Then, the concepts that activate specifically by RA treatment were Myogenesis (Troponin C1, Integrins A7/B1/B5, Myosin Light Chain Kinase, among others), Integrins / Cell Adhesion, and Cardiomyopathy related genes (Integrins A1/A3/A8/A7, B1/B5, TGFB2, Troponin C1), and elastic fibers formation (Fibulin 1, Latent transforming growth factor beta binding protein 1/3, Lysyl Oxidase Like 2, and Integrins). The gene discussed is TGFB2; the disease is cardiomyopathy.
