uNreveal the rOle of SpaRtin in MitochondriA

Project description

Uncovering the metabolic basis of a rare inherited neurological disorder

Troyer syndrome is a rare inherited neurological disorder characterised by progressive muscle weakness, developmental impairment and neurodegeneration. It is caused by mutations in the gene encoding the Spartin protein, but it remains poorly understood how these mutations disrupt cellular function and drive disease. Emerging evidence points to mitochondrial dysfunction as a central mechanism. With the support of the Marie Skłodowska-Curie Actions programme, the NORMA project aims to map the metabolic consequences of Spartin mutations across patient-derived fibroblasts and stem cell-derived motor neurons. Researchers will combine transcriptomics and metabolomics analysis to identify disrupted metabolic pathways. The goal is to develop targeted supplementation strategies to correct these dysfunctions and provide new insights into Troyer syndrome.

Objective

Troyer Syndrome (TS) is a rare and complex variant of Hereditary Spastic Paraplegia (HSP), driven by mutations in the SPG20 gene, which encodes the Spartin protein (SPART). This syndrome, characterized by neurodevelopmental impairments, remains poorly understood, particularly regarding the impact of SPART mutations on mitochondrial function. Although genomic technologies like Whole Exome and Whole Genome Sequencing have advanced our knowledge, the link between SPART mutations and metabolic dysfunctions in TS is still unclear. This project aims to fill this gap by integrating transcriptomics and metabolomics to study the effects of SPART mutations across three cellular models: fibroblasts derived from TS patients, motor neurons differentiated from patient-derived iPSCs, and CRISPR-Cas9-edited cells carrying specific SPART mutations. The hypothesis is that SPART mutations disrupt mitochondrial metabolic processes, which are central to TS pathogenesis. By employing these advanced -omics and functional approaches, we will map the metabolic alterations, aiming to correct these dysfunctions through targeted metabolite supplementation. This research not only offers a novel perspective on the molecular mechanisms underlying TS but also paves the way for potential therapeutic interventions. The project will significantly enhance my expertise in cutting-edge biomedical research while contributing valuable insights to the field of neurodegenerative diseases, potentially leading to improved diagnostics and therapies for TS and related disorders.
