Figure 3. Mesenteric resistance artery AT2R mRNA declines with age in female mice only. Total RNA was extracted from mesenteric resistance arteries, and qRT/PCR was performed to quantify angiotensin II type 2 [AT2R, (A and B)] and type 1b [AT1BR, (C and D)] receptor mRNA expression. N = 5-6/group. Differences were assessed via one-way ANOVA with Tukey post hoc testing where appropriate. Data are means ± SEM, *P < 0.05; **P < 0.01.
