BACKGROUND We hypothesized that cytomegalovirus (CMV) may contribute to the vasculopathy observed in cardiac allograft recipients by impairing the endothelial nitric oxide synthase pathway. We focused on asymmetric dimethylarginine (ADMA, the endogenous inhibitor of nitric oxide synthase) as a potential mediator of the adverse vascular effect of CMV. METHODS AND RESULTS Heart transplant recip...

D ecreased availability of nitric oxide (NO), which contributes to the development of diabetes vascular complications (1), is partially related to asymmetric dimethylarginine (ADMA). ADMA is an endogenous NO synthase inhibitor (2) and a competitive inhibitor of cellular L-arginine uptake (3). ADMA has been associated with atherosclerosis in nondiabetic populations (4) and with diabetic nephropa...

OBJECTIVE Increasing evidence suggested that endoplasmic reticulum (ER) stress contributes to insulin resistance, which plays an important role in the development of type 2 diabetes mellitus (T2DM). Accumulation of endogenous nitric oxide synthase (NOS) inhibitor, asymmetric dimethylarginine (ADMA), is associated with insulin resistance, T2DM, and diabetic cardiovascular complications, although...

PURPOSE Asymmetric dimethylarginine (ADMA), an endogenous competitive inhibitor of nitric oxide synthase, is associated with impaired endothelial dysfunction, such as chronic heart failure, hypertension, diabetes, and pulmonary hypertension. The effects of ADMA on cell proliferation, reactive oxygen species (ROS) production, cell permeability, intercellular adhesion molecule-1 (ICAM-1), and tig...

Bile duct ligation (BDL)-treated rats exhibit cholestasis, increased systemic oxidative stress, and liver fibrosis, which ultimately lead to liver cirrhosis. Asymmetric dimethylarginine (ADMA) is a competitive inhibitor of nitric oxide synthase that can decrease the synthesis of nitric oxide. BDL rats have higher plasma and hepatic ADMA levels, which may be due to increased hepatic protein argi...

It is encouraging to observe that a search for publications on "asymmetric dimethylarginine (ADMA)" in PubMed, as updated on June 2016, yielded >2500 items, 24 years after a splendid paper published by Vallance et al in which the authors proposed that ADMA accumulation could be a cardiovascular risk factor in chronic kidney diseases. ADMA is the endogenous inhibitor of nitric oxide synthase and...

Both hypertension and type 2 diabetes mellitus are common and there are no reliable markers either to predict their development or complications. High fat diet and carbohydrate-rich diet enhance serum asymmetrical dimethylarginine (ADMA) levels, an endogenous inhibitor of nitric oxide synthesis. ADMA levels are elevated in patients with hypertension, poor control of hyperglycemia, diabetic micr...

To the Editor: We read with great interest the article “Correlations of DDAH1 Transcript Variants With Human Endothelial Asymmetric Dimethylarginine Metabolizing Activity”1 by Sun and colleagues, which deals with the relationship between the activity of asymmetric dimethylarginine (ADMA; an endogenous nitric oxide synthase inhibitor) and its degradation enzyme (dimethylarginine dimethylaminohyd...
