NO followed by the activation of sGC and the production of
cGMP. To identify the molecule in Fgarlic that exhibits antihypertensive
effect in SHR, an inhibitor of sGC was pretreated
and then fed Fgarlic. Decreases in SBP and right ventricular hypertrophy induced by Fgarlic were attenuated by the pretreatment with the sGC inhibitor. Additionally, the expressions of PKG and eNOS protein were highly up-regulated, and aortic cGMP content was increased in aortic tissues from SHR fed Fgarlic compared to those in aortic tissues from SHR fed water.
These findings suggest that nitrite in Fgarlic is the functional
molecule and exerts anti-hypertensive effect through sGCcGMP-
PKG pathway in SHR.
