Angiotensin-(1-7)-angiotensin-converting enzyme 2 attenuates reactive oxygen species formation to angiotensin II within the cell nucleus
Hypertension 2010 Jan;55(1):166-71.PMID:19948986DOI:10.1161/HYPERTENSIONAHA.109.141622.
The angiotensin (Ang) type 1 receptor (AT(1)R) is highly expressed on renal nuclei and stimulates reactive oxygen species (ROS). It is not known whether other functional components of the Ang system regulate the nuclear Ang II-AT(1)R ROS pathway. Therefore, we examined the expression of Ang receptors in nuclei isolated from the kidneys of young adult (1.5 years) and older adult (3.0 to 5.0 years) sheep. Binding studies in renal nuclei revealed the AT(2)R as the predominant receptor subtype ( approximately 80%) in young sheep, with the Ang-(1-7) (AT(7)R; Mas protein) and AT(1)R antagonists competing for the remaining sites. Conversely, in older sheep, the AT(1)R accounted for approximately 85% of nuclear sites, whereas the Ang type 2 receptor and AT(7)R subtypes comprise approximately 20% of remaining sites. Ang II increased nuclear ROS to a greater extent in older (97+/-22%; n=6) versus young animals (7+/-2%; P=0.01; n=4), and this was abolished by an AT(1)R antagonist. The AT(7)R antagonist D-Ala(7)-Ang-(1-7) increased ROS formation to Ang II by approximately 2-fold (174+/-5% versus 97+/-22%; P<0.05) in older adults. Immunoblots of renal nuclei revealed protein bands for the AT(7)R and Ang-converting enzyme 2 (ACE2), which metabolizes Ang II to Ang-(1-7). The ACE2 inhibitor MLN4760 also exacerbated the Ang II-dependent formation of ROS (156+/-15%) and abolished the generation of Ang-(1-7) from Ang II. We conclude that an ACE2-Ang-(1-7)-AT(7)R pathway modulates Ang II-dependent ROS formation within the nucleus, providing a unique protective mechanism against oxidative stress and cell damage.
Primary role of angiotensin-converting enzyme-2 in cardiac production of angiotensin-(1-7) in transgenic Ren-2 hypertensive rats
Am J Physiol Heart Circ Physiol 2007 Jun;292(6):H3019-24.PMID:17308000DOI:10.1152/ajpheart.01198.2006.
Angiotensin-converting enzyme-2 (ACE2) converts angiotensin II (ANG II) to angiotensin-(1-7) [ANG-(1-7)], and this enzyme may serve as a key regulatory juncture in various tissues. Although the heart expresses ACE2, the extent that the enzyme participates in the cardiac processing of ANG II and ANG-(1-7) is equivocal. Therefore, we utilized the Langendorff preparation to characterize the ACE2 pathway in isolated hearts from male normotensive Sprague-Dawley [Tg((-))] and hypertensive [mRen2]27 [Tg((+))] rats. During a 60-min recirculation period with 10 nM ANG II, the presence of ANG-(1-7) was assessed in the cardiac effluent. ANG-(1-7) generation from ANG II was similar in both the normal and hypertensive hearts [Tg((-)): 510 +/- 55 pM, n=20 vs. Tg((+)): 497 +/- 63 pM, n=14] with peak levels occurring at 30 min after administration of the peptide. ACE2 inhibition (MLN-4760, 1 microM) significantly reduced ANG-(1-7) production by 83% (57 +/- 19 pM, P<0.01, n=7) in the Tg((+)) rats, whereas the inhibitor had no significant effect in the Tg((-)) rats (285 +/- 53 pM, P>0.05, n=10). ACE2 activity was found in the effluent of perfused Tg((-)) and Tg((+)) hearts, and it was highly associated with ACE2 protein expression (R=0.78). This study is the first demonstration for a direct role of ACE2 in the metabolism of cardiac ANG II in the hypertrophic heart of hypertensive rats. We conclude that predominant expression of cardiac ACE2 activity in the Tg((+)) may be a compensatory response to the extensive cardiac remodeling in this strain.
