Nitrosative stress
Jan 21, 2022 · Oxidative/nitrosative stress (ROS/RNS) and inflammation are the critical pathological processes of MDD. The results of this study contribute towards a better understanding of the familial association of depressive disorder, and for the first time have demonstrated a positive correlation in neutrophil ROS/RNS, plasma nitrite, and serum cortisol ... Nov 11, 1998 · This nitrosative threat has been studied extensively because of its carcinogenic potential . The focus, however, has been on nitrosation of exogenous amines, when the principle intracellular target is thiols (6, 23, 37). In other words, anaerobic respiration may be viewed as a nitrosative stress characterized by formation of NO and SNO.

Iron deficiency (anemia) (ID(A)) is associated with oxidative stress, but its role in the induction of nitrosative stress is largely unclear. Moreover, oral as well as intravenous (iv) iron preparations used for the treatment of ID(A) may also induce oxidative and/or nitrosative stress. Oxidative/nitrosative stress is a “privilege” of aerobic organisms. It consists by endogenous and exogenous factors. Most frequently, it is described by the production of ROS/RNS. Oxidative/nitrosative stress is a deleterious process which can be an important mediator of damage to cell structures, including lipids and membranes, proteins ...
Shared metabolic and immune-inflammatory, oxidative and nitrosative stress pathways in the metabolic syndrome and mood disorders. Prog. Neuropsychopharmacol. Biol. Psychiatry (2017) A. Diaz et al. Metformin improves in vivo and in vitro B cell function in individuals with obesity and Type-2 Diabetes.Therefore, our findings suggest that P2X7R and iNOS may exert nitrosative stress in a positive feedback manner under inflammatory conditions. Nrf2 plays a role in the regulation of cellular redox homeostasis . Under nitrosative stress, Nrf2 sequestered by Keap1 is transported to the nucleus and promotes ARE-related gene expressions.It can inhibit proinflammatory responses and oxidative stress in different models of disease. In the present study, we investigated the effect of SB on lipopolysaccharide (LPS)-induced depression-like behaviors, neuroinflammatory response, and oxido-nitrosative stress in the hippocampus and prefrontal cortex in C57BL6/J mice.Neuroprotection in acute stroke: targeting excitotoxicity, oxidative and nitrosative stress, and inflammation Lancet Neurol. 2016 Jul;15(8):869-881. doi: 10.1016/S1474-4422(16)00114-9.

PE is characterized by increased S-nitrosylated (SNO) proteins and nitrosative stress. We recently showed that mice lacking S-nitrosoglutathione reductase (GSNOR-/-mice ... ….

A major pathological effect of diabetes mellitus is the chronic oxidative–nitrosative stress, and the recently reported carbonyl 9 and methylglyoxal stress 10, which drives many of the secondary ...X-ray-triggered nitrite (NO 2 −) is used for hypoxic prostate cancer therapy by inhibiting protective autophagy and inducing lethal nitrosative stress based on ZIF-82-PVP. After entering tumor cells, the released 2-nitroimidazole ligands capture low-energy electrons derived from X-rays to produce NO 2 − , and the Zn 2+ inhibits the ...
Increased catalase activity might reflect a compensatory mechanism directed to attenuate the impact of OS and nitrosative stress. Thus, increased catalase activity supports the hypothesis that OS is increased in depression. However, some clinical studies have reported a contradictory decrease in catalase activity during depressive episodes.Oxidative/nitrosative stress is a “privilege” of aerobic organisms.
