Glioblastoma (GBM) is the most aggressive and common malignant brain tumour in adults. A well-known hallmark of GMB and many other tumours is aerobic glycolysis. MicroRNAs (miRNAs) are a class of short nonprotein coding sequences that exert posttranscriptional controls on gene expression and represent critical regulators of aerobic glycolysis in GBM. In GBM, miRNAs regulate the expression of gl...

An interaction between ribosomal protein S3 (rpS3) and nuclear factor kappa B or macrophage migration inhibitory factor in non-small-cell lung cancer is responsible for radioresistance. However, the role of rpS3 in glioblastoma (GBM) has not been investigated to date. Here we found that in irradiated GBM cells, rpS3 translocated into the nucleus and was subsequently ubiquitinated by ring finger...

BACKGROUND Glioblastoma (GBM) is a highly invasive, aggressive, and incurable brain tumor. Genetic factors play important roles in GBM risk. The aim of this study was to elucidate the influence of gene polymorphism on GBM susceptibility. MATERIAL AND METHODS In this case-control study, we included 72 GBM patients and 320 healthy controls to analyze the association between 29 single-nucleotide...

BACKGROUND Glioblastoma (GBM) is a malignant brain tumor with dismal prognosis. GBM patients have a median survival of less than 2 years. GBM is characterized by fast cell proliferation, infiltrative migration, and by the induction of angiogenesis. MicroRNAs and polycomb group (PcG) proteins have emerged as important regulators of gene expression. METHODS Here we determined that miR-101 is do...

OBJECTIVE In this study, we investigated whether circulating microRNA-137 (miR-137) could be a potential biomarker for patients with glioblastoma (GBM). PATIENTS AND METHODS Serum samples were collected from 64 GBM patients and 64 healthy controls. The expression level of circulating miR-137 was compared by quantitative RT-PCR. Among GBM patients, circulating miR-137 was compared between pati...

wnloaded blastoma multiforme (GBM) has an abysmal prognosis. We now know that the epidermal growth receptor (EGFR) signaling pathway and the loss of function of the tumor suppressor genes p16Ink4a/ F and PTEN play a crucial role in GBM pathogenesis: initiating the early stages of tumor development, ning tumor growth, promoting infiltration, and mediating resistance to therapy. We have recently ...

Glioblastoma multiforme (GBM) is a devastating tumour with abysmal prognoses. We desperately need novel approaches to understand GBM biology and therapeutic vulnerabilities. Extracellular vesicles (EVs) are membrane-enclosed nanospheres released locally and systemically by all cells, including tumours, with tremendous potential for intercellular communication. Tumour EVs manipulate their local ...

BACKGROUND Glioblastomas (GBM) present a high cellular heterogeneity with conspicuous necrotic regions associated with hypoxia, which is related to tumor aggressiveness. GBM tumors exhibit high glycolytic metabolism with increased lactate production that is extruded to the tumor microenvironment through monocarboxylate transporters (MCTs). While hypoxia-mediated regulation of MCT4 has been char...

BACKGROUND Glioblastoma multiforme (GBM) is the most lethal type of adult brain cancer and performs outrageous growth and resistance regardless of adjuvant chemotherapies, eventually contributing to tumor recurrence and poor outcomes. Considering the common heterogeneity of cancer cells, the imbalanced regulatory mechanism could be switched on/off and contribute to drug resistance. Moreover, th...

Glioblastomas (GBM) are paradigmatic for the investigation of cancer stem cells (CSC) in solid tumors. Recently, the discovery of CD133- CSC in addition to CD133+ CSC has substantially added to our understanding of the complexity of GBM CSC. This review gives an overview on our current knowledge on CD133- cells in GBM and describes five different hypothesizes on the nature of CD133- cells in GB...
