1 Couldwell, William T.; Gillespie, David L.; Jensen, Randy L.Identification of hypoxia-induced genes in a malignant glioma cell line (U-251) by cDNA microarray analysisOvercoming the metabolic restrictions of hypoxia may allow the progression of lower-grade tumors to glioblastoma multiforme. Our findings of up-regulation of HIF-1α and its downstream targets VEGF, GLUT-1, and CAIX in higher-grade gliomas support this hypothesis. We compared the gene expression pro...Glioblastoma multiforme; U-251; Hypoxia; Microarray analysis; Brain tumor; Depp; Astrocytoma2007
