U87-derived stem-like cells (U87-SLCs) were cultured using serum-free stem cell media and identified by both biological behaviors and markers. Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) and paclitaxel (PX), in combination or alone, was used to treat U87-MG human glioma cells (U87 cells) or U87-SLCs. The results showed that TRAIL/PX cannot only synergistically inhibit ...

A novel 72 nt small nucleolar RNA (snoRNA) called U87 was found in rat liver cells. This RNA possesses the features of C/D box snoRNA family: boxes C, D 0, C 0, D, and 11 nt antisense element complementary to 28S ribosomal RNA (rRNA). The vast majority of C/D box snoRNAs direct site-specific 2 0-O-ribose methylation of rRNAs. U87 RNA is suggested to be involved in 2 0-O-methylation of a G3468 r...

Objective(s): Exosomes are endogenous nanovesicles act as intercellular communication tools which have been considered to utilize as drug delivery systems. As transporting therapeutic molecules into brain has obstacles, preparing exosomes which have the potential to pass through its barriers is great challenge. Methods: Exosomes isolated from cell culture media of U87 glioblastoma ...

In the previous study fifteen jatrophane diterpenes were isolated from Euphorbia nicaeensis latex. Fourteen of them have been shown to be potent P-glycoprotein (P-gp) inhibitor in two MDR cancer cells (NCI-H460/R and DLD1-TxR). The aim this was determine whether which can root plant, then examine their inhibition power on selected cell lines (NCI- -H460, DLD1, U87, NCI-H460/R, DLD1-TxR U87-TxR)...

Lissencephaly-1 (Lis1) protein is a dynein-binding protein involved in neural stem cell division, morphogenesis and motility. To determine whether Lis1 is a key factor in glioblastoma, we evaluated its expression and function in CD133+ glioblastoma cells. Global, Lis1 gene expression is similar in glioblastoma and normal samples. Interestingly, immunohistochemistry data indicate increased Lis1 ...

BACKGROUND Glioblastoma multiforme, a World Health Organization grade IV glioma, has a poor prognosis in humans despite current treatment options. Here, we present magnetic resonance imaging (MRI) data regarding the regression of aggressive rat F98 gliomas and human U87 glioma xenografts after treatment with the nitrone compound OKN-007, a disulfonyl derivative of α-phenyl-tert-butyl nitrone. ...

OBJECTIVE To investigate the role of 188Re in human sodium iodide symporter (hNIS) theranostic gene-mediated human glioma imaging and therapy in model mice. METHODS The human glioma cell line U87 was transfected with recombinant lentivirus encoding the hNIS gene under the control of cytomegalovirus promoter (U87-hNIS). The uptake and efflux of 188Re were determined after incubating the cells ...

Glioblastoma multiforme is the most lethal of brain cancer, and it comprises a heterogeneous mixture of functionally distinct cancer cells that affect tumor progression. We examined the U87, U251, and U373 malignant cell lines as in vitro models to determine the impact of cellular cross-talk on their phenotypic alterations in co-cultures. These cells were also studied at the transcriptome level...

Like the anti-angiogenic strategy, anti-vascular mimicry is considered as a novel targeting strategy for glioma. In the present study, we used NGR as a targeting ligand and prepared NGR-modified liposomes containing combretastatin A4 (NGR-SSL-CA4) in order to evaluate their potential targeting of glioma tumor cells and vasculogenic mimicry (VM) formed by glioma cells as well as their anti-VM ac...

Autophagy, or programmed cell death type II, is one of the responses of cancer cells to various therapies, including ionizing radiation. Recently, we have shown that radiation induces autophagy, but not apoptosis, in various malignant glioma cell lines. Autophagy is mainly regulated by the mammalian target of rapamycin (mTOR) pathway. The Akt/ mTOR pathway also mediates oncogenesis and radiores...
