The chicken chorioallantoic membrane was used to select variant tumor cell subpopulations from the murine melanoma B16-BL6 and the rat glioma C6 cell lines. Tumor cells were deposited on the chicken chorioallantoic membrane of eggs 10 days postfertilization. Upon hatching, chickens were autopsied, and organs were removed, minced, and implanted s.c. in C57BL/6J mice (for melanoma) or nude mice (...

The combination of Endostatin (ES) and Herpes Simplex Virus thymidine kinase (HSV-TK) gene therapy is known to have antitumor activity in bladder cancer. The potential effect of ES and TK therapy in glioma has not yet been investigated. In this study, pTK-internal ribosome entry site (IRES), pIRES-ES, and pTK-IRES-ES plasmids were constructed; pIRES empty vector served as the negative control. ...

BACKGROUND Glioblastoma is a common and aggressive type of primary brain tumor. Several anticancer drugs affect GBM (glioblastoma multiforme) cells on cell growth and morphology. Taxol is one of the widely used antineoplastic drugs against many types of solid tumors, such as breast, ovarian, and prostate cancers. However, the effect of taxol on GBM cells remains unclear and requires further inv...

BACKGROUND/OBJECTIVES Yacon (Samallanthus sonchifolius), a common edible plant grown throughout the world, is well known for its antidiabetic properties. It is also known to have several other pharmacological properties including anti-inflammatory, anti-oxidant, anti-allergic, and anti-cancer effects. To date, the effect of yacon on gliomas has not been studied. In this study, we investigated t...

OBJECTIVE To evaluate the impact of Photolon on cytostatic and cytotoxic effects of therapeutic range ultrasound in C6 glioma cells. METHODS C6 glioma cells in suspension or monolayer cell culture were exposed to ultrasound (880 kHz, 0.2-0.7 W/cm2) in the presence or absence of Photolon at the concentration of 1 μg/ml in the culture medium, and then cell viability was evaluated. RESULTS Pho...

BACKGROUND Superparamagnetic iron oxide nanoparticles (SPIONs), due to their unique magnetic properties, have the ability to function both as magnetic resonance (MR) contrast agents, and can be used for thermotherapy. SPIONs conjugated to the heat shock protein Hsp70 that selectively binds to the CD40 receptor present on glioma cells, could be used for MR contrast enhancement of experimental C6...

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...

Although the combination of herpes simplex virus type 1 (HSV-1) thymidine kinase (TK) with ganciclovir (GCV) has been shown as a promising suicide gene treatment strategy for glioma, the almost immunodepressive dose of GCV required for its adequate in vivo efficacy has hampered its further clinical application. Therefore, In order to reduce the GCV dose required, we aim to compare the therapeut...

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 ...
