DDX6 and Myocardial fibrosis: Curiously, miR-218-5p, a potential miRNA targeting DDX6, has been also reported to mediate myocardial fibrosis and inflammation after myocardial infarction [69,70,71,72], suggesting therefore that the so far unknown DDX6/miR-218-5p axis could play a regulatory role during fibrosis and inflammation in the infarcted heart.
