Increased glyoxalase I levels inhibit accumulation of oxidative stress and an advanced glycation end product in mouse mesangial cells cultured in high glucose

Chronic high glucose levels lead to the formation of advanced glycation end-products (AGEs) as well as AGE precursors, such as methylglyoxal (MG) and glyoxal, via non-enzymatic glycation reactions in patients with diabetic mellitus. Glyoxalase 1 (GLO-1) detoxifies reactive dicarbonyls that form AGEs. To investigate the interaction between AGEs and GLO-1 in mesangial cells (MCs) under diabetic conditions, AGE levels and markers of oxidative...
