats (D+DAPA). (D) mRNA expression of Serpine1 (also known as plasminogen activator inhibitor-1). (E) Protein level of α-smooth muscle actin (α-SMA). Proteins were normalized to total protein Ponceau S staining as loading control. (F) mRNA expression of fibronectin (Fn). mRNA expressions were normalized to Rn18S mRNA expression. Bars indicate means±SDs and data were analyzed by one-way ANOVA with Holm-Sidak multiple comparisons test (n = 6/group) *p<0.05 vs. Control, **p<0.01 vs. Control, ***p<0.001 vs. Control, §p<0.05 vs. Diabetic, §§p<0.01 vs. Diabetic, §§§p<0.001 vs. Diabetic.
