A CUEDC2 ablation reduced I/R injury, which was induced by 30 minutes of ischemia followed by 24 hours reperfusion. AAR, area at risk; LV, left ventricular area, IRI, area of I/R injury. The ratios of AAR to LV, IRI to AAR and IRI to LV are shown. * p < 0.0001 compared with WT, n = 15 mice per group. (top panel) Representative cross-sectional slices derived from the hearts stained by TTC. Area of I/R injury is indicated in light pink.
