Transcriptomic profiling of Ewing's sarcoma cell lines after knockdown of TRIP6

ABSTRACT: This study aimed to explore the role of the Zyxin-related protein TRIP6 (thyroid receptor interacting protein 6) in Ewing's sarcoma (ES). By interrogation of published miccroarray data, we observed that of all seven Zyxin-proteins only TRIP6 is highly overexpressed in ES compared to normal tissues. RNA interference experiments and subsequent microarray and gene-set enrichment analyses indicated that TRIP6 expression is associated wth a pro-proliferative and pro-invasive transcriptional signature. Consistently, functional assays demonstrated that TRIP6 promotes migration, invasion, long-term proliferation and clonogencity of ES cells. A673 and SK-N-MC Ewing sarcoma cells were transfected with specific siRNA against TRIP6 (siTRIP6_4 or siTRIP6_5) or negative control siRNA (siControl) or Mock-transfected.

Identification of potential miR-31 target-genes in Ewing Sarcoma

Project description:We identified miR-31 as strongest downregulated miRNA in the bone tumor Ewing sarcoma. To identify miR-31 targets in ES genome-wide gene expression profiles of TC71 cells transfected with miR-31 mimics or negative control (Life Technologies) generated in three independent experiments (a, b, c). Total RNA was isolated from cells after 72 h incubation in serum-reduced medium (1% FCS) and three transfections. Fifteen upregulated and 14 downregulated genes were detected with a 2 fold change cut-off (FDR <0.05).

Expression Data from siRae1 and siNT infected with VSV or mock infected

Project description:To test the effect of silencing Rae1 on expression on RNA polymerase II transcripts, host mRNAs were analysed by cDNA microarrays. We hypothesized that if silencing Rae1 expression increases cellular resistance to inhibition of transcription in VSV infected cells, mRNA characteristic of host antiviral response would be increased than compared to cells transfected with control siRNA. HeLa cells transfected with siRNA targeted against Rae1 (siRae1) or against non-targeting siRNA (siNT). The sequence of nontargeting (NT) siRNA is scrambled and does not match any sequence on the human genome. Transfected cells were either infected with VSV or mock infected. Six hours later RNA was extracted from the cells. Two separate experiments of such were analyzed by microarrays

Knockdown of KSHV viral interferon-regulatory factor 3 (vIRF-3) in primary effusion lymphoma (PEL) cells by RNA-Interference

Project description:KaposiM-bM-^@M-^Ys sarcoma-associated hepesvirus (KSHV) encodes four genes with homology to human interferon regulatory factors (IRFs). One of these IRFs, the viral interferon regulatory factor 3 (vIRF-3) is expressed in latently infected PEL cells and required for their continuous proliferation. Moreover, vIRF-3 is known to be involved in modulation of the type I interferon response. In order to identify cellular genes regulated by vIRF-3, cells from the PEL cell line BC-3 (KSHV positive) were transfected with either siRNAs targeted at vIRF-3 (si463 or si716s) or a negative control siRNA without homology to a known gene (siN, siNs). A total of 4 samples were analyzed. This includes two samples with silencing of vIRF-3 expression via RNA-interference (si463 or si716s) and two samples transfected with a negative-control siRNA (siN, siNs). Expression of vIRF-3 was reduced by approximately 75% as estimated by Western blot analysis.

Expression profiling of the TC32 Ewing sarcoma cell line following silencing of SUPT6H, SF3B1 or HNRNPH1

Project description:The investigation of the function of SUPT6H, SF3B1 and HNRNPH1 in Ewing sarcoma The expression profiles of TC32 Ewing sarcoma cells were determine 48 hours post siRNA-transfected. Groups consisted of untreated cells (three samples), and negative control (siNeg) transfected-TC32 cells (six samples), and TC32 cells in which either SUPT6H, SF3B1 or HNRNPH1 were silenced; three different siRNAs corresponding to each gene were assessed separately.

Gene expression profiling of human Ewing sarcoma cells after knockdown of EGR2 or EWSR1-FLI1.

Project description:To get insight in the functional role of EGR2 for Ewing sarcoma, we performed a transcriptional profiling of Ewing sarcoma cells after knockdown of EGR2 and compared the resulting transcriptional signature with that of EWSR1-FLI1-silenced Ewing sarcoma cells. In accordance with the strong EGR2-induction by EWSR1-FLI1, both genes highly significantly overlap in their transcriptional signatures. Gene-set enrichment analyses (GSEA) and DAVID (Database for Annotation, Visualisation and Integrated Discovery) gene ontology analyses indicated a strong impact of EGR2 on cholesterol and lipid biosynthesis resembling its function in orchestrating lipid metabolism of myelinating Schwann cells. A673 and SK-N-MC Ewing sarcoma cells were transfected with specific siRNAs directed against EGR2 or EWSR1-FLI1 or non-targeting control siRNA. 48 h thereafter RNA was harvested and processed for microarray analysis.

Gene expression in human endometrial cancer tissues and serous papillary endometrial cancer cell line, SPAC-1L, treated by STAT1-siRNA and/or IFN-gamma

Project description:Endometrial cancer is one of the most common gynecologic malignancies, and patients with high grade disease, especially serous papillary subtype (SPEC) are often related to the poor outcomes. Recent genome-wide analyses have revealed that SPEC exhibits gene expression profiles that are distinct from the endometrioid histologic subtype; therefore, it is important to identify the SPEC driver genes or pathways responsible for the inherently aggressive phenotypes and to develop SPEC-specific therapies to target these driver genes or pathways. Through array-based analysis and immunohistochemical staining of human endometrial cancer tissue, STAT1 is identified high expressed, and can distinguish SPEC from other subtypes of endometrial cancer. In vitro and in vivo experiments show STAT1 role as a pro-survival factor in SPEC. STAT1 was identified as a master gene modulating “transcriptional pro-survival pathways” to enhance multiple malignant characteristics These finding may suggest that targeting of STAT1, the SPEC driver gene, may provide the means to improve poor outcomes for patients with SPEC. We used microarrays to clarify the changes of gene expression along with STAT1-siRNA treatment and to confirm whether there are any changes on genes expression related to STAT1 pathway. We also used the microarray data to clarify genes signatures which can distinguish subtype of human endometrial cancers.
