VEGFA and myocardial infarction: For VEGFA (vascular endothelial growth factor-α) and KDR (kinase insert domain receptor), compared with the sham group, the expressions of the MI control group and FD1000 group obviously increased (p < 0.05), indicating the expressions of the FD1000 group were higher than those of the MI group, suggesting that PN-F could induce VEGFA and KDR expressions.
