Glioblastoma is the most lethal brain tumour with a poor prognosis. Cancer stem cells (CSC) were proposed to be the most aggressive cells allowing brain tumour recurrence and aggressiveness. Current challenge is to determine CSC signature to characterize these cells and to develop new therapeutics. In a previous work, we achieved a screening of glycosylation-related genes to characterize specif...
Abstract In spite of relentless efforts to devise new treatment strategies, primary glioblastomas invariably recur as aggressive, therapy-resistant relapses and patients rapidly succumb to these tumors. Many therapeutic agents are first tested in clinical trials involving recurrent glioblastomas. Remarkably, however, fundamental knowledge on the biology of recurrent glioblastoma is just slowly ...
Tumor cells rely preferentially on anaerobic glycolysis rather than on respiration for ATP generation, a phenomenon known as the Warburg effect. We explored the effects of glucose withdrawal on glioblastoma multiforme-derived cell lines and their nontransformed counterparts, normal human astrocytes. We found that glucose withdrawal induces extensive apoptosis in glioblastoma multiforme cells bu...
Glioblastoma is aggressive, highly infiltrating, and the most frequent malignant form of brain cancer. With a median survival time of only 14.6 months, when treated with the standard of care, it is essential to find new therapeutic options. A specific CDK4/6 inhibitor, PD0332991, obtained accelerated approval from the Food and Drug Administration for the treatment of patients with advanced estr...
Background: The most malignant form of infiltrating astrocytoma, glioblastoma multiforme (GBM), is one of the most aggressive human cancers. Foretinib diminished GBM cell invasion by downregulating the expression of matrix metalloproteinase 2 (MMP2). The study aimed to examine the anti-tumor activity of foretinib and to test its effect on MMP2 expression in T98 cells. Materials and methods: T9...
UNLABELLED INTRODUCTION Cerebellar glioblastoma is an uncommon adult lesion. The pathogeny and prognosis of cerebellar glioblastoma are still incompletely elucidated. CASE PRESENTATION We report the case of a 19-year-old Moroccan woman. A neurologic examination revealed the presence of cerebellar signs. A diagnosis of cerebellar glioblastoma is rarely made before surgery. An encephalic com...
Treatment for Glioblastoma with Carboplatin, Oral Etoposide and Interferon β (CEI): A Phase II Trial
Gioblastoma is one of the most refractory tumors in central nervous system, and the prognosis remains poor. Temozolomide is a first-line agent for newly-diagnosed glioblastoma, but chemotherapy for recurrent or temozolomide-resistant glioblastoma has not been established. To determine whether chemotherapy with carboplatin, oral etoposide, and interferon β (CEI) prolongs survivals of patients be...
Glioblastoma represents extreme anaplasia in astrocytic tumors. In spite of this aggressiveness, extracranial metastasis of glioblastoma is very rare and has been documented in only a few patients in the literature. In this article, a 30-year-old woman with secondary glioblastoma associated with extracranial distant metastasis was presented. In September 2008, an intracranial lesion in the left...
Phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K) plays a critical role in the pathogenesis of cancer including glioblastoma, the most common and aggressive form of brain cancer. Targeting the PI3K pathway to treat glioblastoma has been tested in the clinic with modest effect. In light of the recent finding that PI3K catalytic subunits (PIK3CA/p110α, PIK3CB/p110β, PIK3CD/p110δ, and PIK3CG/p...
Calcium signaling is important in many signaling processes in cancer cell proliferation and motility including in deadly glioblastomas of the brain that aggressively invade neighboring tissue. We hypothesized that disturbing Ca(2+) signaling pathways might decrease the invasive behavior of giloblastoma, extending survival. Evaluating a panel of small-molecule modulators of Ca(2+) signaling, we ...
