Methylglyoxal induces cardiac dysfunction through mechanisms involving altered intracellular calcium handling in the rat heart [PDF]
Chemico-Biological Interactions, 2024, 394, pp.110949Methylglyoxal (MGO) is an endogenous, highly reactive dicarbonyl metabolite generated under hyperglycaemic conditions. MGO plays a role in developing pathophysiological conditions, including diabetic cardiomyopathy. However, the mechanisms involved and the molecular targets of MGO in the heart have not been elucidated.
