The chemokine receptor CXCR7 functions to regulate cardiac valve remodeling

Abstract excerpt

CXCR7 (RDC1), a G-protein-coupled receptor with conserved motifs characteristic of chemokine receptors, is enriched in endocardial and cushion mesenchymal cells in developing hearts, but its function is unclear. Cxcr7 germline deletion resulted in perinatal lethality with complete penetrance. Mutant embryos exhibited aortic and pulmonary valve stenosis due to semilunar valve thickening, with occasional...
