Regulation of Integrated Stress Response Sensitizes U87MG Glioblastoma Cells to Temozolomide through the Mitochondrial Apoptosis Pathway.

Glioblastomas are the most frequently diagnosed and worst primary malignancy of the central nervous system, with very poor prognosis. The first-line anti-glioma drug temozolomide shows decreasing therapeutic efficacy as treatment progresses. As the integrated stress response (ISR) may be a resistance factor and severe stress might transform the protective effect of the ISR into a damage effect, pharmacological regulation of ISR may be an effective way to sensitize glioma to temozolomide. The aim of the pres...

High-dose fotemustine in temozolomide-pretreated glioblastoma multiforme patients: A phase I/II trial.

Glioblastoma multiforme (GBM) is a rare and deadly disease, with a reported average incidence rate of 3.19 cases per 100,000 inhabitants. Fotemustine, a third-generation nitrosourea with an alanine phosphor carrier that facilitates cellular penetration, has been extensively investigated in the setting of recurrent/progressive disease after initial treatment. Fotemustine is usually administered following a schedule consisting of 3 doses every week, followed by maintenance doses administered every 3 weeks.

Effects of sequentially applied single and combined temozolomide, hydroxychloroquine and AT101 treatment in a long-term stimulation glioblastoma in vitro model.

Glioblastoma multiforme (GBM) is a poorly curable disease due to its heterogeneity that enables single cells to survive treatment regimen and initiate tumor regrowth. Although some progress in therapy has been achieved in the last years, the efficient treatment of GBMs is still a clinical challenge. Besides the standard therapeutic drug temozolomide (TMZ), quinoline-based antimalarial drugs such as hydroxychloroquine (HCQ) and BH3 mimetics such as AT101 were considered as possible drugs for GBM therapy.

Interim Results of a Phase II Study of Hypofractionated Radiotherapy with Concurrent Temozolomide Followed by Adjuvant Temozolomide in Patients over 70 Years Old with Newly Diagnosed Glioblastoma.

In this phase II study, we investigate clinical outcomes and tolerability of hypofractionated radiotherapy (HRT) combined with temozolomide (TMZ) to treat elderly patients with glioblastoma (GBM).

Receptor-mediated PLGA nanoparticles for Glioblastoma Multiforme treatment.

Glioblastoma multiforme is the most lethal type of brain tumor and the established therapy only extends patients survival to approximately one year. Its first-line treatment is based on of chemotherapy with the alkylating agent temozolomide (TMZ). As many other chemotherapeutic drugs, TMZ presents several limitations as high toxicity and low bioavailability. The delivery of TMZ using poly(lactic-co-glycolic acid) nanoparticles is proposed in this work. Stable nanoparticles functionalized with a OX26 type mo...

Role of Chimeric Antigen Receptor T Cell Therapy in Glioblastoma Multiforme.

Glioblastoma multiforme (GBM) is the most common primary malignant cancer of brain, which is extremely aggressive and carries a dreadful prognosis. Current treatment protocol runs around radiotherapy, surgical resection, and temozolomide with median overall survival of around 12-15 months. Due to its heterogeneity and mutational load, immunotherapy with chimeric antigen receptor (CAR) T cell therapy can be a promising treatment option for recurrent glioblastoma. Initial phase 1 studies have shown that this...

Down-regulation of MDR1 by Ad-DKK3 via Akt/NFκB pathways augments the anti-tumor effect of temozolomide in glioblastoma cells and a murine xenograft model.

Glioblastoma multiforme (GBM) is the most malignant of brain tumors. Acquired drug resistance is a major obstacle for successful treatment. Earlier studies reported that expression of the multiple drug resistance gene (MDR1) is regulated by YB-1 or NFκB via the JNK/c-Jun or Akt pathway. Over-expression of the Dickkopf (DKK) family member DKK3 by an adenovirus vector carrying DKK3 (Ad-DKK3) exerted anti-tumor effects and led to the activation of the JNK/c-Jun pathway. We investigated whether Ad-DKK3 augment...

Hypofractionated accelerated radiotherapy (HART) with concurrent and adjuvant temozolomide in newly diagnosed glioblastoma: a phase II randomized trial (HART-GBM trial).

Maximal safe surgical resection followed by adjuvant chemoradiation has been standard for newly diagnosed glioblastoma multiforme (GBM). Hypofractionated accelerated radiotherapy (HART) has the potential to improve outcome as it reduces the overall treatment time and increases the biological effective dose.

The TNF Receptor Family Member Fn14 is Highly Expressed in Recurrent Glioblastoma (GBM) and in GBM Patient-Derived Xenografts With Acquired Temozolomide Resistance.

Glioblastoma (GBM) is a difficult-to-treat brain cancer that nearly uniformly recurs, and recurrent tumors are largely therapy-resistant. Our prior work has demonstrated an important role for the TWEAK receptor Fn14 in GBM patho-biology. In this study, we investigated Fn14 expression in recurrent GBM and in the setting of temozolomide (TMZ) resistance.

One decade of glioblastoma multiforme surgery in 342 elderly patients: what have we learned?

Glioblastoma multiforme (GBM) is the most common malignant primary brain tumor in adults with peak incidence in patients older than 65 years. These patients are mostly underrepresented in clinical trials and often undertreated due to concomitant diseases. Recently, different therapeutic approaches for elderly patients with GBM were discussed. To date, there is no defined standard treatment. The aim of the present study is to evaluate the functional and oncological outcome in surgical treatment of elderly p...

Long non-coding RNA CASP5 promotes the malignant phenotypes of human glioblastoma multiforme.

Long non-coding RNAs (lncRNAs) have been demonstrated to be intensively involved in the development of various carcinomas, including glioblastoma multiforme (GBM). However, only a few of them have been well characterized. LncRNA CASP5 have been found to be up-regulated in GBM tissues compared with normal tissues in a microarray-based lncRNA profiling study. In the present study, we further explored the biological role of lncRNA CASP5 in GBM.

Cytotoxicity of Ultraviolet-C Radiation on a Heterogeneous Population of Human Glioblastoma Multiforme Cells: Meta-analysis.

Current treatment strategies for glioblastoma multiforme are limited due to early recurrence and heterogeneity of the cell population that causes a varied response to treatment. Ultraviolet-C (UVC) radiation may be a potential adjuvant treatment that could theoretically be delivered locally by implantable micro-electromechanical systems that sense and kill early recurrence and/or minimally residual cancer. In vitro irradiation experiments are limited because they commonly use a single cell line. Therefore o...

Tumour Treating Fields (TTFs) for recurrent and newly diagnosed glioblastoma multiforme.

In the last decade, significant advances have been made in Glioblastoma Multiforme treatment with the novel use of alternating electrical fields, also termed as tumour treating fields (TTFs). This modality has shown promising results in recurrent and newly diagnosed GBM patients, and according to some, may soon be considered an addition to the previously known 'trifecta' of GBM standard of care, i.e., surgery, chemo and radiation therapy.Here we review the existing data on TTF for both recurrent and newly d...

Good tolerability of maintenance temozolomide in glioblastoma patients after severe hematological toxicity during concomitant radiotherapy and temozolomide treatment: report of two cases.

Glioblastoma is the most common and aggressive primitive brain tumor in adults. Temozolomide (TMZ) administered daily with radiation therapy, followed by adjuvant TMZ has become the standard treatment. Although TMZ treatment has been considered to have a low toxicity profile, studies have noted the development of a severe myelosuppression, especially during the concomitant treatment; this toxicity may in some cases be prolonged and consequently treatment must be definitively discontinued. We analyzed two ca...

The significance of MGMT methylation in Glioblastoma Multiforme prognosis.

Methylation of O6-methylguanine-DNA methyltransferase (MGMT) has been extensively studied as a biomarker in predicting the prognosis of patients with GBM (Glioblastoma multiforme). Its significance has been studied in various subgroups, including age, gender and even race. Correlation between prognosis with MGMT methylation and different treatment regimens has also been studied in detail. There are multiple techniques to analyze MGMT methylation in tumour specimen. We review the current evidence for the imp...

Exosomal Transfer of miR-151a Enhances Chemosensitivity to Temozolomide in Drug-resistant Glioblastoma.

Chemoresistance blunts the effect of Temozolomide (TMZ) in the treatment of glioblastoma multiforme (GBM). Whether exosomal transfer of miRNAs derived from TMZ-resistant GBM cells could confer TMZ resistance remains to be determined. qPCR was used to determine miR-151a expression in two TMZ-resistant GBM cell lines. The direct targets of miR-151a were identified by microarray assays, bioinformatics and further RNA chromatin immunoprecipitation (RNA-ChIP) assay. We characterized exosomes from TMZ-resistant ...

Pyr3 Induces Apoptosis and Inhibits Migration in Human Glioblastoma Cells.

Glioblastoma, also known as glioblastoma multiforme (GBM), is a fast-growing type of tumor that is the most aggressive brain malignancy in adults. According to GEO profile analysis, patients with high transient receptor potential canonical 3 (TRPC3) expression have poor survival rates. The aim of this study is to evaluate the effects of Ethyl-1-(4-(2,3,3-trichloroacrylamide)phenyl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylate (Pyr3), a selective TRPC3 channel blocker, on the proliferation and migration of ...

Thioridazine inhibits autophagy and sensitizes glioblastoma cells to temozolomide.

Glioblastoma multiforme (GBM) has a poor prognosis with an overall survival of 14-15 months following surgery, radiation and chemotherapy using temozolomide (TMZ). A major problem is that the tumors acquire resistance to therapy. In an effort to improve the therapeutic efficacy of TMZ, we performed a genome-wide RNA interference (RNAi) synthetic lethality screen to establish a functional gene signature for TMZ sensitivity in human GBM cells. We then queried the Connectivity Map database to search for drugs ...
