H19 and cardiovascular disorder: The competing endogenous RNA (ceRNA) theory has shed new light on how H19 participates in the pathological process of AMI.32 There is wide consensus that lncRNAs may exert their biological effects by acting as endogenous decoys to sponge miRNAs, which consequently segregates miRNAs from their target mRNAs.20, 25 In recent decades, the vital function of miRNAs in cardiovascular disease has been well characterized.
