Relative expression of canonical and non-canonical Wnt target genes upon unilateral ureter obstruction. We isolated total RNA from whole kidneys of sham-operated control mice and of mice which had been challenged with UUO and analyzed expression of target genes of canonical Wnt signaling (Axin2, Wisp2, Trp53, and Ccnd1, graphs A-D) and of non-canonical Wnt target genes (CamK2a, Plcb1, Daam1, and Ptk7, graphs E-H). Data is presented as means ± SD. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001, n.s. no significance; UUO, unilateral ureteral obstruction.
