In addition, PTP1b, Ephrin‐A3 (EFNA3) and Dapk1 were also the target genes of miR‐210, and miR‐210 overexpression inhibited the apoptosis of myocardial cells after myocardial infarction by down‐regulating protein levels of PTP1b,Dapk142 and EFNA3.10 APC is an anti‐proliferating gene and a direct target of miR‐210. This evidence concerns the gene PTPN1 and myocardial infarction.
