That study also demonstrated that miR-486 expression can be activated by myocardin-related transcription factor A (MRTF-A, also referred to as MAL/MKL1) [20], a coregulator of the serum response transcription factor, which has been shown to regulate actin polymerization and Rho signaling in cardiac hypertrophy [40,41]. Here, MRTFA is linked to cardiac hypertrophy.
