Schematic representation of TGFβ pathway regulation by miR-331. In this model, miR-331 by targeting some genes (TGFβ-R1, TGFβ-1, SMAD2, and SMAD3) results in reduced TGFβ signaling pathway activity which in turn, effects the fibrotic genes expression of cardiac myofibroblasts and other related biological processes, including cell proliferation and migration.
