Glioblastoma (GBM) is the most common and aggressive form of primary brain tumor with a median survival of 12-15 months, and the mechanisms underlying GBM tumor progression remain largely elusive. Given the importance of tumor niche signaling in driving GBM progression, there is a strong need to develop in vitro models to facilitate analysis of brain tumor cell-niche interactions in a physiolog...

cancer is the second leading cause of death in the world. despite advances in the diagnosis and treatment, overall survival of patients still remains poor. hence, there is an urgent need for development of new anticancer agents. considering promising biological activity of 1,3,4-thiadiazole derivatives, in the present study, synthesis and cytotoxicity assessment of new derivatives of this ring ...

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...

Glioblastoma (GBM), the most common and aggressive brain tumor in the central nervous system, remains a lethal diagnosis with a median survival of < 15 months. Aberrant expression of the TRPM7 channel has been linked to GBM functions. In this study, using the human GBM cell line U87, we evaluated the TRPM7 activator naltriben on GBM viability, migration, and invasiveness. First, using the whole...

Malignant glioma represents the most common primary adult brain tumor in Western industrialized countries. Despite aggressive treatment modalities, the median survival duration for patients with glioblastoma multiforme (GBM), the highest grade malignant glioma, has not improved significantly over past decades. One promising approach to deal with GBM is the inactivation of proteins essential for...

N1,N11-diethylnorspermine (DENSPM), a polyamine analog that induces expression of spermidine/spermine N1-acetyltransferase (SSAT) and reduces polyamine levels in eukaryotic cells, has demonstrated anticancer effects in many cancer cell types. Gene expression of SSAT after treatment with DENSPM was measured in both U87 and LN229 cells using real-ti...

MiR-134 is a brain-enriched miRNA that plays an essential role in the development of the embryonic stem cell-orientated differentiation to central nervous system by suppression of Nanog and neural development (including neurons, cylindraxile and dendrites) and has been shown to be downregulated in oligodendrogliomas (ODG) and glioblastomas (GBM), suggesting its possible involvement in brain tum...

Abstract Tumor cells have different metabolism from normal cell, which is called as cancer metabolism. In cells, asparagine provided by synthetase (ASNS) aspartate. On the other hand, in tumor needed to be taken outside addition synthesized ASNS within because of rapid growth cells. Glioblastoma one aggressive brain tumors, and temozolomide frequently used. After glioblastoma acquire resistance...
