A. Representative blots showing carotid body angiotensin type I receptor (AT1R) and neuronal nitric oxide synthase (nNOS) expression. B. Summary data for AT1R and nNOS expression. AT1R expression was increased in CIH vs. NORM; this difference was not evident in rats treated with losartan (left panel). nNOS expression was decreased in CIH vs. NORM; this decrease was not evident in losartan-treated rats (right panel). *p<0.05 vs. respective control condition.
