Smooth muscle cell phenotype is associated with changes in miRNA expression profile.

  • Actin/MRTF-A regulate a set of miRNAs (miR-1, miR-22, miR-143, miR-145 and miR-378a) in mouse and human smooth muscle.

  • Actin/MRTF-A-regulated miRNAs are enriched in muscle tissue and associated with the contractile phenotype of smooth muscle cells.

  • Mild aortic dilations are associated with depolymerization of actin and reduced expression of actin/MRTF-A-regulated miRNAs.
