The mortality of patients with malignant gliomas remains high despite the advancement in multi-modal therapy including surgery, radio- and chemotherapy. Glioma stem cells (GSCs), sharing some characteristics with normal neural stem cells (NSCs), contribute to the cellular origin for primary gliomas
Up-regulation of vascular endothelial growth factor expression in a rat glioma is conferred by two distinct hypoxia-driven mechanisms.

Up-regulation of vascular endothelial growth factor (VEGF) expression is a major event leading to neovascularization in malignant gliomas. Hypoxia is believed to be the crucial environmental stimulus for this up-regulation. To critically assess this hypothesis, we asked whether the mechanisms

Treatment of malignant glioma is a challenge facing cancer therapy. In addition to surgery, and chemotherapy, radiotherapy (RT) is one of the most effective modalities of glioma treatment. However, there are two crucial challenges for RT facing malignant glioma therapy: first, gliomas are known to
Loss of cell-matrix contact increases hypoxia-inducible factor-dependent transcriptional activity in glioma cells.

In a variety of malignomas, the acquisition of a mesenchymal phenotype has been linked with anchorage-independent growth and invasiveness. To some extent, glioma cells are able to survive a loss of cell-matrix contact. We here describe that non-adherent culture of glioma cells was accompanied by an
CD133 glycosylation is enhanced by hypoxia in cultured glioma stem cells.

The cancer stem cell (CSC) marker CD133 is widely expressed in gliomas and employed mostly by use of the CD133/1 antibody which binds the extracellular glycosylated AC133 epitope. CD133 recognition may, however, be affected by its glycosylation pattern and oxygen tension. The present study
HIF1α regulates single differentiated glioma cell dedifferentiation to stem-like cell phenotypes with high tumorigenic potential under hypoxia.

The standard treatment for Glioblastoma multiforme (GBM) is surgical resection and subsequent radiotherapy and chemotherapy. Surgical resection of GBM is typically restricted because of its invasive growth, which results in residual tumor cells including glioma stem cells (GSCs) and differentiated
Effect of hypoxia-inducible factor-1alpha silencing on the sensitivity of human brain glioma cells to doxorubicin and etoposide.

Multidrug resistance (MDR) is a significant problem underlying the poor prognosis associated with gliomas. Hypoxia-inducible factor-1alpha (HIF-1alpha) is thought to induce the genes expression involved in MDR. To evaluate the effect of silencing HIF-1alpha in human glioma T98G cells, cells were
IDH1(R132H) mutation increases U87 glioma cell sensitivity to radiation therapy in hypoxia.

Prijava Registriraj se
OBJECTIVE
IDH1 codon 132 mutation (mostly Arg132His) is frequently found in gliomas and is associated with longer survival. However, it is still unclear whether IDH1 mutation renders the cell more vulnerable to current treatment, radio- and chemotherapy.
METHODS
We transduced U87 with wild type IDH1
CXCR7 is induced by hypoxia and mediates glioma cell migration towards SDF-1α.

BACKGROUND
Glioblastomas, the most common and malignant brain tumors of the central nervous system, exhibit high invasive capacity, which hinders effective therapy. Therefore, intense efforts aimed at improved therapeutics are ongoing to delineate the molecular mechanisms governing glioma cell

Hypoxia commonly occurs in solid tumors of the central nervous system (CNS) and often interferes with therapies designed to stop their growth. We found that pediatric high-grade glioma (HGG)-derived precursors showed greater expansion under lower oxygen tension, typical of solid tumors, than normal

One of the most sensitive hypoxia detection methods is based on the observation that binding of nitroimidazoles to cellular macromolecules occurs as a result of hypoxia-dependent bioreduction by cellular nitroreductases. Nitroimidazole-binding techniques provide measurements of hypoxia to virtually
Insulin receptor, IRS1, IRS2, INSIG1, INSIG2, RRAD, and BAIAP2 gene expressions in glioma U87 cells with ERN1 loss of function: effect of hypoxia and glutamine or glucose deprivation.

OBJECTIVE
The purpose of this study was to examine: 1) the association between the expression of the insulin receptor (INSR), insulin receptor substrate 1 (IRS1) and 2 (IRS2), insulin inducible gene 1 (INSIG1) and 2 (INSIG2), Ras-related associated with diabetes (RRAD), and brain-specific

Our previous study demonstrated that mutant IkappaBalpha (IkappaBalphaM) could inhibit glioma angiogenesis and tumorigenesis through the downregulation of vascular endothelial growth factor (VEGF) and IL-8. However, the pathways involved in VEGF expression are not well understood. Growing evidence

BACKGROUND
Hypoxia-tolerant human glioma cells reduce oxygen consumption rate in response to oxygen deficit, a defense mechanism that contributes to survival under moderately hypoxic conditions. In contrast, hypoxia-sensitive cells lack this ability. As it has been previously shown that
Procollagen-lysine 2-oxoglutarate 5-dioxygenase 2 promotes hypoxia-induced glioma migration and invasion.

Poor prognosis of glioblastoma multiforme is strongly associated with the ability of tumor cells to invade the brain parenchyma, which is believed to be the major factor responsible for glioblastoma recurrence. Therefore, identifying the molecular mechanisms driving invasion may lead to the
