Glioblastoma multiforme (GBM) is one of the most common brain tumors. Chemotherapy, radiotherapy and surgical resection are methods used in GBM treatment, however, investigation possible anticancer effects low-toxicity natural products on various cancer cells, including GBM, leads to promising results. In this study, it was aimed investigate effect tomentosin, which a sesquiterpene lactone, U87...

Glioblastoma (GBM) is a highly heterogeneous type of tumor characterized by genomic and signaling abnormalities affecting pathways involved in control of cell fate, including tumor-suppressor- and growth factor-regulated pathways. An aberrant miRNA expression has been observed in GBM, being associated with impaired cellular functions resulting in malignant transformation, proliferation and inva...

Glioblastoma, the most malignant form of brain cancer, is responsible for 23% of primary brain tumors and has extremely poor outcome. Confounding the clinical management of glioblastomas is the extreme local invasiveness of these cancer cells. The mechanisms that govern invasion are poorly understood. In order to gain insight into glioblastoma invasion, we conducted experiments on the patterns ...

BACKGROUND Interferon Regulatory Factor 7 (IRF7) is associated with chronic inflammation initiated by the activation of microglia. However it remains poorly defined how IRF7 activates microglia to initiate inflammatory microenvironment, and thus promotes the growth and malignancy of glioblastoma multiforme (GBM). This study investigated the role of IRF7 expression in microglia which increases G...

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...

To elucidate the anti-tumor effects and molecular mechanisms of ING5 on glioma cells, we overexpressed it in U87 cells, and examined the phenotypes and their relevant molecules. It was found that ING5 overexpression suppressed proliferation, energy metabolism, migration, invasion, and induced G2/M arrest, apoptosis, dedifferentiation, senescence, mesenchymal- epithelial transition and chemoresi...

PURPOSE Glioblastoma multiforme (GBM) is an aggressive primary brain tumor that is radio-resistant and recurs despite aggressive surgery, chemo, and radiotherapy. Autotaxin (ATX) is over expressed in various cancers including GBM and is implicated in tumor progression, invasion, and angiogenesis. Using the ATX specific inhibitor, PF-8380, we studied ATX as a potential target to enhance radiosen...

Promoter hypermethylation and histone deacetylation are common epigenetic mechanisms implicated in the transcriptional silencing of tumor suppressor genes in human cancer. We treated two immortalized glioma cell lines, T98 and U87, and 10 patient-derived primary glioma cell lines with trichostatin A (TSA), a histone deacetylase inhibitor, or 5-aza-2'-deoxycytidine (5-AzaC), a DNA methyltransfer...
