The induction of omega and beta-oxidation of fatty acids and effect on alpha 2u globulin content in the liver and kidney of rats administered 2,2,4-trimethylpentane. 1987

E A Lock, and M D Stonard, and C R Elcombe

The effect of daily administration of 12 mmol/kg 2,2,4-trimethylpentane for 10 d on hepatic and renal microsomal mono-oxygenase activity, peroxisomal beta-oxidation and the concentration of alpha 2u-globulin has been examined in male and female rats. 2,2,4-Trimethylpentane produces liver and, to a lesser extent, kidney enlargement. This is associated with the selective induction of cytochrome P-450-mediated omega-oxidation and peroxisomal beta-oxidation of fatty acids and proliferation of peroxisomes. Male rats show a more marked response than female rats. 2,2,4-Trimethylpentane produces an increase in alpha 2u-globulin in the kidney of male rats. The relevance of selective induction of omega- and beta-oxidation of fatty acids and accumulation of alpha 2u-globulin to renal tubular necrosis in male rats requires further study.

UI MeSH Term Description Entries
D007668 Kidney Body organ that filters blood for the secretion of URINE and that regulates ion concentrations. Kidneys
D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008297 Male Males
D008830 Microbodies Electron-dense cytoplasmic particles bounded by a single membrane, such as PEROXISOMES; GLYOXYSOMES; and glycosomes. Glycosomes,Glycosome,Microbody
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D008862 Microsomes, Liver Closed vesicles of fragmented endoplasmic reticulum created when liver cells or tissue are disrupted by homogenization. They may be smooth or rough. Liver Microsomes,Liver Microsome,Microsome, Liver
D009795 Octanes Eight-carbon saturated hydrocarbon group of the methane series. Include isomers and derivatives. Isooctanes
D005227 Fatty Acids Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED).

D000510 Alpha-Globulins Serum proteins that have the most rapid migration during ELECTROPHORESIS. This subgroup of globulins is divided into faster and slower alpha(1)- and alpha(2)-globulins. Alpha-Globulin,Alpha Globulin,Alpha Globulins
