Dose-dependent response to repeated cisplatin induction. (a) Experimental scheme. Cisplatin was injected repeatedly at a different dose. (b) Dose-dependent BUN increase in repeated cisplatin-induced nephropathy. (c) Dose-dependent kidney weight reduction in repeated cisplatin-induced nephropathy. (d) Histological analysis of the kidney. PAS staining, Masson’s trichrome, and immunostaining of megalin and kim-1. (e, f, g) Quantification of the tubular injury score, fibrosis score, and the number of kim-1 + tubules. (h) Quantitative PCR of whole kidneys for the representative markers of mature tubules (Lrp2), fibrosis (Col1a1 and Tgfb1), and inflammation (Tnfa, Adgre1, and Ccl2). Data are the mean ± SE. *P < 0.05, †P < 0.05 vs other groups. Scale bar = 100 μm.
