Fibrosis markers in UUO-induced kidney injury.
A, immunoblotting for E-cadherin expression and Smad2 phosphorylation in the wild-type and PAR2−/− kidneys at day 7 post-UUO. B, histogram showing the relative expression of E-cadherin in the UUO-induced kidney injury in each group (mean ± S.E.; *, p < 0.05, n = 8). C, mRNA expression assessed by quantitative real-time PCR for Ctgf and D, Tgfb1 in the UUO-induced kidney injury at day 7 in the wild-type and PAR2−/− mice (fold-change over contralateral kidney, mean ± S.E.; *, p < 0.05; **, p < 0.01, n = 8).
