We utilized TargetScan, miRanda and miRDB to identify the potential binding sites for miR-210-3p and investigate the molecular mechanism underlying the effects of miR-210-3p on AF; among them, glycerol-3-phosphate dehydrogenase 1-like (GPD1L) was strongly silenced and was a very interesting candidate (Fig. 5A). The gene discussed is GPD1L; the disease is atrial fibrillation.
