Glioblastoma multiforme (GBM) is a highly invasive, highly vascularized, and heterogeneous malignant tumor of the brain. Due to the highly infiltrative phenotype of GBM, surgery often leaves behind residual tumor cells. In many cases, recurrence occurs close to the surgical margin suggesting the role of these remaining cells in promoting tumor aggressiveness. Rapidly growing tumor creates subsequent hypoxic, and hypovascular core due to limited nutrients, whereas tumor cells in the leading edge have access to nutrients from vasculature enriched microenvironment. Studies have identified the cellular and molecular heterogeneity between the tumors in core and edge. Still, their mechanisms of intercellular …

Glioblastoma (GBM) is the most common adult primary malignant brain tumor with a median survival of about 15 months, even after aggressive treatment. Treatment of GBM is difficult for multiple reasons including the location of the tumor, tumor invasiveness, and the high degree of both inter-and intra-tumoral heterogeneity. Contributing to intratumoral heterogeneity are highly tumorigenic, stem-like tumor cells, with the capacity to self-renew and propagate the tumor, termed brain tumor initiating cells (BTICs). BTICs are also commonly therapy resistant, highly invasive, and metabolically plastic with elevated expression of glucose transporter 3 (GLUT3) allowing them to preferentially survive in low nutrient …

ABSTRACT Glioblastoma (GBM) is the most common and devastating primary CNS brain tumor with a median survival time of around 14 months. Most patients succumb to re-current disease which is often more malignant than the primary tumor and is frequently therapy resistant. There have not been significant advances in the treatment of GBM despite decades of research. This is partly due to the lack of accurate preclinical models and of the focus on primary rather than recurrent tumors. We created a 350 gene custom GBM-specific panel which contains 16 molecular signatures including molecular sub-typing signatures. We have demonstrated concordance of …
