Figure 2.
Protection against renal I/R injury by a FXR agonist. Mice were injected i.p. with 6-ECDCA before I/R injury. At 24 h after I/R, kidney, serum and urine samples were collected for measurements of (A) FXR target gene expression in kidney, (B) BUN in serum, (C) creatinine in serum. (D) Representative images showing HE staining on renal sections from (a) sham, (b) I/R, (c) I/R + ECDCA and (d) sham + ECDCA groups (scale bar 50 μm). (E) Representative images showing Kim1 immunostaining in renal sections from (a) sham, (b) I/R, (c) I/R + ECDCA and (d) sham + ECDCA groups (scale bar 50 μm). Kim1 is specifically localized in the proximal tubules. (F) Quantitative analysis of tubular injury scores. n = 6 mice/group. (G) Quantitative analysis of Kim1 positive staining per high power field. n = 6 mice/group. Data are means ± SEM, one-way ANOVA with Bonferroni’s test. *p < 0.05.
