The expression of cytoglobin as a prognostic factor in gliomas: A retrospective analysis of 88 patients

Evidence suggests that cytoglobin (Cygb) may function as a tumor suppressor gene. Methods: We immunohistochemically evaluated the expression of Cygb, phosphatidylinositol-3 kinase (PI-3K), phosphorylated (p)-Akt, Interleukin-6 (IL-6), tumor necrosis factor-α (TNFα) and vascular endothelial growth factor (VEGF) in 88 patients with 41 high-grade gliomas and 47 low-grade gliomas.
