Misregulation of SDF1-CXCR4 signaling impairs early cardiac neural crest cell migration leading to conotruncal defects.
RATIONALE Cardiac neural crest cells (NCs) contribute to heart morphogenesis by giving rise to a variety of cell types from mesenchyme of the outflow tract, ventricular septum, and semilunar valves to neurons of the cardiac ganglia and smooth muscles of the great arteries. Failure in cardiac NC development results in outflow and ventricular septation defects commonly observed in congenital hear...
متن کاملExploring the developmental mechanisms underlying Wolf-Hirschhorn Syndrome: Evidence for defects in neural crest cell migration
Wolf-Hirschhorn Syndrome (WHS) is a neurodevelopmental disorder characterized by mental retardation, craniofacial malformation, and defects in skeletal and heart development. The syndrome is associated with irregularities on the short arm of chromosome 4, including deletions of varying sizes and microduplications. Many of these genotypic aberrations in humans have been correlated with the class...
متن کاملThe heart in selected congenital malformations. A lesson in pathogenetic relationships.
The application of new knowledge on the pathogenesis of congenital heart defects has increased our understanding of associated, non-cardiac malformations seen in certain syndromes. Defects in the proliferation and migration of neural crest cells are thought to contribute to conotruncal defects. These are seen in association with conditions such as DiGeorge syndrome. CHARGE association, hemifaci...
متن کاملA neural crest origin for cohesinopathy heart defects.
Mutations in subunits or regulators of cohesin cause a spectrum of disorders in humans known as the 'cohesinopathies'. Cohesinopathies, including the best known example Cornelia de Lange syndrome (CdLS), are characterized by broad spectrum, multifactorial developmental anomalies. Heart defects occur at high frequency and can reach up to 30% in CdLS. The mechanisms by which heart defects occur a...
متن کاملRisk factors for conotruncal cardiac defects in Atlanta.
Because the causes of conotruncal cardiac defects are poorly understood, a case-control study was conducted to investigate maternal risk factors for conotruncal cardiac defects. Eligible cases included all infants who were born from 1976 through 1980 to residents of the five county metropolitan Atlanta area and diagnosed with truncus arteriosus, transposition of the great arteries or tetralogy ...
