Results also go in hand with the ontology bioinformatics evidence that (FENDRR lncRNA, miRNA-197-5p, and miRNA-221-3p) networks synergistically regulate the ABHD4 mRNA expression in ACS, and thus shed light on a novel molecular mechanism in myocardial ischemia (Figure 4A,B and Figure 5). Here, ABHD4 is linked to myocardial ischemia.
