Figure Lengend Snippet: ARG2 may be a potential target of cisplatin-induced AKI. (A–C) ARG2 protein and mRNA expressions in the kidneys of cisplatin-induced AKI mice. (D) Representative images of immunohistochemistry staining of ARG2 in cisplatin-induced AKI mice kidneys. The red arrows indicate deeper ARG2-positive staining of renal tubules. Scale, 20×, 100 μm, 40×, 50 μm. (E) Representative images of the immunofluorescence colocalization of CD31, F4/80, LTL, PNA, and DBA with ARG2 in the kidney of cisplatin-induced AKI mice. The following specific markers were used: endothelial, CD31; macrophage, F4/80; proximal tubule, lotus tetragonolobus lectin (LTL); distal tubule, peanut agglutinin (PNA); and collecting duct, dolichos biflorus agglutinin (DBA). The white arrows indicate positive tubules with colocalization of ARG2 and specific tubular markers. Scale, 50 μm. (F and G) ARG2 protein expression in primary tubular epithelial cells treated by cisplatin. (H–K) Renal function and renal tissue injury of ARG2 KO and WT mice administrated with cisplatin were assessed by SCr, BUN, and tubular injury score. The red arrows showed the vacuolar degeneration, tubular necrosis, cast formation, and tubular dilation of renal tubules. (L and M) The HO-1 protein expression was evaluated by western blotting in ARG2 KO and WT mice administrated with cisplatin. * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001. mean ± SD, n = 6.
