title: [The role of fatty acids in gene regulation. An example of an important nutritional factor which may influence our genes].
abstract: Regulation of gene expression by specific nutrients has become a major field of nutrition research. Evidence is presented showing that dietary constituents specifically modulate gene transcription and transcript processing. The peroxisome proliferator-activated receptor (PPAR) is a member of the steroid hormone receptor superfamily and is activated by a variety of hypolipidemic drugs, termed peroxisome proliferators. Several genes have been shown to contain elements responsive to peroxisome proliferator-activated receptor. These include the genes that encode the peroxisomal enzymes involved in beta-oxidation of fatty acids. The retinoid receptor X is required, however, for PPAR to bind to its responsive element. The finding that fatty acids are PPAR activators suggests that fatty acids or their acyl CoA-derivatives may regulate the lipid metabolism via this receptor.
