Mitochondrial enzymes involved in energy transformation are organized into multiprotein complexes that channel the reaction intermediates for efficient ATP production. Three of mammalian urea cycle enzymes: N-acetylglutamate synthase (NAGS), carbamylphosphate synthetase 1 (CPS1), and ornithine transcarbamylase (OTC) reside mitochondria. Urea is required to convert ammonia protect brain from tox...
Acute cytotoxicity (lactate dehydrogenase release) of trichloroethylene (TRI), S-(1,2-dichlorovinyl)glutathione (DCVG), and S-(1,2-dichlorovinyl)-L-cysteine (DCVC) in freshly isolated renal cortical cells and hepatocytes from male and female rats was evaluated to test the hypothesis that the assay provides a valid indicator of sex- and tissue-dependent differences in sensitivity to TRI and its ...
Amyloid-beta peptide (Abeta) is believed to be a central player in the Alzheimer disease (AD) pathogenesis. However, its mechanisms of toxicity to the central nervous system are unknown. To explore this area, investigators have recently focused on Abeta-induced cellular dysfunction. Extensive research has been conducted to investigate Abeta monomers and oligomers, and these multiple facets have...
Objective(s): Aluminum phosphide (AlP) is commonly used pesticide which could cause poisoning mainly through the induction of oxidative stress. The present study aimed to evaluate the effects of nano-curcumin and curcumin on the oxidant and antioxidant system in the liver mitochondria using AIP-induced toxicity model.Materials and Methods: In this study, 36 male albino Wistar rats were ra...
The aim of the present study was to show the abilities of captopril as a thiol ACEi (angiotensin converting enzyme inhibitor), on mitochondria toxicity due to paraquat. Mitochondrial isolation from rat liver was divided into 4 groups. Group 1 was considered as control, group 2 received paraquat (5 mM), group 3 received captopril (0.08 mM) and group 4 received paraquat (5 mM)+captopril (0.08 mM)...
One cause of amyotrophic lateral sclerosis (ALS) is mutation in ubiquitously expressed copper/zinc superoxide dismutase (SOD1), but the mechanism of toxicity to motor neurons is unknown. Multiple disease-causing mutants, but not wild-type SOD1, are now demonstrated to be recruited to mitochondria, but only in affected tissues. This is independent of the copper chaperone for SOD1 and dismutase a...
Recent studies suggest that the toxicity of familial amyotrophic lateral sclerosis mutant Cu, Zn superoxide dismutase (SOD1) arises from its selective recruitment to mitochondria. Here we demonstrate that each of 12 different familial ALS-mutant SOD1s with widely differing biophysical properties are associated with mitochondria of motoneuronal cells to a much greater extent than wild-type SOD1,...
