EDNRA and myocardial infarction: qRT-PCR results showed that, compared to the sham group, the mRNA expression levels of the 10 genes in the myocardial infarction tissue of rats 28 days post-MI were elevated; five of these genes, including COL1A2, EDNRA, PCOLCE2, CRISPLD2, and FKBP5, exhibited significant increases (Figure 6F).
