Regulation of gene expression by fatty acids: Special reference to fatty acid-binding protein (FABP)

摘要

During the last years, the direct involvement of lipidic nutrients in the regulation of genes has been established. Fatty acids may induce or repress the transcription rate of several genes involved in both lipid and carbohydrate metabolisms. Gene up-regulation has been found in various tissues including liver, adipose tissue and small intestine. It is only triggered by saturated and unsaturated long-chain fatty acids or their CoA-derivatives. In contrast, gene down-regulation appears to be restricted to the liver.
