Unlike the ubiquitous angiotensin-converting enzyme (ACE), the ACE-related carboxypeptidase 2 (ACE 2) is predominantly expressed in the heart, kidney, and testis. ACE 2 degrades angiotensin (Ang) II to Ang (1-7) and Ang I to Ang (1-9). We investigated the expression of ACE and ACE 2 in a rodent model of type 2 diabetes. ACE and ACE 2 were measured in kidney and heart from 8-week-old no diabetic...
Angiotensin I-converting enzyme (ACE) hydrolyzes numerous peptides and is a critical participant in blood pressure regulation and vascular remodeling. Elevated tissue ACE levels are associated with increased risk for cardiovascular and respiratory disorders. Blood ACE concentrations are determined by proteolytic cleavage of ACE from the endothelial cell surface, a process that remains incomplet...
Background: Several studies investigated the association of ACE I/D polymorphism with the risk and severity of COVID-19 infection. However, the information in each of the published studies is limited, and the results were inconsistent or even contradictory. Accordingly, this meta-analysis evaluated the association between the ACE I/D polymorphism and COVID-19 susceptibility and severity. Metho...
background: recurrent pregnancy loss (rpl) defined by two or more failed pregnancies before 20 weeks of gestation. several factors play a role in rpl including thrombophilic conditions which can be influenced by gene polymorphisms. plasminogen activator inhibitor-1 (pai-1) and angiotensin converting enzyme (ace) genes are closely related to fibrinolytic process, embryonic development and pregna...
OBJECTIVE Angiotensin-converting enzyme (ACE) is present in many cell types of atherosclerotic lesions. This study determined whether ACE activity in endothelial and smooth muscle cells (SMCs), 2 major resident cell types of the aorta, contributes to hypercholesterolemia-induced atherosclerosis. APPROACH AND RESULTS All study mice were in low-density lipoprotein receptor(-/-) background. To d...
Angiotensin converting enzyme (ACE) is a zinc-containing dipeptidase that converts angiotensin I to angiotensin II, a powerful vasoconstrictor and smooth muscle growth factor. ACE activity has been shown to be dynamically regulated by hormones, ACE inhibitors, and endothelial cell growth state. To study how ACE expression is regulated, we isolated and sequenced the bovine ACE gene using both AC...
Background: Coronary artery disease (CAD) is currently the leading cause of death among people around the world. The main cause of CAD is atherosclerosis or vascular arrest. In the etiology of this disease, various factors, including genetic factors, are involved. In this study, the effect of angiotensin converting enzyme (ACE) as a risk factor was evaluated. Increasing ACE activity by enhancin...
Background & Aim: The most important cause of mortality in developing countries is coronary artery diseases(CAD). From ethiological point of view, CAD is multifactorial. In this study, some involved important factors were evaluated. Patients and Methods: In this cross-sectional study, 94 normal controls and 106 cases with 50% angiographically proved coronary stenosis who had referred to Teh...
آنزیم تبدیل کننده آنژیوتانسین ( ace ( با اثر روی مولکول غیرفعال آنژیوتانسین (angi) i آن را تبدیل به مولکول فعال آنژیوتانسین (angii)ii می نماید. بافتهای اپی تلیومی، اندوتلیومی و نورواپی تلیالی منبع ace هستند. این آنزیم در بافتهایی نظیر ریزپرزهای روده و توبولهای کلیه فراوان است و مقداری از آن نیز درون پلاسما شناور می باشد. در مواردی دیده شده است که استفاده از داروهای دارای سمیت ریوی یا کلیوی، توا...
Angiotensin I-converting enzyme (ACE) inhibitors have been proven to be highly effective and are for the most part the drugs of choice in the treatment and control of hypertension, congestive heart failure, and left ventricular dysfunction. Despite this, questions regarding side effects and compliance with this traditional pharmacological strategy remain. In view of these observations, coupled ...
