Project description:The long noncoding RNA LINC00152 shows ubiquitous expression and is often upregulated in tumor entities compared to healthy tissues. LINC00152 promotes malignant progression in the glioblastoma cell line U87. Here, LINC00152 knockdown leads to a reduction of migration and invasion of tumor cells. However, LINC00152 seems to have an opposite effect in another glioblastoma cell line A172. For this reason, the transcriptional patterns after LINC00152 knockdown in both cell lines (U87 and A172) were compared to identify the differences.
Project description:Early passages (< 10) of frequently used GBM cell lines A172, LN18, LN229, T98G, U87-MG, U138-MG and U251-MG were characterised for genomic copy number by array CGH.

Project description:To investigate the target genes of HOTAIRM1 in glioma cells, we conducted a lncRNA + mRNA expression microarray analysis to identify novel HOTAIRM1 regulating genes. Three glioma cell lines U87MG, T98G and A172 stably knockdown HOTAIRM1 were used as the experiments models. We conservatively established a minimum of 2-fold difference between shHOTAIRM1 (knockdown HOTAIRM1) and shNT (control group), and identified 10 up-regulated and 22 down-regulated genes that met the threshold in all cell lines.
Project description:We have employed whole RNA microarray expression profiling as a discovery platform to identify genes regulated by overexpression of miR-145 in U87 glioma cell. Lentivirus containing miR-145 coding sequence was infected to U87 cell to make U87 overexpressing miR-145. We did genome microarray between U87 and U87 overexpressing miR-145.
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.
Project description:We have employed whole RNA microarray expression profiling as a discovery platform to identify genes regulated by overexpression of miR-145 in U87 glioma cell. Lentivirus containing miR-145 coding sequence was infected to U87 cell to make U87 overexpressing miR-145. We did genome microarray between U87 and U87 overexpressing miR-145. Total RNAs from U87 cell or U87 overexpressing miR-145 were extracted. Whole RNA microarray expression profiling was performed between them.
