P-235: No Association of Endothelial Nitric Oxide Synthase (eNOS) -786T/C Polymorphism with Unexplained Recurrent Abortion in Iranian Women
Background: This is a case-control study to determine the relationship between endothelial nitric oxide synthase (eNOS) gene -786T/C polymorphism in women with unexplaiend recurrent abortion in comparison with healty women.Materials and Methods: 95 women with history of at least 2 unexplaiend recurrent abortion in the reproductive age range 20-35 years as patients group and 95 healty women (age...
متن کاملGating NO release from nitric oxide synthase.
We have investigated the kinetics of NO escape from Geobacillus stearothermophilus nitric oxide synthase (gsNOS). Previous work indicated that NO release was gated at position 223 in mammalian enzymes; our kinetics experiments include mutants at that position along with measurements on the wild type enzyme. Employing stopped-flow UV-vis methods, reactions were triggered by mixing a reduced enzy...
متن کاملNO synthase? Generation of nitric oxide in plants
It has now become well accepted that nitric oxide (NO) has a key role to play in the signalling that takes place in plant cells. However, the sources of NO in plants has been hard to determine and there is considerable debate as to exactly how NO is made by plant cells. In animals nitric oxide synthase (NOS) enzymes have been characterised and such data has been used to inform the studies which...
متن کاملDietary nitrite restores NO homeostasis and is cardioprotective in endothelial nitric oxide synthase-deficient mice.
Endothelial production of nitric oxide (NO) is critical for vascular homeostasis. Nitrite and nitrate are formed endogenously by the stepwise oxidation of NO and have, for years, been regarded as inactive degradation products. As a result, both anions are routinely used as surrogate markers of NO production, with nitrite as a more sensitive marker. However, both nitrite and nitrate are derived ...
متن کاملNo association of the Asp298 variant of the endothelial nitric oxide synthase gene with preeclampsia.
BACKGROUND Preeclampsia, the most common serious complication of pregnancy, is characterized by vasoconstriction, dysfunction of the vascular endothelium, and hypertension. Unidentified genetic factors and impaired nitric oxide (NO)-mediated vasodilation are thought to contribute to the development of the syndrome. Polymorphisms of the endothelial nitric oxide synthase (eNOS) gene affect NO pro...
