RYR2 and atrial fibrillation: In non-neoplastic diseases, HCM cells and H9C2 cells that had been transfected with pcDNA-LINC00472 or si-miR-24 exhibited suppressed miR-24 levels and elevated JP2 mRNA/protein and RyR2 protein levels, implying the presence of negative relationships among miR-24, JP2, LINC00472 and RyR2 in regulation of AF (Wang et al., 2019b).
