Abstract

Functional peroxisome deficiency, as encountered in Zellweger syndrome, causes a specific impairment of neuronal migration. Although the molecular mechanisms underlying the neuronal migration defect are at present unknown, the excess of very long chain fatty acids in brain, a consequence of peroxisomalbeta-oxidation deficiency, has often been hypothesized to play a major role. The purpose of the present study was to investigate the contribution of peroxisomal dysfunction in brain as opposed to peroxisomal dysfunction in extraneuronal tissues to the migration defect. Peroxisomes were selectively reconstituted either in brain or liver of Pex5 knock-out mice, a model for Zellweger syndrome, by tissue-selective overexpression of Pex5p. We found that both rescue strains exhibited a significant correction of the neuronal migration defect despite an incomplete reconstitution of peroxisomal function in the targeted tissue. Animals with a simultaneous rescue of peroxisomes in both tissues displayed a pattern of neuronal migration indistinguishable from that of wild-type animals on the basis of cresyl violet staining and 5',3'-bromo-2'-deoxyuridine birth-dating analysis. These data suggest that peroxisomal metabolism in brain but also in extraneuronal tissues affects the normal development of the mouse neocortex. In liver-rescued mice, the improvement of the neuronal migration was not accompanied by changes in very long chain fatty acid, docosahexaenoic acid, or plasmalogen levels in brain, indicating that other metabolic factors can influence the neuronal migration process.

  • In Pex5-deficient mice (ubiquitous KO), liver-specific ectopic expression of Pex5 results in partial rescue of brain defects.

    “This finding is further corroborated by observations in Pex5-deficient mice (ubiquitous KO), in which liver-specific ectopic expression of Pex5 [77] resulted in partial rescue of the brain defects.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
