(a) Representative western blot and densitometric analysis for the inducible isoform of nitric oxide synthase (iNOS) in aortic segments from WKY and SHR; mouse macrophages were used for iNOS positive controls (C+). (b) Quantitative RT-PCR assessment of iNOS mRNA expression in the same segments. Results are expressed as the relative expression of protein or mRNA in SHR compared to WKY. ANOVA (one-way): ^*P<0.05. The number of animals are indicated in parentheses. WKY, Wistar Kyoto rat; SHR, spontaneously hypertensive rat.
