Abstract α-Aminoadipic acid (Aaa) is an intermediate product in the Lys catabolism, on saccharopine pathway. Since content was increased by various abiotic stress factors affecting redox environment, a glutathione-dependent regulation of Aaa metabolism assumed which not tested earlier. The effect modified size and state glutathione pool (reduced + oxidised, GSH GSSG) related amino transcript le...

The in vitro and in vivo electrochemical detection of the reduced form of glutathione (L-γ-glutamyl-L-cysteinyl-glycine, GSH) using boron doped diamond (BDD) microelectrode for potential application in the assessment of cancerous tumors is presented. Accurate calibration curve for the determination of GSH could be obtained by the in vitro electrochemical measurements. Additionally, it was shown...

Ascorbate (AsA)-glutathione (GSH) cycle metabolism has been regarded as the most important defense mechanism for the resistance of plants under stress. In this study the influence of salicylic acid (SA) was studied on ascorbate-glutathione pathway, S-assimilation, photosynthesis and growth of mustard (Brassica juncea L.) plants subjected to 100 mM NaCl. Treatment of SA (0.5 mM) alleviated the n...

The precise mechanisms underlying skeletal muscle damage in Duchenne muscular dystrophy (DMD) remain ill-defined. Functional ischemia during muscle activation, with subsequent reperfusion during rest, has been documented. Therefore, one possibility is the presence of increased oxidative stress. We applied a model of acute hindlimb ischemia/reperfusion (I/R) in mdx mice (genetic homolog of DMD) ...

Endothelial dysfunction due to vascular inflammation and oxidative stress critically contributes to the etiology of atherosclerosis. The intracellular redox environment plays a key role in regulating endothelial cell function and is intimately linked to cellular thiol status, including and foremost glutathione (GSH). In the present study we investigated whether and how the dietary flavonoid, qu...

The potassium efflux system, Kef, protects bacteria against the detrimental effects of electrophilic compounds via acidification of the cytoplasm. Kef is inhibited by glutathione (GSH) but activated by glutathione-S-conjugates (GS-X) formed in the presence of electrophiles. GSH and GS-X bind to overlapping sites on Kef, which are located in a cytosolic regulatory domain. The central paradox of ...

The celiac disease is an autoimmune gastrointestinal disorder caused by gluten from wheat, rye or barley. In genetically predisposed persons, gluten induces the immune-mediated inflammation of small intestinal mucosa. Histological lesions include intraepithelial lymphocytosis, crypt hypertrophy and villous atrophy, resulting in malabsorption of micro- and macronutrients. The only treatment for ...

OBJECTIVE To study the effect of Sorbaria Sorbifolia extract on anti-oxidative activities in rats with precancerosis induced by diethylnitrosamine. METHODS Sorbaria sorbifolia was perfused into stomach of rats with DEN-induced precancerosis, then the biochemical indexes were investigated. The activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), and the concentrations of ...

The anticancer drug cyclophosphamide induces granulosa cell apoptosis and is detoxified by glutathione (GSH) conjugation. We previously showed that both cyclophosphamide treatment and GSH depletion induced granulosa cell apoptosis in rats, but the role of GSH in apoptosis in human ovarian cells has not been studied. Using the COV434 human granulosa cell line, we tested the hypotheses that (1) G...

The 1958 symposium of the Biochemical Society consists of seven papers given by British biochemists on areas of glutathione (GSH) chemistry and biochemistry. The topics presented may be listed briefly: chemistry of GSH, techniques for determining GSH, oxidation-reduction systems associated with GSH in plant tissues, GSH in animal tissues, and neural tissues, and in lens, and finally the effect ...
