Carnitine Palmitoyltransferase 1 facilitates fatty acid oxidation in a noncell autonomous manner [CPT1a_RNAseq]
Ontology highlight
ABSTRACT: Mitochondrial fatty acid oxidation is facilitated by the combined activities of Carnitine Palmitoyltransferase 1 and Carnitine Palmitoyltransferase 2 which generate and utilize acylcarnitines respectively. We compared the response of mice with liver specific deficiencies in the liver enriched Cpt1a or the ubiquitous Cpt2 and discovered that they display unique metabolic, physiological and molecular phenotypes. The loss of Cpt1a or Cpt2 resulted in the induction of the muscle enriched isoenzyme, Cpt1b, in hepatocytes in a Ppara dependent manner. Primary component analysis also revealed overall differential grouping between mouse with deletions of either Cpt1a or Cpt2. Our results utilize stringent genetic mouse models to elucidate that the sequential steps to facilitate mitochondrial fatty acid oxidation may have other factors.
