Table of Contents


Diabetes mellitus (DM) is due to a number of risk factors leading to hyperglycemia (HG), which can induce the generation of the reactive carbonyl species, methylglyoxal (MGO) via a down-regulation of the enzyme, glyoxylase-1 (Gly-1) that degrades MGO. MGO in turn can elicit deleterious effects to cellular calcium transporting proteins in the heart, resulting in cardiac dysfunction and diabetic cardiomyopathy (DC), and even sudden cardiac death (SCD) of the patient. Gene therapy to elevate the levels of Gly-1 to degrade MGO to physiological level can prevent the demise of the myocardium, resulting in normal function.

Keywords: Calcium heart, diabetes mellitus, diabetic cardiomyopathy, methylglyoxal
