BACKGROUND Quercetin has been shown to induce apoptosis in a number of cancer cell lines, but a quercetin-loaded nanoliposomal formulation with enhanced antitumor activity in C6 glioma cells and its effect on cancer cell death has not been well studied. The aim of this study was to examine if quercetin-loaded liposomes (QUE-NL) has enhanced cytotoxic effects and if such effects involve type III...

BACKGROUND The demand for the chemopreventive drug from the plant source is increasing in recent times, owing to its various biological activities without any adverse effect. The intention of this current study was to examine the anti-glioma effect of Withaferin A (WFA) on C6 glioma cell line model. MATERIALS AND METHODS C6 glioma cells were administrated with different concentration of WFA (...

OBJECTIVES: The purpose of this study was to compare the effects of neurotrophic cytokines on the JAK/STAT transcription factors and the immediate early gene, c-fos, in C6 glioma cells and in primary astrocyte cultures. METHODS: In this study we compared the effects of interleukin 6, leukemia inhibitory factor and interferon gamma on C6 glioma cells and on primary astrocyte cultures using elect...

Although temozolomide (TMZ) is the most effective chemotherapy agent for glioma, chemotherapy resistance has limited its clinical use. Fluoxetine (FLT), which is widely used in cancer-related depression, has exhibited potent anticancer properties in different cancer cell types. The aim of this study was i) to evaluate the antitumor mechanism of FLT, and ii) to further evaluate the effects of a ...

PURPOSE The study reported here examined the effect of hematoporphyrin monomethyl ether (HMME)-mediated sonodynamic therapy (SDT) on C6 gliomas implanted in rat brains. METHODS Two weeks after inoculation, glioma development was evaluated by measuring tumor volume using a 1.5 T magnetic resonance imager. Rats that had a well-developed C6 glioma (usually when the tumor diameter reached 3-5 mm)...

Dichloroacetate (DCA), a small molecule mitochondria-targeting agent, can penetrate the blood-brain barrier, showing potential therapeutic effects on brain tumors. Considering the effects of DCA on tumor cellular metabolism, penetrating across the blood-brain barrier, as well as having potential antitumor activity on brain tumors, the purpose of this study is to investigate the antitumor activi...

glioma, as a primary tumor of central nervous system, is the main cause of death in patients with brain cancer. therefore, development of an efficient strategy for treatment of glioma is worthy. the aim of the current study was to develop a srl peptide-coated dendrimer as a novel dual gene delivery system for targeting the lrp receptor, an up-regulated gene in both bbb and glioma cells. to perf...

Rat C6 glioma is a chemo-resistant experimental brain tumor that is difficult to treat with various drug combinations. Previous studies suggested that imatinib mesylate (Gleevec) is effective in pre-clinical trials for glioblastoma. Also, chlorimipramine (Anafranil) is an anti-depressant drug in use in the clinic and shown to have anti-neoplastic activity. We hypothesized that treatment of resi...

Edelfosine is the prototype molecule of a family of anticancer drugs collectively known as synthetic alkyl-lysophospholipids. This drug holds promise as a selective antitumor agent, and a number of preclinical assays are in progress. In this study, we observe the accumulation of edelfosine in brain tissue after its oral administration in Compritol® and Precirol® lipid nanoparticles (LN). The hi...

This study aimed at combining an iron-based, steady-state, vessel size index magnetic resonance imaging (VSI MRI) approach, and a gadolinium (Gd)-based, dynamic contrast-enhanced MRI approach (DCE MRI) to characterize tumoral microvasculature. Rats bearing an orthotopic glioma (C6, n=14 and RG2, n=6) underwent DCE MRI and combined VSI and DCE MRI 4 h later, at 2.35 T. Gd-DOTA (200 mumol of Gd p...
