Abstract

Glioma represents the lethal neoplasm of the brain with dismal progression in its most aggressive form, that is, glioblastoma. Hypoxia is well appreciated to have a role in cellular migration and proliferation of a range of malignancies; however, its multifaceted impact on tumors of glial origin is not clear. The aim of present chapter is to present the integrated view of hypoxia involvement in the biology of gliomas. Hypoxia impacts the biology of glioma mainly through the transcriptional factors HIF1 alpha and exists in spatiotemporal heterogeneity in its expression in the tumor. The hypoxic microenvironment impacts the pathology of glioma on account of several mechanisms such as by altering the metabolic switch from oxidative to glycolytic metabolism, promoting the expression of tumor, promoting signaling in the form of VEGF, PI3k, and MAP kinase cascade. In addition, hypoxia is notorious to induce the refractiveness to the existing therapies such as radiation and temozolomide-mediated chemotherapy. Targeting hypoxia mediators in combination with the present therapeutic regime could potentially sensitize glioma cells to induce cell death and prevent the inevitable recurrence.
