SPAK inactivation in WNK1+/FHHt mice decreases NCC abundance and phosphorylation below control levels. Upper panel: Representative immunoblots of NCC and phosphorylated NCC-Thr53 performed on the membrane-enriched fractions of the renal cortex of mice of each genotype. Lower panel: Densitometric analysis. NCC abundance and phosphorylation are increased in WNK1+/FHHt mice compared to control mice. NCC abundance and phosphorylation in WNK1+/FHHt:SPAK243A/243A and SPAK242A/243A mice are corrected below the control levels. Number of animals: 4 control, 5 WNK1+/FHHt, 4 WNK1+/FHHt:SPAK243A:243A and 4 SPAK243A:243A male mice. Values are means ± s.e.m. ap < 0.05 vs. controls. bp < 0.05 vs. WNK1+/FHHt. cp < 0.05 vs. SPAK243A/243A-WNK1+/FHHt FHHt (Kruskal-Wallis one-way analysis of variance followed by Mann-Whitney test). Immunoblot images are cropped images. The full-length images can be found in Supplementary Figure S3.
