ACE2 counteracts angiotensin II by converting it to potentially protective angiotensin 1-7. (nature.com)
We estimated ACE activity using the angiotensin II:I ratio (ACE-S) and estimated systemic alt-RAS activation using the ratio of alt-RAS axis metabolites to PRA-S (ALT-S).

ZO-2 and ZO-3 are ubiquitously expressed within epithelial tight junctions, and unlike ZO-1, which is also expressed at cell junctions of cardiac myocytes, ZO-2 is not expressed in nonepithelial tissue. (thermofisher.com)
However, numerous studies have demonstrated that light to moderate alcohol consumption (ie, 1-2 drinks per d or 3-9 drinks per wk) decreases the risk of cardiac events such as myocardial infarction. (medscape.com)

Estrogen deficiency and chronic alcohol consumption may have a synergistic and deleterious effect on bone tissue. (bvsalud.org)

However, although these mechanisms may play a role in selected patients, most evidence in the literature indicates that the effects of alcohol on the myocardium are independent of these factors and that the effect is a direct toxic result of ethanol or its metabolites. (medscape.com)
Although the mechanisms of action for these two classes of drugs differ, both classes have beneficial effects on the vasculature. (radcliffecardiology.com)
