BACKGROUND Glioma stem cell (GSC) hypothesis posits that a subpopulation of cells within gliomas have true clonogenic and tumorigenic potential. Significantly, a more controversial correlate to GSC is that cells in different culture conditions might display distinct stem cell properties. Considering these possibilities, we applied an approach comparing stem cell characteristics of C6 glioma cel...
Hydroxyapatite (HA) nanoparticles have been reported to exhibit anti-tumor effects on various human cancers, but the effects of HA on glioma cells remain unclear. The aim of this study was to explore whether HA can inhibit the proliferation and induce the apoptosis of C6 cells. Use of the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay indicated that HA induced C6 cell ...
Tetramethylpyrazine (TMP) is the major component extracted from the Chinese herb Chuanxiong. Increasing numbers of studies have indicated that tetramethylpyrazine hydrochloride (TMPH) has anticancer effects. However, the molecular mechanisms underlying the actions of TMPH have not been fully elucidated. In this study, using real-time RT-PCR and we...
Transit of human neural stem cells, ReNcell CX, through the blood brain barrier (BBB) was evaluated in an in vitro model of BBB and in nude mice. The BBB model was based on rat brain microvascular endothelial cells (RBMECs) cultured on Millicell inserts bathed from the basolateral side with conditioned media (CM) from astrocytes or glioma C6 cells. Glioma C6 CM induced a significant transendoth...
The purpose of the study was to investigate whether carvedilol has an antiproliferative effect alone and whether carvedilol provides an additive, synergistic or antagonistic effect on imatinib mesylate-induced cytotoxicity in both C6 glioma monolayer and spheroid culture. The C6 rat glioma chemoresistant experimental brain tumour cell line, that is notoriously difficult to treat with combinatio...
Expression of angiogenic factors such as vascular endothelial growth factor (VEGF) under conditions of cell stress involves both transcriptional and translational events, as well as an important role for inducible endoplasmic reticulum (ER) chaperones. Coexpression of VEGF and 150-kDa oxygen-regulated protein (ORP), a novel ER chaperone, in human glioblastoma suggested a link between angiogenes...
Reserpine has enhanced the cytotoxicity of 1 (4-amino-2-methyl-5-pyrimidinyl) methyl-3-(2 chloroethyl)-3-nitrosourea hydrochloride (ACNU) in both ACNU-resistant sublines of C6 and 9L glioma cells (C6/ACNU, 9L/ACNU) and could completely overcome ACNU resistance in vitro. When reserpine was added to the culture in the concentration of 10ƒÊM, the concentrations of drug required for 50% inhibition ...

There are conflicting results concerning the receptor subtype(s) involved in calcium-mediated endothelin signaling in the glial cells. In order to elucidate the role of endothelin A and B receptors in these processes, we have studied the effect of a complex spectrum of endothelin receptor ligands on intracellular calcium concentration changes in proliferating and differentiated C6 rat glioma ce...
Glioma is the most common type of brain tumors in adults, and treatment of high-grade gliomas is still palliative. Studies to date have revealed only modest effect in attenuating growth of these tumors with single agent therapy, but combination treatment appears to be more effective. Cyclophilin A (CypA), a target of immunosuppressive drugs cyclosporin A (CsA) and sanglifehrin A (SFA), is an in...
