1. Carnosine metabolism in diabetes is altered by reactive metabolites.

    Amino Acids 47(11):2367 (2015) PMID 26081982

    Carnosinase 1 (CN1) contributes to diabetic nephropathy by cleaving histidine-dipeptides which scavenge reactive oxygen and carbonyl species and increase nitric oxide (NO) production. In diabetic mice renal CN1 activity is increased, the regulatory mechanisms are unknown. We therefore analysed t...
