Vitamin D Regulates the Expressions of AQP-1 and AQP-4 in Mice Kidneys

Figure 4

The synergistic effects of Vitamin D and inhibiting renin activity on upregulation of AQP-4 expression. (a) Immunohistochemical stain in kidney by AQP-4 antibody. (b) Immunohistochemical stain in renal proximal tubule by AQP-4 antibody. (c, d) The statistic analysis of (a) and (b) by Image J. (e) AQP-4 expressions in renal proximal tubule were detected by immunofluorescence staining. All photographs were shown with a 400-fold magnification. Positive expression was indicated by arrows. Compared with wt group, P<0.05. # Compared with wt group, P<0.05.
