Angiotensin type 1a receptor (AT1aR), angiotensin type 1b receptor (AT1bR), and androgen receptor (AR) mRNA expression in the kidney cortex and medulla from placebo-treated and E2-treated control and intrauterine growth restricted (IUGR) rats at 13.5 months of age. Cortical AT1aR mRNA expression (A), medullary AT1aR mRNA expression (B), cortical AT1bR mRNA expression (C), medullary AT1bR mRNA expression (D), cortical AR mRNA expression (E), and medullary AR mRNA expression (F), in placebo-treated and E2-treated control and IUGR, (n= 5-6/group). Data are expressed as fold changes relative to the mean expression level of the placebo-treated control, which is arbitrarily defined as 1. *P<0.05 vs. placebo-treated control; †P<0.05 vs. placebo-treated IUGR; ‡ P<0.05 vs. E2-treated control; § P<0.05 vs. all groups. P<0.05 denotes significance. Data values represent mean±SEM.
