MicroRNA-640 Inhibition Enhances the Chemosensitivity of Human Glioblastoma Cells to Temozolomide by Targeting Bcl2 Modifying Factor
Biochem Genet. 2022 Aug 19. doi: 10.1007/s10528-022-10264-x. Online ahead of print.ABSTRACTGlioblastoma (GBM) is the most malignant and challenging type of astrocytoma and also notoriously acknowledged as the most common primary brain tumor globally. Currently, chemotherapy is the most master therapy for tumor and is essential in clinical treatment for GBM. Nevertheless, the characterization of chemotherapy resistance seriously hinders clinical chemotherapy treatment. Accordingly, there are imperious demands for the exploitation of novel chemosensitizer to promote the efficacy of chemotherapy. Our current study was conduct...

EZH2 as a new therapeutic target in brain tumors: Molecular landscape, therapeutic targeting and future prospects
Biomed Pharmacother. 2021 Dec 11;146:112532. doi: 10.1016/j.biopha.2021.112532. Online ahead of print.ABSTRACTBrain tumors are responsible for high mortality and morbidity worldwide. The brain tumor treatment depends on identification of molecular pathways involved in progression and malignancy. Enhancer of zeste homolog 2 (EZH2) has obtained much attention in recent years in field of cancer therapy due to its aberrant expression and capacity in modulating expression of genes by binding to their promoter and affecting methylation status. The present review focuses on EZH2 signaling in brain tumors including glioma, gliobla...

LY294002 and sorafenib as inhibitors of intracellular survival pathways in the elimination of human glioma cells by programmed cell death
Cell Tissue Res. 2021 Jul 8. doi: 10.1007/s00441-021-03481-0. Online ahead of print.ABSTRACTGliomas are aggressive brain tumors with very high resistance to chemotherapy throughout the overexpression of multiple intracellular survival pathways. Therefore, the aim of the present study was to investigate for the first time the anticancer activity of LY294002, phosphatidylinositol 3-kinase (PI3K) inhibitor and sorafenib, and rapidly accelerated fibrosarcoma kinase (Raf) inhibitor in the elimination of human glioma cells by programmed cell death. MOGGCCM (anaplastic astrocytoma, III) and T98G (glioblastoma multiforme, IV) cell...

TRPM7 Induces Tumorigenesis and Stemness Through Notch Activation in Glioma
In this study, we determined the major contributor(s) to TRPM7 mediated glioma stemness by further deciphering each individual Notch signaling. We first determined whether TRPM7 is an oncotarget in glioblastoma multiforme (GBM) using the Oncomine database. Next, we determined whether TRPM7 silencing by siRNA TRPM7 (siTRPM7) induces cell growth arrest or apoptosis to reduce glioma cell proliferation using cell cycle analysis and annexin V staining assay. We then examined the correlations between the expression of TRPM7 and Notch signaling activity as well as the expression of GSC markers CD133 and ALDH1 in GBM by downregula...

CD164 regulates proliferation, progression, and invasion of human glioblastoma cells.
Authors: Wang CC, Hueng DY, Huang AF, Chen WL, Huang SM, Yi-Hsin Chan J Abstract Grade IV astrocytoma, also known as glioblastoma multiforme (GBM), is the most common and aggressive intracranial glial tumor. GBM is associated with very poor survival and effective treatments have remained elusive so far. Mounting evidence indicates that CD164 contributes to stemness and tumorigenesis in normal cells and is overexpressed in various tumor types, including glioblastoma. Using tissue microarray immunohistochemistry, we show that there is a significant correlation between CD164 expression and glioma type and grade. Deple...

Cell Division Cycle Associated 7 Like Predicts Unfavorable Prognosis and Promotes Invasion in Glioma
ConclusionsCDCA7L is highly expressed in human glioma tissues and a high CDCA7L expression level predicts the dismal prognosis for glioma patients. Moreover, CDCA7L can promote glioma invasion, which can serve as an independent potential prognostic biomarker for glioma patients.

Delivery of Small Interfering RNA to Inhibit Vascular Endothelial Growth Factor in Zebrafish Using Natural Brain Endothelia Cell-Secreted Exosome Nanovesicles for the Treatment of Brain Cancer
In this study, we tested whether brain endothelial cell-derived exosomes could deliver siRNA across the blood –brain barrier (BBB) in zebrafish. Natural exosomes were isolated from brain endothelial bEND.3 cell culture media and vascular endothelial growth factor (VEGF) siRNA was loaded in exosomes with the assistance of a transfection reagent. While fluorescence-activated cell flow cytometry and immunocy tochemistry staining studies indicated that wild-type exosomes significantly increased the uptake of fluorescence-labeled siRNA in the autologous brain endothelial cells, decreased fluorescence intensity was observed in...

STMC-26. MULTIVALENT CATIONIC LIPOSOMES FOR siRNA TRANSFECTION OF PATIENT DERIVED GLIOMA INITIATING CELLS
Glioma initiating cells (GICs) have been implicated as the root cause of treatment failure and tumor recurrence in glioblastoma multiforme (GBM). Therapeutic targeting of GICs is therefore essential to ensure effective treatment without relapse. A novel approach to modulate protein expression in cancer cells is the delivery of siRNAs using liposomes. However, past attempts to transfect cells using neutral liposomes have proven challenging and inefficient owing to the highly refractory nature of these cells. We therefore sought to develop a multivalent cationic liposome (MVCL) formulation for efficient and reproducible...

P08.67 Inhibition of MutT homolog 1 (MTH1) in glioblastoma multiforme results in impaired cell migration and tumor growth
Discussion:These results show that MTH1 might play an essential role in both, malignization of glioma and disease progression in recurrent glioblastoma. Moreover, the MTH1 level in patients seems to influence tumor growth and could be targeted by crizotinib indicating a role for potential future therapies.

Epithelial Cell Transforming 2 and Aurora Kinase B Modulate Formation of Stress Granule-Containing Transcripts from Diverse Cellular Pathways in Astrocytoma Cells.
Abstract Stress granules are small RNA-protein granules that modify the translational landscape during cellular stress to promote survival. The RhoGTPase RhoA is implicated in the formation of RNA stress granules. Our data demonstrate that the cytokinetic proteins epithelial cell transforming 2 and Aurora kinase B (AurkB) are localized to stress granules in human astrocytoma cells. AurkB and its downstream target histone-3 are phosphorylated during arsenite-induced stress. Chemical (AZD1152-HQPA) and siRNA inhibition of AurkB results in fewer and smaller stress granules when analyzed using high-throughput fluoresc...
