Expression of Acox1 and Oil red O staining of the kidneys in patients with AKI. (A–C) Representative micrographs show Oil red O staining and renal Acox1 expression in healthy controls and patients with AKI, and the percentage of positive area was quantified. (D–E) The positive percentage of Acox1 was quantified according to acute and chronic injury scores. Data are expressed as the means ± SDs for each group. Differences between the two groups were assessed with a two-tailed Student’s t-test. For the three groups, statistical differences were analyzed using ANOVA followed by Bonferroni and Kruskal-Wallis tests for normally and non-parametrically distributed variables, respectively. *P < 0.05 versus 0 group.
