| Study Title | Metabolomics analysis of plasma from CHCHD10S59L/+ KI mice |
| Study Summary | Mutations in the coiled-coil-helix-coiled-coil-helix domain containing 10 (CHCHD10) gene have been associated with a large clinical spectrum including myopathy, cardiomyopathy and amyotrophic lateral sclerosis (ALS). Herein, we analyzed the metabolic changes induced by the p.S59L CHCHD10 mutation to identify new therapeutic opportunities. Using metabolomic, lipidomic and proteomic analysis we observed a strong alteration of metabolism in plasma and heart of Chchd10S59L/+ mice compared to their wild type littermates at pre-symptomatic and symptomatic stages. In plasma, levels of phospholipids were decreased while those of carnitine derivatives and most of amino acids were increased. The cardiac tissue from Chchd10S59L/+ mice showed a decreased Oxidative Phosphorylation (OXPHOS) and β-oxidation proteins levels as well as tricarboxylic acid cycle (TCA) intermediates and carnitine pathway metabolism. In parallel, lipidomics analysis reveals a drastic change in the lipidome, including triglyceride, cardiolipin and phospholipids. Consistent with this energetic deficiency in cardiac tissue, we show that L-acetylcarnitine supplementation improves the mitochondrial network length in IPS-derived cardiomyocytes from a patient carrying the CHCHD10S59L/+ mutation. These data indicate that a bioenergetic intermediate such as L-acetylcarnitine may restore mitochondrial function in CHCHD10-related disease, due to the reduction in energy deficit that could be compensated by carnitine metabolic pathways. |
