ZBTB18 is a repressor of mesenchymal genes in Glioblastoma [JX6]

Project description:The transcriptional repressor ZBTB18 was overexpressed in the brain tumor xenoline JX6 by lentiviral transduction. Three independent transduction were performed (biological replicates) and analyzed by gene expression aray. Gene set enrichemnt analysis (GSEA) showed changes in the expression of mesenchymal signature. A subset of genes was further valiadted by qPCR. These results indicate a role of ZBTB18 as repressor of mesenchymal genes in Glioblastoma.

ZBTB18 is a repressor of mesenchymal genes in Glioblastoma [BTSC233]

Project description:The transcriptional repressor ZBTB18 was overexpressed in the brain tumor stem cell-like BTSC233 by lentiviral transduction. Three independent transduction were performed (biological replicates) and analyzed by gene expression aray. Gene set enrichemnt analysis (GSEA) showed changes in the expression of mesenchymal signature. A subset of genes was further valiadted by qPCR. These results indicate a role of ZBTB18 as repressor of mesenchymal genes in Glioblastoma.

Analysis of gene expression changes upon ZBTB18 full length (FL), ZBTB18 full length-mutant (FL-mut), ZBTB18 short form Nte (SF-Nte) and ZBTB18 short form Nte (SF-mut) in SNB19 glioblastoma cell line

Project description:ZBTB18 is a transcriptional repressor and tumor suppressor in glioblastoma (GBM). Specifically, it acts as a repressor of mesenchymal genes. ZBTB18 interacts with C-terminal binding proteins 1 and 2 through a VLDL motif. In GBM, ZBTB18 is cleaved the the calpain 2 intracellular proteases which generates truncated Nte and Cte short forms. Here we have investigated gene expression changes which occur upon the expression of ZBTB18 full lenght or ZBTB18 short form Nte (SF-Nte), as well as upon expression of the mutated counterparts which no longer interacts with CTBP1/2.

Genome wide mapping of binding sites of ZBTB18 and CTBP2 in glioblastoma cancer cells

Project description:CTBP2 is a transcriptional co-repressor/co-activator palying a role in EMT. We have identified CTBP2 as a protein interacting with ZBTB18, a transcriptional repressor and tumor suppressor in GBM. Here, we have performed genome wide mapping of CTBP2 and ZBTB18 binding sites in GBM to characterized their gene regulation mechanism.

Core fucosylation in mesenchymal glioblastoma

Project description:Glycoproteomic screening indicates that core fucosylation activation is more highly enhancedin mesenchymal (MES) than in proneural (PN) glioblastoma cancer stem cells (GSCs) and this pattern is retained in subgroup-specific xenograftsand human patients’ samples. Most MES-restricted core fucosylated proteins are involved in therapeutically relevant pathological processes, such as extracellular matrix interaction and tumor invasion.

Divergent transcriptomic signatures from putative mesenchymal stimuli in glioblastoma cells

Project description:In glioblastoma, a mesenchymal phenotype is associated with especially poor patient outcomes. Various glioblastoma microenvironmental factors and therapeutic interventions are purported drivers of the mesenchymal transition, but the degree to which these cues promote the same mesenchymal transitions and the uniformity of those transitions, as defined by molecular subtyping systems, is unknown. Here, we investigate this question by analyzing publicly available patient data, surveying commonly measured transcripts for mesenchymal transitions in glioma-initiating cells (GIC), and performing next-generation RNA sequencing of GICs. Analysis of patient tumor data reveals that TGFβ, TNFα, and hypoxia signaling correlate with the mesenchymal subtype more than the proneural subtype. In cultured GICs, the microenvironment-relevant growth factors TGFβ and TNFα and the chemotherapeutic temozolomide promote expression of commonly measured mesenchymal transcripts. However, next-generation RNA sequencing reveals that growth factors and temozolomide broadly promote expression of both mesenchymal and proneural transcripts, in some cases with equal frequency. These results suggest that glioblastoma mesenchymal transitions do not occur as distinctly as in epithelial-derived cancers, at least as determined using common subtyping ontologies and measuring response to growth factors or chemotherapeutics. Further understanding of these issues may identify improved methods for pharmacologically targeting the mesenchymal phenotype in glioblastoma.

GPR56/ADGRG1 inhibits Mesenchymal Differentiation and Radioresistance in Glioblastoma [GIC7]

Project description:A mesenchymal transition occurs both during natural evolution of glioblastoma (GBM) and in response to therapy. However, the molecular mechanisms underlying mesenchymal differentiation are not well understood. We have found that the adhesion G protein-coupled receptor GPR56/ADGRG1 inhibits mesenchymal differentiation and radioresistance in glioblastoma stem-like initiating cells (GICs). Here, we have performed microarray analysis of parental- versus GPR56 knockout-GICs to identify gene expression changes upon GPR56 knockout

GPR56/ADGRG1 inhibits Mesenchymal Differentiation and Radioresistance in Glioblastoma

Project description:A mesenchymal transition occurs both during natural evolution of glioblastoma (GBM) and in response to therapy. However, the molecular mechanisms underlying mesenchymal differentiation are not well understood. We have found that the adhesion G protein-coupled receptor, GPR56/ADGRG1, inhibits mesenchymal differentiation and radioresistance in glioblastoma stem-like initiating cells (GICs). Here, we have performed microarray analysis of control- versus GPR56 knockdown-GICs to characterize gene expression changes upon GPR56 knockdown and identify a gene expression signature associated to GPR56.
