Treatment with PARP inhibitor Olaparib causes cleft palate in mice. (A) Schematic representation of the in vivo dosing of Olaparib (50 mg/kg) and tissue harvesting schedule. (B) Phenotypic penetrance of cleft palate at E16.5 following i.p. injection of Olaparib (50 mg/kg) into pregnant C57BL/6 mice. (C) Gross morphology of cleft palate (asterisk, upper panels) and skeletal analysis (middle panels) in embryos harvested from C57BL/6 pregnant females injected with Olaparib. The lower panel shows the high-magnification images of the area highlighted in the yellow boxes in the middle panel. mx, maxilla; pmx, premaxilla; ppmx, palatal process of maxilla; ppp, palatal process of palatine.
