Peroxisomes: A Nexus for Lipid Metabolism and Cellular Signaling

Open access
Lodhi, Irfan J., Semenkovich, Clay F.·2014·Cell Metabolism

Abstract

Peroxisomes are often dismissed as the cellular hoi polloi, relegated to cleaning up reactive oxygen chemical debris discarded by other organelles. However, their functions extend far beyond hydrogen peroxide metabolism. Peroxisomes are intimately associated with lipid droplets and mitochondria, and their ability to carry out fatty acid oxidation and lipid synthesis, especially the production of ether lipids, may be critical for generating cellular signals required for normal physiology. Here, we review the biology of peroxisomes and their potential relevance to human disorders including cancer, obesity-related diabetes, and degenerative neurologic disease.

  • PPARA is an important regulator of lipid metabolism and a ligand-activated transcription factor that increases expression of fatty acid oxidation genes and peroxisome abundance in the liver.

    “PPARA, a member of peroxisomes proliferator‐activated receptors (PPARs), is considered as an important regulator of lipid metabolism, and as a ligand‐activated transcription factor, it not only increases the expression of fatty acid oxidation genes, but also increases the abundance of peroxisomes in the liver.[ 21 ]”
  • Peroxisomes are single-membrane-bound organelles required for a subset of metabolic pathways, including ether lipid synthesis and very-long-chain fatty acid oxidation.

    “Peroxisomes are single-membrane-bound organelles required for a subset of metabolic pathways, including ether lipid synthesis and very-long-chain fatty acid oxidation (1).”
  • The peroxisome is the central site for processing fatty acid alcohols, producing diacylphospholipids or ether-linked phospholipids.

    “The peroxisome is the central site of fatty acid alcohol processing (52), which generates either diacylphospholipids or ether-linked phospholipids.”
  • The role of peroxisomal ABC transporters is not restricted to the catabolic function of peroxisomes but is associated with various metabolic functions including synthesis and degradation of lipids, cell signaling, inflammation control, and redox homeostasis.

    “The role of peroxisomal ABC transporters is therefore not restricted to the catabolic function of peroxisomes, but is fully associated with their various metabolic functions including synthesis and degradation of lipids, cell signaling, inflammation control, and redox homeostasis [ 11 , 12 , 13 , 14 , 15 ].”

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.
