Transcriptome analysis of ABCB7 overexpressed U87MG glioblastoma cells

ABSTRACT: This study investigated the biological function of ABCB7 in U87MG glioblastoma cell line. Many ABC transporters are known contributions to drug resistance and various biological process. However, mitochondrial ABC transporters aren’t known mechanism to control biological process. We identified the potential roles of ATP-binding cassette (ABC) transporter subfamily member 7 (ABCB7), one of the mitochondrial ABC transporters. ABCB7 activates signaling pathway of hypoxia-inducible factor 1 alpha (HIF1α) by hypoxia independent regulation. This signaling pathway regulates the death inhibitory genes and survival related genes. Also, ABCB7 downregulates cell cycle related genes. Our results provide that ABCB7 is essential for the survival of malignant brain tumors.

Expression data from U87MG subclones

Project description:U87MG is a glioblastoma cell line that shows substantial heterogeneity despite long-term passaging. We used microarrays to identify variations in gene expression that are associated with phenotypic differences among subclones derived from U87MG.

Differential gene expression analysis of U87MG EGFRvA cells vs. U87MG EGFR cells

Project description:EGFRvA is a novel and widely-expressed EGFR isoform, whose upregulation is positively related to glioma grades. Intriguingly, it is the upregulation of EGFRvA but not EGFR that significantly correlates with a poor prognosis in glioma patients. Cancer cells expressing EGFRvA (relative to EGFR) display a higher invasive capacity and a lower sensitivity to EGFR tyrosine kinase inhibitors (TKIs). To investigate the significant differently expressed genes between U87MG EGFRvA cells and U87MG EGFR cells，microarray experiments were conducted.

Transcriptome analysis of CD133 overexpressed U87MG glioblastoma cells

Project description:This study investigated the biological function of CD133 by ectopic expression of CD133 in U87MG cell line. Although CD133 is widely used as a cancer stem cell marker, there are a few studies that examined its own biological functions. While a number of loss-of-function studies about CD133 have shown that CD133 have effects on cancer progression, there are few gain-of-function studies about functions of CD133. Thus, we identified the potential function of CD133 by its overexpression in U87MG glioblastoma cell line. Though there were no significant changes in cell growth and sphere forming ability, elevated IL-1β and its downstream chemokines (CCL3, CXCL3, CXCL5) may function as chemoattractants which affect recruitment of Ly6G+ neutrophils surrounding necrotic regions in vivo and migration of neutrophil-like dHL-60 cells. Taken together, this results imply that CD133 can regulate IL-1β signaling, and promotes the environmental change.

Differential gene expression analysis between adherent U87MG cells and U87MG cell-derived glioma stem-like cells (P4E8 cells).

Project description:We established tumorspheres from human glioblastoma U87MG cells by single cell-derived tumorsphere formation. Among these tumorspheres, P4E8 clone showed cancer stem cell like properties such as self-renewal capacity, expression of cancer stem cell markers, resistance to anti-cancer agents and in vivo tumorigenicity. To find novel therapeutic target molecules, we performed differential gene expression analysis between U87MG and P4E8 cells.

Next Generation Sequencing Facilitates Quantitative Analysis of U87MG Cell Transcriptomes

Project description:Next-generation sequencing (NGS) has significantly advanced the elucidation of developmental signaling mechanisms that are important for U87MG cells under differente treatment. We report here the application of RNA-sequencing technology for transcriptome profile of U87MG cells treated with CAR neutrophils, nanodrugs, and CAR neutrophils loaded nanodrugs. Six U87MG samples were performed in IIIumina HiSeq2500. The resulting sequence reads were mapped to human genome (hg19) using HISAT, and the RefSeq transcript levels (RPKMs) were quantified using the python script rpkmforgenes.py. Our RNA-seq data analyzed different cellular signal pathways under treatment. This study shows a detailed analysis of U87MG transcriptomes generated by RNA-seq technology, providing insight into the mechanisms underlying CAR neutrophils lysis the tumor cells.
