We found that glioblastoma resistance to gefitinib may be mediated by an adaptive pro-survival TNFα-JNK-Axl signaling axis, and that high TNFα levels in the glioblastoma microenvironment may further intensify primary resistance.
The effect of a TNFα-producing adipose tissue-derived MSC (AT-MSC/hTNFα) was tested on the tumour cell lines of different origins: melanoma (A375), breast carcinoma (SKBR3, MDA-MB-231), colon carcinoma (HT29), ovarian carcinoma (SKOV3) and glioblastoma (U87-MG) cells.
In in vitro study, HCMV infection induced the expression of interleukin 6 and tumor necrosis factor-α in human glioblastoma U87 MG (U87) cells and human umbilical vein endothelial cells (HUVECs).
Growth inhibition and radiosensitization of glioblastoma and lung cancer cells by small interfering RNA silencing of tumor necrosis factor receptor-associated factor 2.
The antiapoptotic protein FLIP(S) is a key suppressor of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-induced apoptosis in human glioblastoma multiforme (GBM) cells.
Human mesenchymal stem cell (MSC)-based tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) gene delivery is regarded as an effective treatment for glioblastoma (GBM).
Our findings provide a possible explanation for the failures of anti-EGFR therapy in GBM and suggest a new approach to the treatment of EGFR-expressing GBM using a combination of EGFR and TNF inhibition.
We show that 3TSR upregulates death receptor (DR) 4/5 expression in a CD36-dependent manner and primes resistant GBMs to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-induced caspase-8/3/7 mediated apoptosis.
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a novel cancer therapeutic agent for GBM because of its capability of inducing apoptosis in glioma cells.
Serial imaging showed that h-iNSC<sup>TE</sup> delivery of the proapoptotic agent tumor necrosis factor-α-related apoptosis-inducing ligand (TRAIL) reduced the size of solid human GBM xenografts 250-fold in 3 weeks and prolonged median survival from 22 to 49 days.
Apoptosis in human glioblastoma cells produced using embryonic stem cell-derived astrocytes expressing tumor necrosis factor-related apoptosis-inducing ligand.
We created constitutive and regulatable miR-7 expression vectors and utilized pharmacological inhibition of caspases and genetic loss of function to study the effect of forced expression of miR-7 on death receptor (DR) pathways in a cohort of GBM with established resistance to tumor necrosis factor apoptosis inducing ligand (TRAIL) and in patient-derived primary GBM stem cell (GSC) lines.
The highest mean values of PHLPP1 mRNA and protein were found in non-glioma brain tissues whereas the lowest mean values were found in those in glioblastoma with an increase of TNF-α, IL-17, IL-1β (p<0.05).
As both TNFalpha and oxidative stress independently play role in regulating cytoskeletal organization and cell survival pathways we investigated whether TNFalpha mediated oxidative stress regulates responses that offer survival advantages to glioblastoma cells.
The TNF receptor superfamily member Fn14 is overexpressed by many solid tumor types, including glioblastoma (GBM), the most common and lethal form of adult brain cancer.
Treatment of human U251 and TG1 glioblastoma cells with both flavonoids also modulated negatively the expression of mRNA for IL-6 and IL-10 and positively the expression of mRNA for TNF characterizing changes to the immune regulatory profile.
Modulation of CCAAT/enhancer binding protein homologous protein (CHOP)-dependent DR5 expression by nelfinavir sensitizes glioblastoma multiforme cells to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL).
Our prior work has demonstrated an important role for the tumor necrosis factor-like weak inducer of apoptosis (TWEAK) receptor fibroblast growth factor-inducible 14 (Fn14) in GBM pathobiology.
