Fibrosis is a consequence of aberrant wound healing processes that can be debilitating for patients and often are associated with highly morbid disease processes. Myofibroblasts play an important role in determining an appropriate physiologic response to tissue injury or an excessive response leading to fibrosis. Specifically, “supermature” focal adhesions, α-smooth muscle actin, and the myocardin-related transcription factor/serum response factor pathway likely play a significant role in the differentiation and survival of myofibroblasts in fibrotic lesions. Thus, targeting each of these and disrupting their functioning could lead to the development of therapeutic options for patients suffering from fibrosis and other sequelae of dysregulated wound healing. In this paper, we review the current literature concerning the roles of these three constituents of fibrotic signaling pathways, work already done in attempting to regulate these processes, and discuss the potential of these biomolecular constituents as therapeutic targets in future translational research.
