Methylglyoxal induces glycation and oxidative stress in Saccharomyces cerevisiae

Purpose Hyperglycemia causes abnormal accumulation of methylglyoxal (MGO) and concomitant DNA, protein glycation. These pathophysiological changes further leads to diabetic complications. Yeast Saccharomyces cerevisiae is one of the best model to study MGO-induced glycation modifications. The aim of the present study was to investigate the effect of MGO on protein, DNA glycation, and oxidative stress markers using S. cerevisiae as a system.
