Renal tubular injury induced by IR is less in trpa1^−/− mice. (A) Representative images of periodic acid-Schiff (PAS) staining in renal sections obtained from the two genotypes of mice subjected to two different treatments. The magnification of each panel was 400×. (B) Tubular injury score was calculated according to the percentage of injured area of tubular cross sections. The scores system is described in the methods. Data in each group are mean ± SEM from 6 mice. ** p < 0.01 versus the sham group in each genotype; ^# p < 0.05 versus the IR group of WT mice.
