From: Low potassium disrupt intestinal barrier and result in bacterial translocation
Low potassium disrupt the tight junctions in Caco-2 cell. A Western blot analysis of Claudin-1, Claudin-2 and Occludin in Caco-2 cells treated with low potassium at various concentrations for 48 h or 0.1 mM potassium for the indicated time periods. β-Actin was used as a loading control. B Densitometric anaysis of the blots showing the ratios of Claudin-1, Claudin-2 and Occludin to β-actin. C Immunofluorescence staining of Claudin-1, Claudin-2 and Occludin in Caco-2 cell (original magnification ×800, all sections). Values are means ± SD, n = 3. *p < 0.05, **p < 0.01 vs. the control group
