Microsomal and cytosolic epoxide hydrolases, the peroxisomal fatty acid beta-oxidation system and catalase. Activities, distribution and induction in…
1988
A number of structurally unrelated hypolipidaemic agents and certain phthalate-ester plasticizers induce hepatomegaly and proliferation of peroxisomes in rodent liver, but there is relatively limited data regarding the specific effects of these drugs on liver non-parenchymal cells. In the present study, liver parenchymal, Kupffer and endothelial cells from untreated and fenofibrate-fed rats were isolated and the activities of two enzymes associated with peroxisomes (catalase and the peroxisomal fatty acid beta-oxidation system) as well as cytosolic and microsomal epoxide hydrolase were measured. Microsomal epoxide hydrolase, cytosolic epoxide hydrolase and catalase activities were 7-12-fold…
Hepatic steatosis and peroxisomal fatty acid beta-oxidation.
2012
Three subhepatocellular compartments concur for fatty acids degradation including ω-oxidation in endoplasmic reticulum and β-oxidation in both mitochondria and peroxisomes. Deficits affecting the peroxisomal physiology may be associated with multiple metabolic disturbances. Nowadays, a growing body of evidence underlines the key role of peroxisomal β-oxidation in the sensing of lipid metabolism through the production/degradation of some essential metabolites. Lessons from several mice models strengthen the link between fatty acid β-oxidation in peroxisomes and the nuclear hormone receptor Peroxisome Proliferator-Activated Receptor (PPAR)-α with an additional level of coregualtor complexity,…
