CD44 mediates human glioma cell adhesion and invasion in vitro.
Human gliomas are characterized by their invasion of normal brain structures irrespective of their grade of malignancy. Factors involved in the control of this invasive behavior are poorly documented. Human gliomas have also been found to express CD44 adhesion molecules. Expression of splice variants of CD44 has been correlated to metastasis in nonglial solid tumors. In this study, 8-microns po...
متن کاملExtracts from Glioma Tissues following Cryoablation Have Proapoptosis, Antiproliferation, and Anti-Invasion Effects on Glioma Cells
OBJECTIVE This study is to investigate the in vivo apoptotic processes in glioma tissues following cryoablation and the effects of glioma tissue extracts on GL261 glioma cells in vitro. METHODS TUNEL and flow cytometry analysis were performed to detect the apoptotic processes in the glioma tissues following cryoablation and in the GL261 cells treated with cryoablated tumor extracts. The scrat...
متن کاملInhibition of Glioma Cell Lysosome Exocytosis Inhibits Glioma Invasion
Cancer cells invade by secreting enzymes that degrade the extracellular matrix and these are sequestered in lysosomal vesicles. In this study, the effects of the selective lysosome lysing drug GPN and the lysosome exocytosis inhibitor vacuolin-1 on lysosome exocytosis were studied to determine their effect on glioma cell migration and invasion. Both GPN and vacuolin-1 evidently inhibited migrat...
متن کاملMathematical Model for Glioma Cell Invasion
Experimental observations suggest that in the vicinity of the glioma-host interaction zone glioma cells secrete MMPs that dissolve the ECM composition and disturb the balance of the brain tissue [3]. In order to restore the natural balance, healthy brain cells try and produce more ECM components as well as secreting tissue inhibitor of the MMPs (TIMPs) [12]. In this paper we present a mathemati...
متن کاملMiR-203 sensitizes glioma cells to temozolomide and inhibits glioma cell invasion by targeting E2F3.
Glioma is the most common malignant and fatal primary tumor in the central nervous system in adults. Recent data has suggested a profound role for microRNAs (miRs) in cancer progression. The present study demonstrated, via quantitative polymerase chain reaction (qPCR) analysis, that miR-203 expression was markedly lower in highly invasive U87MG glioma cells and glioma tissues. Wound healing and...
