Expression of renal AT
R. Renal expression of type 2 angiotensin receptor protein and mRNA in kidneys from rats fed a control and low-protein diet during pregnancy (A & C) and in non-pregnant rats at different stages of the oestrus cycle (B & D). Data is presented as mean ± SEM (n = 6-8 per group). Data was analysed by one or two-way ANOVA as described in the methods section. Representative western blots are shown. Protein expression of the AT2R was significantly lower in kidneys from low-protein fed rats across all gestational ages. As this was an interaction of gestational age × diet (p < 0.05), no symbols are shown.
