conclusions we discovered a consistent reduction of serum ace levels by two oral antiviral monotherapies, entecavir and telbivudine. serum ace levels were negatively correlated with egfrs in telbivudine treated patients. objectives we aimed to investigate changes in serum protein abundances associated with renal function in response to antiviral treatments. materials and methods primarily, a tr...

AIMS Angiotensin-converting enzyme (ACE), which metabolizes many peptides and plays a key role in blood pressure regulation and vascular remodeling, is expressed as a type-1 membrane glycoprotein on the surface of different cells, including endothelial cells of the heart. We hypothesized that the local conformation and, therefore, the properties of heart ACE could differ from lung ACE due to di...

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...
