Metabolic reprogramming in hereditary diseases

The Krebs cycle is implicated in nearly every aspect of mitochondrial homeostasis. Our research builds upon the ‘everything depends on everything’ view to investigate how the Krebs cycle functions in homeostasis and disease, with emphasis on mitochondrial disorders (MtD).

We apply experimental and computational approaches to investigate the critical interconnections between the Krebs cycle’s activity, the OxPhos system and mitochondrial biogenesis. Our goal is to identify disease-modifying target pathways and biomarkers linked to the metabolic manifestations of MtD.

  • Tools to explore the cell: Metabolic and isotopic labelling analyses, metabolic labelling of RNA, transcriptomics (RNA-seq, iCLIP-seq), molecular tools to visualize RNA, purification of protein-RNA complexes, metabolic flux analyses.
  • Disease modelling: genetically-engineered cell lines; cell models of hypoxia and pseudo-hypoxic states; metabolic reprogramming in cell culture.
