Beta-oxidation of carboxylates takes place both in mitochondria and peroxisomes and in each pathway parallel enzymes exist for each conversion step. In order to better define the substrate specificities of these enzymes and in particular the elusive role of peroxisomal MFP-1, hepatocyte cultures from mice with peroxisomal gene knockouts were used to assess the consequences on substrate degradation. Hepatocytes from mice with liver selective elimination of peroxisomes displayed severely impaired oxidation of 2-methylhexadecanoic acid, the bile acid intermediate trihydroxycholestanoic acid (THCA), and tetradecanedioic acid. In contrast, mitochondrial beta-oxidation rates of palmitate were doubled, despite the severely affected inner mitochondrial membrane. As expected, beta-oxidation of the branched chain compounds 2-methylhexadecanoic acid and THCA was reduced in hepatocytes from mice with inactivation of MFP-2. More surprisingly, dicarboxylic fatty acid oxidation was impaired in MFP-1 but not in MFP-2 knockout hepatocytes, indicating that MFP-1 might play more than an obsolete role in peroxisomal beta-oxidation. << Less

The peroxisomal enzyme L-PBE is required to prevent the dietary toxicity of medium-chain fatty acids.
Ding J., Loizides-Mangold U., Rando G., Zoete V., Michielin O., Reddy J.K., Wahli W., Riezman H., Thorens B.

Specific metabolic pathways are activated by different nutrients to adapt the organism to available resources. Although essential, these mechanisms are incompletely defined. Here, we report that medium-chain fatty acids contained in coconut oil, a major source of dietary fat, induce the liver ω-oxidation genes Cyp4a10 and Cyp4a14 to increase the production of dicarboxylic fatty acids. Furthermore, these activate all ω- and β-oxidation pathways through peroxisome proliferator activated receptor (PPAR) α and PPARγ, an activation loop normally kept under control by dicarboxylic fatty acid degradation by the peroxisomal enzyme L-PBE. Indeed, L-pbe(-/-) mice fed coconut oil overaccumulate dicarboxylic fatty acids, which activate all fatty acid oxidation pathways and lead to liver inflammation, fibrosis, and death. Thus, the correct homeostasis of dicarboxylic fatty acids is a means to regulate the efficient utilization of ingested medium-chain fatty acids, and its deregulation exemplifies the intricate relationship between impaired metabolism and inflammation. << Less
