DDAH says NO to ADMA.
Endothelium-derived nitric oxide (NO) is vasoprotective, as it enhances endothelial cell survival and proliferation, inhibits the excessive proliferation of vascular smooth muscle cells, and suppresses the adhesion of platelets and inflammatory cells to the vessel wall.1 Substantial evidence from preclinical studies and human research indicates that impairment of the endothelial NO synthase (NO...
متن کاملThe ADMA/DDAH pathway regulates VEGF-mediated angiogenesis.
OBJECTIVE Asymmetrical dimethylarginine (ADMA) is a nitric oxide synthase (NOS) inhibitor and cardiovascular risk factor associated with angiogenic disorders. Enzymes metabolising ADMA, dimethylarginine dimethylaminohydrolases (DDAH) promote angiogenesis, but the mechanisms are not clear. We hypothesized that ADMA/DDAH modifies endothelial responses to vascular endothelial growth factor (VEGF) ...
متن کاملPDE5 says NO to cGMP
A protease inhibitor unsticks cells AI-1 is unique among protease inhibitors because it binds to the matrix protein vitronectin (VN). PAI-1 binding blocks VN's binding site for the cell surface receptor uPAR and for integrin family members. Czekay et al. (page 781) now show that PAI-1 is also able to detach cells through a less direct approach. Unlike the direct competition method, PAI-1 also d...
متن کاملInfluence of ezetimibe on ADMA-DDAH-NO pathway in rat liver subjected to partial ischemia followed by global reperfusion.
BACKGROUND We evaluated effect of ezetimibe on selected parameters determining NO level in rat liver subjected to ischemia reperfusion (IR). METHODS Rats received ezetimibe (5 mg/kg) (groups E0 and EIR) or saline solution (groups C0 and CIR) intragastrically for 21 days. Then, the livers of CIR and EIR underwent ischemia (60 min) and reperfusion (4 h). Blood samples were obtained before surge...
متن کاملFolic acid says NO to vascular diseases.
OBJECTIVES The possible link between folic acid or folate and tetrahydrobiopterin (H(4)B), vitamin C, polyunsaturated fatty acids (PUFAs), and nitric oxide (NO), which may explain the beneficial actions of these nutrients in various vascular conditions, was investigated. METHODS The literature pertaining to the actions of folic acid/folate, H(4)B, vitamin C, PUFAs, and NO was reviewed. RESU...
