| Study Title | Hepatic bioenergetics and metabolism in mitochondrial disease: Insights from the Ndufs4 KO mouse model |
| Study Type | Multi-platform metabolomics analysis |
| Study Summary | Mitochondrial diseases, including Leigh syndrome, frequently result from complex I (CI) deficiencies and lack effective treatments. Investigating metabolic alterations in affected tissues is essential to understanding disease progression and identifying therapeutic targets. The aim of this project was to characterize the metabolic profile of Ndufs4 knockout (KO) mouse livers, a model of CI deficiency, using multi-platform metabolomics. Whole-liver extracts from Ndufs4 KO and wild-type mice were analyzed via untargeted GC-TOFMS and semi-targeted LC-MS/MS. Metabolic profiling revealed widespread disruptions, including altered glucose, amino acid, and nucleotide metabolism, as well as TCA cycle intermediates. Key findings included elevated levels of UDP-glucose and UDP-N-acetylglucosamine, indicating shifts toward anabolic pathways such as hexosamine biosynthesis and glycogen synthesis. These data highlight the potential role of metabolic reprogramming in liver adaptation to mitochondrial dysfunction and provide new directions for investigating interorgan metabolic dynamics in mitochondrial diseases. |
