Glioblastoma (GBM) is the most prevalent malignant primary brain tumor with a very poor survival rate. Temozolomide (TMZ) is the common chemotherapeutic agent used for GBM treatment. We recently demonstrated that simvastatin (Simva) increases TMZ-induced apoptosis via the inhibition of autophagic flux in GBM cells. Considering the role of the unfolded protein response (UPR) pathway in the regulation of autophagy, we investigated the involvement of UPR in Simva–TMZ-induced cell death by utilizing highly selective IRE1 RNase activity inhibitor MKC8866, PERK inhibitor GSK-2606414 (PERKi), and eIF

Among central nervous system tumors, glioblastoma (GBM) is the most common and the most malignant type. Even under current standard treatments, the overall survival rate is still low and the recurrence rate is high. Therefore, developing novel and effective therapy is urgently needed. CC12, a synthesized small molecule, was evaluated for the potential anti-GBM effects in two GBM cell lines, U87MG and U118MG. The observations of cell morphology, MTT assay, flow cytometry-based apoptosis after CC12 treatment, were conducted. Western blot was performed for the investigation of the apoptotic mecha

OBJECTIVES/GOALS: Glioblastoma (GBM) is the most malignant brain tumor in adults and remains incurable with an average survival of 15 months after diagnosis. There is great need for treatment options without side effects that are devastating to the quality of life for patients. GBM tumors can circumvent cellular damage by upregulating antioxidant production. METHODS/STUDY POPULATION: Highly aggressive tumors tend to exhibit increased oxidative metabolism, and thus rely on a mechanism to eliminate reactive oxygen species (ROS) in order for cells to evade autophagy and cell death.

Glioblastoma multiforme (GBM) is the most aggressive malignant brain tumor known with a poor survival rate despite current advances in the field of cancer. Additional research into the pathophysiology of GBM is urgently needed given the devastating nature of this disease. Recent studies have revealed the unique cellular physiology of GBM cells as compared with healthy astrocytes. Intriguingly, GBM cells are incapable of de novo cholesterol synthesis via the mevalonate pathway. Thus, the survival of GBM cells depends on cholesterol uptake via low-density lipoprotein receptors (LDLRs) in the for

Glioblastoma multiforme (GBM) is a rapidly progressive and deadly form of brain tumor with a median survival rate of ~15 months. GBMs are hard to treat and significantly affect the patient’s physical and cognitive abilities and quality of life. Temozolomide (TMZ)—an alkylating agent that causes DNA damage—is the only chemotherapy choice for the treatment of GBM. However, TMZ also induces autophagy and causes tumor cell resistance and thus fails to improve the survival rate among patients.

Abstract Glioblastoma (GBM) is the most lethal primary brain tumor, with a 5 year survival rate of only 5%. The standard of care for GBM is maximal surgical resection of the tumor, followed by irradiation and chemotherapy. Despite treatment, tumors recur in almost 100% of patients. There are subpopulations of cells in GBM that are radioresistant and chemoresistant, and new treatments will need to inclusively target these cells. KIF11 is a mitotic protein that drives bipolar spindle formation and is crucial for successful completion of mitosis. We previously reported that KIF11 is overexpressed

Despite the aggressive standard of care treatment combining surgical resection, chemo-, and radio-therapy, the median overall survival (OS) is only ~15-18 months. Progressively increasing subject age is inversely associated with GBM patient OS such that older adults tend to have significantly worse survival outcomes compared to younger counterparts.

Abstract Glioblastoma (GBM) is an aggressive form of brain cancer that affects over 12, 000 people each year in the United States. Current treatments such as surgery, chemotherapy, and radiation have limitations and can often fail to achieve full tumor remission, as the five-year survival rate for this disease is around 7%. Recent research has revealed miRNA (miR), small non-coding RNAs that regulate gene expression, as contributors to the suppression and progression of various cancers, including GBM. Exosomes, tiny vesicles released by cells, show great promise as a cancer therapeutic. Our re

Abstract Diffuse midline glioma (DMG), a highly aggressive pediatric brain cancer, and glioblastoma multiforme (GBM), an intractable disease, pose significant clinical challenges. DMG is characterized by a dishearteningly short median survival period of 15 months, and GBM by a low five-year survival rate of merely 6.9 percent. A critical player in these malignancies is Enhancer of zeste homologue 2 (EZH2), a subunit of the polycomb repressive complex 2 (PRC2) that catalyzes histone 3 Lysine 27 tri-methylation (H3K27Me3).

Abstract Immortality is a fundamental hallmark of human cancer cells and therapeutic reversal is of great interest. Telomerase Reverse Transcriptase promoter (TERTp) mutations reactivate TERT expression, the rate limiting step in telomerase activity and cellular immortality. TERTp mutations are the most common non-coding mutation across all cancer types, including glioblastoma (GBM), oligodendroglioma, medulloblastoma, and high-grade meningioma. While prior telomerase therapies lack tumor selectivity and are poorly tolerated, TERTp mutations and their regulation offer a unique opportunity for

Glioblastoma (GBM) is the most popular primary central nervous system cancer and has an extremely expansive course. Aggressive tumor growth correlates with short median overall survival (OS) oscillating between 14 and 17 months. The survival rate of patients in a three-year follow up oscillates around 10%. The interaction of the proteins programmed death-1 (PD-1) and programmed cell death ligand (PD-L1) creates an immunoregulatory axis promoting invasion of glioblastoma multiforme cells in the brain tissue. The PD-1 pathway maintains immunological homeostasis and protects against autoimmunity.

Abstract Resource limitations shape the outcome of competitions between heterogeneous pre-malignant cells. One example of such heterogeneity is in the ploidy (DNA content) of pre-malignant cells. High-ploidy cells need more resources, to synthesize increasing amounts of DNA, RNA and proteins. To model how subpopulations with variable DNA-content compete in the resource limited environment of the human brain we developed a stochastic state-space model of the brain (S3MB). The model discretizes the brain into voxels, whereby the state of each voxel is defined by 8+ variables that are updated ove

A dose of 5x108 CART-EGFRvIII cells was safe, and the cells were able to expand in the host and reach the GBM tumor in the brain.
