Sodium/hydrogen exchanger 8 (NHE8) expression in human colorectal mucosa in controls (CT) and UC patients (UC). A: NHE8 immunofluorescence (IF) in the colorectal region of normal human subjects (left) and UC patients (right). Red fluorescence represents NHE8 protein; DAPI was used to stain the nuclei (blue). The scale bar in IF images is 50 μm. B: NHE8 protein expression comparison between controls and UC patients. NHE8 protein expression is calculated by the ratio of optical density of NHE8 over GAPDH. Data are mean ± SE from 44 samples (18 for control group, 26 for UC group). *P < 0.05 for UC patients vs. controls.
