Abstract
Glioblastoma multiforme (GBM) was recently shown to be dependent on extracellular sources of lipids to meet cellular requirements as opposed to de novo biosynthesis. We conducted LC-MS-based metabolomics to characterise the cell metabolome of GBM cell lines cultured under lipoprotein-deficient conditions to replicate nutrient stresses seen in vivo. As a result, cell line-specific metabolite changes were observed calling for the need for integration with transcriptomics data to elucidate genetic drivers of cell line-specific stress responses. This study has highlighted the metabolic dependencies of GBM under nutrient-limiting conditions which will inform on the development of new therapeutic strategies targeting stress responses.
