DiGeorge critical region 8 (Dgcr8), a gene that maps to the common deletion region of DGS, encodes a double stranded RNA-binding protein that is essential for miRNA biogenesis. To address the potential contribution of Dgcr8 insufficiency to cardiovascular development, we have inactivated Dgcr8 in cardiac neural crest cells (cNCCs). Dgcr8 mutants displayed a wide spectrum of malformations, including persistent truncus arteriosus (PTA) and ventricular septal defect (VSD). Interestingly, Dgcr8-null cNCCs that properly migrated into the cardiac outflow tract (OFT), proliferate normally and differentiate into vascular smooth muscle cells. However, loss of Dgcr8 causes a significant portion of the cNCCs to undergo apoptosis, causing a decrease in the pool of progenitors required for OFT remodeling. Our data uncover a new role of Dgcr8 in cardiovascular morphogenesis, plausibly as part of transmission mechanism for FGF-dependent survival cue for migrating cNCCs."xsd:string |
