Effect of empagliflozin administration on type I and type IV collagen expression in CsA-treated rats. On the left. Representative photomicrographs of type I and type IV collagen expression in control, control + Empa, CsA, and CsA + empagliflozin-treated rats (original magnification X20). Type I collagen showed an increased tubulo-interstitial staining in CsA-treated rats, while type IV collagen was increased mainly in the intraglomerular area in CsA-treated rats, as compared to control and control + Empa-treated rats. Empagliflozin administration prevented the increase of both type I and type IV collagen in CsA-treated rats. On the right. Quantification of type I and type IV collagen proteins in renal tubulo-interstitial and glomerular area, respectively, in the different groups of rats. Data are means ± SEM. §: p < 0.01.
