Heart damage in diabetics may be closely related to the possible synergistic cellular damage from hyperglycemia and increased methylglyoxal levels. This study investigated the effects of glucose and/or methylglyoxal and/or metformin on H9c2 reactive oxygen species (ROS) generation measured by a dichlorofluorescein diacetate (DCFDA) assay and cell viability measured by a cell counting kit-8 assay after various treatments for 24 hours.
Glucose treatment (5 mM-40 mM) displayed similar cell viability (n=4) and ROS generation (n=7) when compared to control cells. By contrast, methylglyoxal (5 µM-1400 µM) decreased cell viability at higher concentration (1000 µM (51 ± 8%); 1200 µM (41 …
