Circular RNA hsa_circ_105039 Promotes Cardiomyocyte Differentiation by Sponging miR-17 to Regulate cyclinD2 Expression

hsa_circ_105039 was underexpressed in the heart tissue of patients with congenital heart disease. Investigators found that hsa_circ_105039 overexpression promoted cell differentiation, viability and migration; whereas apoptosis was simultaneously repressed.
