Rhbg expression in normal and acid-loaded diet in C and CD-Rhbg/Rhcg-KO mice. A: Rhbg expression in CD-Rhbg/Rhcg-KO mice fed a normal and acid-loaded diet. There was no detectable change in Rhbg expression in the DCT or CNT. B: Rhbg immunolabel in C mice fed a normal and acid-loaded diet. Rhbg expression in the cortex and OM was significantly greater in acid-loaded than in normal diet mice. Basolateral Rhbg immunolabel in OMCD principal cells (arrowheads) was increased in acid-loaded C mice relative to immunolabel in normal diet C mice. Intercalated cell (arrows) basolateral Rhbg immunolabel was unchanged.
