Patulin (PAT) is a mycotoxin produced by certain species of Penicillium and Aspergillus. The aim of this study was to assess PAT-induced DNA damage and to clarify the mechanisms, using human hepatoma G2 (HepG2) cells. PAT caused significant increase of DNA migration in single cell gel electrophoresis assay. To elucidate the role of glutathione (GSH), the intracellular GSH level was modulated by pre-treatment...
Patulin (PAT), a mycotoxin produced by certain species of Penicillium, Aspergillus and Byssochlamys, is mainly found in ripe apple and apple products. In our present study, a significant increase of the micronuclei frequency induced by PAT was found in human hepatoma HepG2 cells. To elucidate the role of glutathione (GSH) in the effect, the intracellular GSH level was modulated by pre-treatment with...
Oxidative stress plays an important role during inflammatory diseases and antioxidant administration to diminish oxidative stress may arrest inflammatory processes. Boron has been implicated to modulate certain inflammatory mediators and regulate inflammatory processes. Here we investigated the role of the tripeptide glutathione (GSH) in modulating the effects of boric acid (BA) on lipopolysaccharide...
Trichloroethylene (TCE) is an environmental and industrial pollutant whose hepatotoxicity has been demonstrated in experimental animals. However, the mechanisms of the effects, in particular those related to its genotoxicity in humans, are not well understood. The aim of this study was to assess the genotoxic effects of TCE and to identify and clarify the mechanisms, using human hepatoma HepG2 cells...
