Recent therapeutic advances have improved standard treatment for patients with newly diagnosed glioblastoma. Unfortunately, even with these improvements, only a fraction of patients derive significant benefit and experience prolonged survival. These findings are consistent with long-standing clinical and recent molecular evidence that subtypes of glioblastoma exist with differing survival rates...

The human crk gene is translated into crkI and crkII by alternative splicing. crkII mRNA was detected both in normal brain and glioblastoma tissues, whereas crkI mRNA levels were quite low in normal brain and up-regulated in glioblastoma tissues. Expression of CrkI but not CrkII in glioblastoma U87MG cells induced transformation that stimulated cell migration and invasion concomitant with tyros...

Posterior fossa glioblastoma multiforme is a very rare childhood tumor with an extremely poor prognosis. There are only few cases of primary cerebellar glioblastoma described in the literature, and primary cerebellar glioblastoma presenting radiologically as a cerebellopontine angle mass lesion has not been reported previously. The authors report a multicentric glioblastoma multiforme in an 11-...

Abstract Glioblastoma (GBM) is the most common and deadliest primary tumor in adults, with current treatments having limited specific and efficient delivery of therapeutic drugs to tumor sites or cells. Therefore, the development of alternative treatment options is urgently needed. Stem cells are considered as ideal cellular vehicles for gene therapy against glioblastoma. In this paper, we revi...

Glioblastoma is the most common primary brain tumor in the adult and carries a poor prognosis with a median survival of only 14 months. Patients with glioblastoma are followed with MRI scans, but this technique has several limitations including low specificity to differentiate between tumor and treatment effect. Development of serum markers could significantly improve the care of glioblastoma p...

microRNAs are noncoding RNAs inhibiting expression of numerous target genes, and a few have been shown to act as oncogenes or tumor suppressors. We show that microRNA-7 (miR-7) is a potential tumor suppressor in glioblastoma targeting critical cancer pathways. miR-7 potently suppressed epidermal growth factor receptor expression, and furthermore it independently inhibited the Akt pathway via ta...

BACKGROUND Epigenetic silencing of tumor suppressor genes plays important role in gliomagenesis. Recently, GATA4 and DcR1 were suggested to be a tumor suppressor genes involved in tumorigenesis in various types of human cancers. However, up to now the methylation frequency of GATA4 and DcR1 genes has not been determined in glioblastoma. In this study, we investigated methylation of GATA4 and Dc...

BACKGROUND We have previously shown that the transcriptional coregulator NCoR represses astrocytic differentiation of neural stem cells, suggesting that NCoR could be a plausible target for differentiation therapy of glioblastoma. METHODS To study a putative role for NCoR in regulating glioblastoma cell characteristics, we used RNA-mediated knockdown followed by analysis of gene expression, p...

Glioblastoma is an aggressive tumor that occurs in both adult and pediatric patients and is known for its invasive quality and high rate of recurrence. Current therapies for glioblastoma result in high morbidity and dismal outcomes. The TAM subfamily of receptor tyrosine kinases includes Tyro3, Axl, and MerTK. Axl and MerTK exhibit little to no expression in normal brain but are highly expresse...

Amplification of the epidermal growth factor receptor (EGFR) gene is one of the most common oncogenic alterations in glioblastoma (45%) making it a prime target for therapy. However, small molecule inhibitors of the EGFR tyrosine kinase showed disappointing efficacy in clinical trials for glioblastoma. Here we aimed at investigating the molecular effects of the tyrosine kinase inhibitor gefitin...
