UBE2S and myocardial infarction: The quantification analysis showed that although the ratio of AAR to left ventricular area (LVA) in siUbe2s group had no statistical significance when comparing with that of siCtrl, the ratio of IA to AAR was significantly higher in siUbe2s group (Figure 2C), suggesting that Ube2s expression knockdown increases myocardial infarct size after MI/R injury.
