Expression of ACE (A), ACE2 (B), and AT1 receptor (C) in NTG, Gαq-TG, and Gαq-TG+olmesartan hearts. ACE isoform expression was normalized to actin expression and is expressed relative to NTG (set at 1). AT1 receptor was normalized to GAPDH and is expressed relative to NTG (set at 1). Data are the mean ± SE obtained from 6 mice for each group. Mice at the age of 32 weeks were used.
