dc.description.abstractGlioblastoma multiforme (GBM) is one of the most aggressive and lethal brain cancers, known for its highly invasive nature and resistance to conventional therapies. Central to this resistance is the presence of glioblastoma stem cells (GSCs), which contribute to tumour recurrence and heterogeneity. This thesis investigates the roles of interferon-induced transmembrane proteins (IFITMs), specifically IFITM1 and IFITM3, within GSCs and their potential as therapeutic targets. The study provides a detailed analysis of IFITM1’s expression, subcellular localisation, and interaction with other proteins in response to interferon stimulation, employing advanced molecular techniques such as co-immunoprecipitation, immunofluorescence microscopy, and proteomic analysis. Key findings include the discovery that IFITM3 plays a critical role in regulating IFITM1’s expression and localisation, with significant implications for IFITM1’s function in cancer cell biology. This thesis also contributes to validating a novel interaction between IFITM1 and Lysosomal-associated membrane protein 1, suggesting a potential role for IFITM1 in autophagy, which could be pivotal in GBM’s resistance to treatment. These insights not only advance the understanding of IFITM proteins in GSCs but also highlight their potential as targets for therapeutic intervention in GBM. This work lays the foundation for future studies aimed at manipulating IFITM proteins to develop novel strategies for overcoming GBM treatment resistance.
