Serum Fgf23 levels and cardiac Fgf23 expression are elevated in Hyp and kl/kl mice. (A) Increased serum C-term Fgf23 levels in both Hyp and kl/kl mice as compared to respective wild-type mice. (B) Elevation of intact Fgf23 concentrations in the serum of Hyp and kl/kl mice than in respective control mice. (C) Fgf23 mRNA levels are increased in cardiac tissue of both mouse lines demonstrated by quantitative real-time PCR after normalization to Gapdh. (D) Representative immunoblot and respective quantification show the elevation of Fgf23 protein levels in total heart lysates of Hyp and kl/kl animals (Gapdh served as loading control). Values are presented as mean ± SEM; numbers in each bar graph represent the n-values used for the respective measurement; *P < 0.05, **P < 0.01, ****P < 0.0001.
