The present study was carried out to investigate the molecular mechanism of arsenic-induced mitochondrial oxidative damage and its relation to biogenesis in rat brain. Chronic sodium arsenite (25 ppm, orally) administration for 12 weeks decreased mitochondrial complexes activities and mRNA expression of selective complexes subunits. The expression of mitochondrial biogenesis regulator PGC-1α, and...
Arsenic (As) is a worldwide naturally occurring metalloid. Human chronic exposure to inorganic As compounds (iAs), which are at the top of hazardous substances (ATSDR, 2013), is associated with different diseases including cancer and non- cancerous diseases. The neurotoxic effects of iAs and its methylated metabolites have been demonstrated in exposed populations and experimental models. Impaired...
