Research Theme

The main focus of our research is the plasticity and development of human brain tumors
We are interested in understanding how interactions between cell intrinsic and extrinsic signaling pathways control the stem and tumor-initiating properties of glioma stem cells.

Our project aims at characterizing intra- and extracellular molecular pathways that restrict the stem-like potential, and consequently the tumorigenicity of human glioma stem cells (GSC), as compared to human neural stem cells (NSC). It takes advantage of the unique model offered by the couple formed by GSC and their non-tumorigenic counterparts miR-302-367-GSC. Recent advances show that the metabolic changes could be at the core of tumorigenesis. They have noteworthy led to the identification of mutations in metabolic enzymes that drive cancer pathogenesis, of metabolic markers of cancer progression, and to the recognition that metabolic changes may affect the cell phenotype. In light of these discoveries, we postulate that a change in cell phenotype as radical as that induced by miR-302-367 should result in metabolic alterations instrumental in the loss of tumorigenic and stem-like properties

We will specifically:
1. Determine the mechanism and functional consequences of the metabolite rearrangements accompanying the irreversible
repression of GSC stem and tumor-initiating properties.
2. Extend the identification of compounds targeting GSC and and transfer
