Genistein Prevents Apoptosis and Oxidative Stress Induced by Methylglyoxal in Endothelial Cells.

Glycolytic overload promotes accumulation of the highly reactive dicarbonyl compounds, resulting in harmful conditions called dicarbonyl stress. Methylglyoxal (MG) is a highly reactive dicarbonyl species and its accumulation plays a crucial pathophysiological role in diabetes and its vascular complications. MG cytotoxicity is mediated by reactive oxygen species (ROS) generation, a key event underlying the intracellular signaling pathways leading to inflammation and apoptosis.

Morphological, Gene, and Hormonal Changes in Gonads and In-Creased Micrococcal Nuclease Accessibility of Sperm Chromatin Induced by Mercury.

Mercury is one of the most dangerous environmental pollutants. In this work, we analysed the effects of exposure of to 1, 10 and 100 pM HgCl for 24 h on the gonadal morphology and on the expression level of three stress genes: , and . In this tissue we also evaluated the level of steroidogenic enzymes 3β-HSD and 17β-HSD and the expression of PL protein genes.
