AKT1 and atrial fibrillation: Chen et al. constructed an AF-related ceRNA network by identifying lncRNAs from the GSE41177 and GSE79768 datasets, and they reported that lncRNA FAM201A acts as a miRNA sponge of miR-33a-3p to upregulate the expression of the Rac family small GTPase 3 (RAC3) target gene, thereby participating in the regulation of AF susceptibility (24).
