Effect of GBE on HIF-1α and TGF-β1 expression in rat renal tissues. The expression of HIF-1α and TGF-β1 was detected using immunohistochemical staining and quantified. (A and C) Representative images of immunohistochemically stained renal tissue sections. Magnification, x400. HIF-1α and TGF-β1 protein expression was primarily observed in the renal tubular epithelial cells. (B and D) Quantitative analysis of HIF-1α and TGF-β1 proteins expression levels in renal tissues, respectively. Data are presented as the mean ± standard deviation. n=9. *P<0.05 vs. CDDP group, #P<0.05 vs. CDDP + GBE group. GBE, Ginkgo biloba extract; SB, SB203580; HIF-1α, hypoxia inducible factor-1α.
