Metabolic reprogramming from fatty acid oxidation to glycolysis in a patient mutation knock-in mouse model of Barth Syndrome.[mouse]

Project description:Mitochondria are central for cellular metabolism and energy supply. Barth Syndrome (BTHS) is a severe disorder due to dysfunction of the mitochondrial cardiolipin acyl transferase tafazzin. Altered cardiolipin remodeling affects mitochondrial inner membrane organization and function of membrane proteins such as transporters and the oxidative phosphorylation (OXPHOS) system. Here, we describe a mouse model that carries a G197V exchange in tafazzin, corresponding to BTHS patient. TAZG197V mice recapitulate disease-specific pathology including cardiac dysfunction and reduced oxidative phosphorylation. We show that mutant mitochondria display defective fatty acid driven oxidative phosphorylation due to reduced levels of carnitine palmitoyl transferases. A metabolic switch in ATP production from OXPHOS to glycolysis is apparent in mouse heart and patient iPS cell-derived cardiomyocytes. An increase in glycolytic ATP production inactivates AMPK causing altered metabolic signaling in TAZG197V. Treatment of mutant cells with AMPK activator reestablishes fatty acid driven OXPHOS and protects mice against cardiac failure.

Nuclear Receptor Co-repressor NCoR1 governs immune-tolerance in conventional dendritic cells by fine-tuning glycolysis and fatty acid oxidation

Project description:In this study, we focused on demonstrating the metabolic aspect of NCoR1 in the regulation of dendritic cells (DCs) functionality. We report that NCoR1 deficient tolerogenic DCs meet their anabolic requirements through enhanced glycolysis and OxPhos, supported by FAO-driven oxygen consumption. Furthermore, individual and dual inhibition of glycolysis through HIF-1α inhibitor (KC7F2) and fatty acid oxidation through CPT1 inhibitor (etomoxir) significantly impaired the secretion of tolerogenic cytokines. To validate the same at the global mRNA level we did bulk RNA-seq to determine the differentially expressed genes in control and NCoR1 KD 6h CpG activated DCs with and without inhibitor treatment.

Genome-wide analysis of gene transcription in myocardium of the doxycycline inducible Tafazzin shRNA knockdown mouse model of Barth syndrome

Project description:Analysis of the transcriptome of cardiac tissue from mice trangenically engineered with a doxycycline inducible Tafazzin shRNA knockdown to mimic the loss of function of Tafazzin in Barth syndrome. ShRNA induced knockdown mice were compared to wildtype littermates also fed the doxycyline diet. The hypothesis was to investigate adaptive metabolic and compensatory gene transcriptional changes in myocardium of the mouse model of Barth syndrome Total RNA obtained from 2 month old cardiac tissue from the doxycycline inducible shRNA Tafazzin knockdown mouse model of Barth syndrome compared to wildtype littermates also fed 625 mg/Kg doxycycline diet
