Figure 5 Role of norepinephrine and epinephrine in regulating activation of the renin-angiotensin system after aortic constriction. The renal renin messenger ribonucleic acid (mRNA) level was significantly increased in the banded control mice compared with the sham-operated mice, but not in the banded Dbh–/– mice. *p < 0.001 for sham operation control group vs. TAC control group; p = NS for sham operation Dbh–/– group vs. TAC Dbh–/– group. Sham operation: n = 6 in control group and n = 4 in Dbh–/– group; TAC: n = 4 in control group and n = 6 in Dbh–/– group.
