ABSTRACT
Hyperglycemia-related advanced glycation end product (AGE) formation is a key mechanism in diabetic nephropathy. Since methylglyoxal (MG) is a potent AGE precursor, we aimed to assess the role of MG-related AGE formation in the progression of renal damages. A comparative study between Wistar (W, normal) and Goto-Kakizaki (GK, nonobese type 2 diabetic) rats was performed at 6 and 14 months old and after 14 weeks of MG administration to 6-month-old rats. Diabetic rats showed progressive structural, biochemical, and functional alterations, including AGE, albuminuria, and tissue hypoxia, which were partially mimicked by MG administration to young GK rats. Aged Wistar rats had an impairment of some parameters, whereas MG administration caused a phenotype similar to young GK rats, including oxidative stress, impaired apoptotic and angiogenic markers, and structural lesions. MG accumulation specifically impaired several of the renal disease markers progressively observed in diabetic rats, and thus, it contributes to the progression of diabetic nephropathy
