Abstract

The ontogeny of the following peroxisomal metabolic pathways was evaluated in mouse liver and brain: α-oxidation, β-oxidation and ether phospholipid synthesis. In mouse embryos lacking functional peroxisomes (PEX5-/- knock-out), a deficiency of plasmalogens and an accumulation of the very-long-chain fatty acid C26:0 was observed in comparison with control littermates, indicating that ether phospholipid synthesis and β-oxidation are already active at mid-gestation in the mouse. Northern analysis revealed that the enzymes required for the β-oxidation of straight-chain substrates are present in liver and brain during embryonic development but that those responsible for the degradation of branched-chain substrates are present only in liver from late gestation onwards. The expression pattern of transcripts encoding enzymes of the α-oxidation pathway suggested that α-oxidation is initiated in the liver around birth and is not active in brain throughout development. Remarkably, a strong induction of the mRNA levels of enzymes involved in α-oxidation and β-oxidation was observed around birth in the liver. In contrast, enzyme transcripts that were expressed in brain were present at rather constant levels throughout prenatal and postnatal development. These results suggest that the defective ether phospholipid synthesis and/or peroxisomal β-oxidation of straight-chain fatty acids might be involved in the pathogenesis of the prenatal organ defects in peroxisome-deficient mice and men.

  • In the murine brain, mRNA levels of peroxisomal β-oxidation enzymes (ACOX1, DBP, ACAA1a), ABC transporters ABCD2 and ABCD3, and ether phospholipid biosynthesis enzymes increased after birth, reached a maximum during the first weeks and then declined.

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.
