Liver mRNA expression in 25 mice with or without genetic defects of mitochondrial fatty acid oxidation (Acadl and Acadvl knockout) using RNA sequencing


ABSTRACT: full title: A mitochondrial long-chain fatty acid oxidation defect in a mouse model leads to dysregulation of plasma long-chain acylcarnitines, dysregulation of plasma amino acids, and an increased reliance on glucocorticoid signaling to maintain euglycemia during fasting. [liver] The liver is a major source of energy substrates during metabolic stress: fasting, prolonged exercise, febrile illness. Fasting-induced hypoglycemia is a characteristic feature of FAO disorders including very long chain acyl-CoA dehydrogenase (VLCAD) deficiency (VLCADD). However, the pathophysiological mechanisms that underlie the diversity of clinical presentation of FAO dysfunction are not known. Here, we investigated the transcriptional response in liver tissue to the FAO defect in a model of VLCADD: the long-chain acyl-CoA dehydrogenase (LCAD) knockout (KO) mouse. We found that differentially expressed genes from the liver were associated with molecular networks annotated for fatty acid oxidation and cholesterol biosynthesis from population-based networks.
