Glioblastoma multiforme (GBM) is a malignant primary type of brain cancer with high proliferation and metastasis rates due to involvement of the microglial cell. It is resistant against available chemotherapy. Many strategic protocols have been developed but prognosis and patient life has not improved substantially. In this study, the anti-metastatic and antioxidant effect of fatty acids from C...
OBJECT The authors studied the effect of gender and hormonal status on survival in nude rats implanted with human glioblastoma multiforme (GBM) cell lines. METHODS Nude rats received intracerebral implants of either wild-type U87MG cells or U87MG cells transfected with the gene for endothelin-1 (U87/ET-1). In the initial study, survival was compared in males and females for each of the two ce...
The marine ecosystem is a vast but largely untapped resource for potential naturally based medicines. We tested 15 compounds derived from organisms found in the Caribbean Sea (14 gorgonian octocoral-derived compounds and one sponge-derived compound) for their anticancer effects on human malignant glioma U87-MG and U373-MG cells. Eupalmerin acetate (EPA) was chosen as the lead compound based on ...
Cruz-Munoz and colleagues (1) state that their findings represent the first report of spontaneous central nervous system metastases generated from primary tumors of any human cancer in mice, which heritably maintain this phenotype. It should be noted, however, that with the use of imaging based on green fluorescent protein (GFP) expression in tumor cells (2), we have observed spontaneous metast...
Glioblastoma (GBM) is the most common and lethal primary intracranial tumor. Actin cytoskeleton regulator Arp2/3 complex stimulates glioma cell motility and migration, and thus triggers tumor invasion. However, little is known regarding the role of actin cytoskeleton in maintaining the stem cell phenotype. Here, we showed that Arp2/3 complex improved stem cell phenotype maintenance through sust...
Zebrafish (Danio rerio) is becoming an increasingly popular vertebrate cancer model. In this study, we established a xenotransplanted zebrafish embryo glioma model to further investigate the molecular mechanisms of tumor angiogenesis. We find that the glioma cell line U87 can survive, proliferate and induce additional SIV branches in zebrafish emb...
This study aimed to improve delivery of lomustine as a chemotherapeutic agent and to increase its uptake by U87-MG cancer cells via synthesizes LN-FA-PG-SPIONs (lomustine loaded polyglycerol coated superparamagnetic iron oxide nanoparticles conjugated with folic acid). Nanoparticles were synthesized by thermal decomposition method and characterized using TEM (transmission microscope), FTIR (Fou...
shiga toxins (stxs) are bacterial virulence factors produced by shigella dysenteriae serotype 1 and escherichia coli strains. stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. additionally, stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. the inflammatory cyto...
Glioblastoma is associated with a poor overall survival despite new treatment advances. Antiangiogenic strategies targeting VEGF based on tyrosine kinase inhibitors (TKIs) are currently undergoing extensive research for the treatment of glioma.Herein we demonstrated that the TKI axitinib induces DNA damage response (DDR) characterized by γ-H2AX phosphorylation and Chk1 kinase activation leading...
زمینه و هدف: ساخت و ترکیب داروهای جدید گیاهی و شیمیایی علیه بیماری هایی مثل سرطان، از جمله تلاش های مهم سال های اخیر محسوب می شود. ترکیبات ترپنی از جمله ترکیبات مهمی هستند که خواص بیولوژیکی و فارماکولوژیکی متعددی دارند، اما به دلیل حلالیت کم آن ها در محلول های آبی کمتر مورد توجه بوده اند. سیکلودکسترین ها نیز نانوکپسول های طبیعی تشکیل شده از واحدهای گلوکزی هستند که می توانند ایجاد نانوحفره نماین...
