Trancriptome profiling of glioma cell line U87 and U251 with LAMP2A knockdown

Project description:The objective of the study was to examine the gene expression changes in glioma cell line U87 and U251 with LAMP2A knockdown. There were 15 samples in total- U87-1, U87-2, U87-3, U87-1812-1, U87-1812-2, U87-1812-3, U251-1, U251-2, U251-3, U251-1812-1, U251-1812-2, U251-1812-3, U251-1813-1, U251-1813-2, and U251-1813-3. U87-1 to U87-3 and U251--1 to U251-3 were used as the control groups (CON). U87-1812-1 to U871812-3, U251-1812-1 to U251-1812-3, and U251-1813-1 to U251-1813-3 were used as the experimental groups (shLAMP2A-1 and shLAMP2A-2). The total RNA of each sample was extracted from the stable transfected glioma cells by using TRIzol reagent. Then the RNA samples were processed for high throughput transcriptome sequencing on Illumina HiSeq 3000 platform. There were two types of libraries: the circRNA, mRNA, and lncRNA were all constructed by removing rRNA (one library, three types of RNA were analyzed together), and the insert fragment was about 300bp; the small RNA was constructed and analyzed separately, mainly microRNA of about 22bp. Results: among 60612 cleaned mRNAs, 781 were differentially expressed in U87-1812 group compared with U87 group, 146 were differentially expressed in U251-1812 group compared with U251 group, 43 were differentially expressed in U251-1813 group compared with U251 group (padj ≤ 0.05 and expression change ≥2 fold). The differential expressed genes distributed in all chromosomes. Functional annotation with GO and KEGG enrichment revealed the top functional groups including inflammation, DNA replication, cell adhesion, TNF, IL17, and axon guidance signaling pathways.

Expression data from U87 glioma cells and U87-2M1 glioma cells

Project description:An experimental lung metastasis assay was used to derive an invasive subline of U87 that is metastatic in mice. We used microarray analyses to find out over-represented gene ontologies that can explain the observed enhanced invasiveness of U87-2M1 cells. Early passage U87-2M1 cells and parental U87 glioma cells from ATCC were selected for RNA extraction and hybridization on microarray

FAT1 knockdown in immortalized astrocyte and glioma cell lines

Project description:The FAT1 gene was knocked down using 2 independent siRNAs, in immortalized human astrocytes and U87 and U251 glioma cell lines. A non-targeted scramble siRNA was used as a control. Scramble, FAT1 siRNA#1 and FAT1 siRNA#2 were transfected into each cell line, in duplicate, and RNA analyzed using the Affymetrix U133A 2.0 platform.

Microarray analysis of U87 glioma cells after transient knockdown of FOXM1

Project description:FOXM1 plays a key role in M phase in normal cells and is overexpressed in human glioma. We found that FOXM1 deprivation could sensitize the glioma cells to TMZ chemotherapy. To find out the mechanistic regulation of FOXM1 in chemo-resistant genes, we used microarrays to select the potential genes regulated by FOXM1 which dominates in glioma chemo-resistance. U87 glioma cells were transiently transfected with none-target siRNA or FOXM1 siRNA. Total RNA were extracted after 48 hours and subjected to the microarray.

mRNA sequence of the glioma cell line U251 after TEAD3 knockdown

Project description:Glioma is a malignant primary tumour that occurs in the central nervous system. TEA domain transcription factor (TEAD) family proteins are the Hippo pathway's ultimate effector molecules. The function of TEAD3 in gliomas is still unclear. Therefore, RNA sequencing was performed on TEAD3 knockdown U251 cells and normal U251 cells. The samples in this study included normal U251 control group and TEAD3 knockdown group. Each group contained three samples. Total RNA was extracted using Trizol reagent following the manufacturer's procedure. The total RNA quantity and purity were analysis of Bioanalyzer 2100 and RNA 6000 Nano LabChip Kit, high-quality RNA samples with RIN number > 7.0 were used to construct sequencing library. Gene Set Enrichment Analysis (GSEA) based on the sequencing results showed that knockdown of TEAD3 in the U251 cell line caused changes in several important pathways, including CTLA4 inhibitory pathway, defective pyroptosis, signaling by Hippo, regulation of TP53 activity, E2F mediated regulation of DNA replication, and FCGR3A mediated phagocytosis.

miR-139-5p induced gene expression alteration in glioma cells

Project description:To evaluate gene expression alteration following miR-139-5p transfection in glioma cells. We find a significant downregulation of two transcriptional factors, E2F3 and HoxA9. Total RNA were extracted from U87, LN229 and U251 glioma cells transfected with miR-139-5p or miRNA negative control.

Development of microRNA (miRNA) expression signatures for human glioma-initiating cells (GICs)

Project description:To identify a novel miRNA that is aberrantly expressed in GICs, we analyzed differences in miRNA expression between the human GICs and glioma cell lines and neural stem cells by miRNA microarrays. We examined the miRNA expression profiles of five human GICs that were obtained from human glioma samples and two human glioma cell lines, U87 and U251, and NSC (neural stem cells) as a control.
