The ontogeny of peroxisome-proliferator-activated receptor gene expression in the mouse and rat

Proc Biol Sci. 1992 Feb 22;247(1319):83-7. doi: 10.1098/rspb.1992.0012.


The expression of the gene coding for peroxisome-proliferator-activated receptor (PPAR), a novel transacting factor belonging to the steroid superfamily, has been determined in the mouse and rat throughout development using hybridization histochemistry. Messenger RNA is demonstrable in the liver and brown fat from the fetal period onwards and, additionally, in the heart, kidney and gut post-natally. It is proposed that the upregulation of transcription of peroxisomal beta oxidation genes in specific tissues follows binding of the receptor to its natural ligand. Thus PPAR may have an important role in cold adaptation and non-shivering thermogenesis as well as in detoxification.
