Figure 2. Renal mRNA expression of angiotensin receptors A: type 1a (At1ar) and B: type 2 (At2r) in young and aged mice (n=7-8). Brain mRNA expression of D:At1ar and E:At2r in young and aged mice (n=7-8). Mesenteric artery mRNA expression of G:At1ar and H:At2r in young and aged mice (n=6-7). Effect of aging on At1ar:At2r ratio in C: kidney, F: brain and I: mesenteric artery (n=6-8). All data are mean ± S.E.M. *P<0.05 vs young, Student’s unpaired t-test.
