Regulation of liver carnitine palmitoyltransferase I gene expression by hormones and fatty acids

This brief review focuses on the transcriptional regulation of liver carnitine palmitoyltransferase I (L-CPT I) by pancreatic and thyroid hormones and by long-chain fatty acids (LCFA). Both glucagon and 3,3',5-tri-iodothyronine (T(3)) enhanced the transcription of the gene encoding L-CPT I, whereas insulin had the opposite effect. Interestingly, the transcriptional effect of T(3) required, in addition to the thyroid-responsive element, the...
