| Popis: | Administration of the cleft palate teratogen chlorcyclizine or norchlorcyclizine to pregnant rats causes an alteration in glycosaminoglycans (GAGs) in embryonic palatal shelves. Pulse-chase experiments in vitro indicate that norchlorcyclizine enhances the degradation of hyaluronic acid and chondroitin sulfate but has little or no effect on their synthesis. These changes in GAGs are caused by concentrations of norchlorcyclizine that have no appreciable effect on DNA or protein synthesis. These findings suggest that degradation of palatal GAGs may be the primary biochemical defect responsible for the inhibition of palatal shelf elevation by norchlorcyclizine. |
