To further explore the role of the Notch pathway in cardioprotection conferred by Nogo-B in vivo, AAV-Nogo-B and AAV-NC were injected in Notch1-EC+/− and WT mice hearts 4 weeks before MI and the survival rate (Fig. 8B), cardiac function (Fig. 8C), scar size (Fig. 8D), apoptosis of cardiomyocytes (Fig. 8E), and angiogenesis (Fig. 8F) were assessed after MI. This evidence concerns the gene NOTCH1 and myocardial infarction.
