TRPV1 receptors are involved in protein nitration and Muller cell reaction in the acutely axotomized rat retina
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2010)
We report here the protein expression of TRPV1 receptor in axotomized rat retinas and its possible participation in mechanisms involved in retinal ganglion cell (RGC) death. Adult rats were subjected to unilateral, ...
Two nitrate/nitrite transporters are encoded within the mobilizable plasmid for nitrate respiration of Thermus thermophilus HB8
Thermus thermophilus HB8 can grow anaerobically by using a membrane-bound nitrate reductase to catalyze the reduction of nitrate as a final electron acceptor in respiration. In contrast to other denitrifiers, the nitrite ...
Role of cyclic GMP on inhibition by nitric oxide donors of human eosinophil chemotaxis in vitro
(Nature Publishing GroupLondonInglaterra, 2004)
Rapid and slow modulation of nitrate reductase activity in the red macroalga Gracilaria chilensis (Gracilariales, Rhodophyta): influence of different nitrogen sources
(SPRINGER, 2008)
Nitrate is one of the most important stimuli in nitrate reductase (NR) induction, while ammonium is usually an inhibitor. We evaluated the influence of nitrate, ammonium or urea as nitrogen sources on NR activity of the ...
Conjugated linoleic acid is a preferential substrate for fatty acid nitration
(American Society for Biochemistry and Molecular Biology, 2012-12)
The oxidation and nitration of unsaturated fatty acids by oxides of nitrogen yield electrophilic derivatives that can modulate protein function via post-translational protein modifications. The biological mechanisms ...
Nitrate and nitrite metabolism in ruminant livestock
(Edición del Autor, 2019)
Global methane emissions from livestock have continue to rise in last decade due to the increasing ruminant population and demand for livestock products. Supplementing the diet of ruminants with nitrate (NO3) is an effective ...
Nitric oxide inhibits nitrate reductase activity in wheat leaves
(Elsevier Masson, 2011-02)
Nitrate reductase (NR), a committed enzyme in nitrate assimilation, is involved in the generation of nitric oxide (NO) in plants. In wheat leaf segments exposed to sodium nitroprusside (SNP) or S-nitrosoglutathione (GSNO), ...
Nitrogen effect on gas exchange characteristics, dry matter production and nitrate accumulation of Amaranthus cruentus L.
(2019-01-01)
Among the mineral nutrients, nitrogen stands out as an essential constituent of amino acids, nucleic acids and proteins, as well as being part of the photosynthetic apparatus. The present study aimed to evaluate the responses ...
Protein tyrosine phosphorylation and protein tyrosine nitration in redox signaling
(Mary Ann Liebert Inc, 2008-05-01)
Reversible phosphorylation of protein tyrosine residues by polypeptide growth factor-receptor protein tyrosine kinases is implicated in the control of fundamental cellular processes including the cell cycle, cell adhesion, ...
