Figure 8. Working model of a novel mechanism for hyperglycemia-exacerbated myocardial ischemia/reperfusion injury.

Figure 8

Both diabetes-induced chronic hyperglycemia and acute hyperglycemia increased ALDH2 O-GlcNAc modification which decreased its activity, toxical aldehydes accumulation and cell apoptosis, thus contributing to the exacerbation of myocardial ischemia/reperfusion injury. Alda-1 reversed myocardial ischemia/reperfusion injury exacerbated by hyperglycemia through decreasing ALDH2 O-GlcNAc modification, as well as increasing its activity.
