Cortical ATR1a mRNA expression (4a), medullary ATR1a mRNA expression (4b), cortical ATR1b mRNA expression (4c), medullary ATR1b mRNA expression (4d), cortical androgen receptor mRNA expression (4e), medullary androgen receptor mRNA expression (4f) in female vehicle-treated control (n=8) and IUGR offspring (n=7) and flutamide-treated control (n=9) and IUGR offspring (n=8). Data are expressed as fold changes relative to the mean expression level of the vehicle-treated control rats that were arbitrarily defined as 1. *P<0.05 versus vehicle-treated control. †P<0.05 versus vehicle-treated IUGR.
