| abstractText | The metabolic factors causing cortical neuronal migration defects, hypotonia and malformation of cerebellum in patients and mice with severe peroxisome biogenesis disorders are still not identified. In the present investigation, we tested the hypothesis that the combined inactivity of peroxisomal beta-oxidation and ether lipid biosynthesis could be at the origin of these pathologies. Double MFP2/DAPAT knockout mice were generated and their postnatal phenotypes were compared with single knockouts and control mice. Cortical neuronal migration was not affected in DAPAT knockouts and only mildly in double MFP2/DAPAT knockout mice. The latter mice were severely hypotonic and usually died in the postnatal period. Both DAPAT and MFP2 single knockout mice exhibited delays in the formation of cerebellar folia. We conclude that the combined defect of peroxisomal beta-oxidation and ether lipid synthesis does not solely account for the typical cortical neuronal migration defect of mice with peroxisome biogenesis disorders but contributes to their hypotonia. |
