| abstractText | Patients with an acyl-CoA dehydrogenase deficiency share the disease features of hypoglycemia, hyperammonemia, tissue fatty change, hypoketonemia, carnitine deficiency, and organic acidemia due to apparent disruption of normal fatty acid, glucose, and urea metabolism. Most of the acute clinical episodes occur in young children. These episodes are precipitated by fasting and are often fatal, with the in vivo mechanisms essentially unknown. Since the genes of the rate controlling enzymes of these pathways are tissue and developmentally regulated at the transcriptional level, we measured, throughout neonatal development, the steady-state mRNA levels of long-chain, medium-chain, and short-chain (SCAD) acyl-CoA dehydrogenases, pyruvate carboxylase (PC), phosphoenolpyruvate carboxykinase (PEPCK), carbamyl phosphate synthetase I (CPS), ornithine transcarbamylase (OTC), and argininosuccinate synthetase (AS) in fed or fasted SCAD-deficient BALB/ByJ mice compared to BALB/cBy controls. Overall, our results showed no major effects on expression of acyl-CoA dehydrogenases due to SCAD deficiency, regardless of age or fasting. In SCAD-deficient mice we found depressed mRNA expression and enzyme activity for the urea cycle enzymes CPS and AS at 6 days of age, and found no apparent effects on expression of gluconeogenic enzymes PC or PEPCK. There was a period of overall lower gene expression for most genes at 6 and 15 days, which appears to be in parallel with the developmental period when children with these diseases are most severely affected. |
