NFE2L2 and familial dilated cardiomyopathy: This review highlights the role of miRNAs, which can act as the nodes of signalling networks that regulate the progression of DCM and also tries to decipher the complicated cross-talk between miRNAs and DCM-related signalling pathways through various protein factors modulation, which includes RyR-2, TGF-β, IGF-1R, NF-κB and Nrf-2 and also immunological regulation of cardiomyocytes.
