The role of nitric oxide synthases and nitrotyrosine in retinoblastoma [PDF]
Cancer, 2005 AbstractBACKGROUNDTo investigate the potential involvement of the nitric oxide (NO) pathway in retinoblastoma, the authors correlated immunoreactivity for endothelial nitric oxide synthase (eNOS), inducible nitric oxide synthase (iNOS), and nitrotyrosine (NT) with the degree of tumor invasiveness in retinoblastoma.METHODSeNOS, iNOS, and NT reactivity ...

Biological Reviews, EarlyView.ABSTRACT The environmental conditions organisms experience during early development can have powerful and sustained effects on morphology, physiology, behaviour, and performance. Such developmental effects can influence reproductive success, survival, and life‐history strategies and can be transmitted across generations (i.e.

Chemistry – A European Journal, EarlyView.We report a cellular membrane‐targeted europium(III) probe, Eu.Chol, that enables selective, time‐resolved detection of peroxynitrite (ONOO−) at the cell membrane interface. Eu.Chol demonstrates efficient incorporation into liposomes and Jurkat cells, with minimal response to H2O2, establishing a modular platform for subcellular ONOO− sensing ...

Is Nitrotyrosine Generated in Human Erythrocytes in Circulation?
Biological and Pharmaceutical Bulletin, 2000 Nitrotyrosine is considered a stable biomarker of reactive nitrogen species, including nitrogen dioxide (NO2) and peroxynitrous acid (ONOOH) in biomaterials. There are inconsistent observations on the detection of free and protein-associated nitrotyrosine in normal human plasma. Human erythrocytes, differentiated from erythrocyte precursor cells in the

Quantification of 3-nitrotyrosine in biological tissues and fluids: generating valid results by eliminating artifactual formation [PDF]
, 2000 Reactive nitrogen species such as peroxynitrite can nitrate specific amino acids, whether free or protein bound, and 3-nitrotyrosine is believed to be one marker of this reaction.
