Tóm tắt

Mitochondrial long chain fatty acid β-oxidation is a critical central carbon catabolic process. The importance of fatty acid oxidation is made evident by the life-threatening disease associated with diverse inborn errors in the pathway. While inborn errors show multisystemic requirements for fatty acid oxidation, it is not clear from the clinical presentation of these enzyme deficiencies what the tissue specific roles of the pathway are compared to secondary systemic effects. To understand the cell or tissue specific contributions of fatty acid oxidation to systemic physiology, conditional knockouts in mice have been employed to determine the requirements of fatty acid oxidation in disparate cell types. This has produced a host of surprising results that sometimes run counter to the canonical view of this metabolic pathway. The rigor of conditional knockouts has also provided clarity over previous research utilizing cell lines in vitro or small molecule inhibitors with dubious specificity. Here we will summarize current research using mouse models of Carnitine Palmitoyltransferases to determine the tissue specific roles and requirements of long chain mitochondrial fatty acid β-oxidation.
