The Glioblastoma Multiforme is a highly aggressive tumor, with a high recurrence and death rates. Studies have shown that the GBM is sustained by a subpopulation of cells with stem cells- like characteristics, denominated Glioblastoma Stem Cells. Those cells are resistant to chemo and radiotherapy, and are responsible for the low success rate of treatments in this tumor. Our group has described the role of the Protein Prion Celular (PrPC) in the biology of the GSC, being involved in the modulation of proliferation and self-renewal of those cells. The PrPC is a GPI- anchored protein, capable of acting as a scaffold protein, forming complexes with multiple proteins, such as stemness markers. Our group has described a heterogeneous gene (PRNP) and protein expression of PrPC in glioblastoma samples being its high expression correlated with increased tumor proliferation and decreased patient survival. Thus, the main goal of this project is to evaluate the differentially expressed genes in GSCs expressing distinct PrPC levels to identify novel potential targets of PrPC.
