Differential gene expression profiles between SUM149 cells transfected with control siRNA and SUM149 cells transfected with siRNA targeting tarzarotene-induced gene 1 (TIG1)

ABSTRACT: We identified tazarotene-induced gene 1 (TIG1) as a potential tumorigenic gene in IBC. To investigate the underlying mechanism by which TIG1 promotes tumor growth and invasiveness of IBC cells, we first sought to identify TIG1 functional partners by using DNA microarray analysis to compare gene expression profiles between SUM149 cells transfected with control siRNA and SUM149 cells transfected with siRNA targeting TIG1. We identified receptor tyrosine kinase Axl as a functional partner of TIG1.

Differential gene expression profiles between SUM149 cells transfected with control siRNA and SUM149 cells transfected with siRNA targeting tarzarotene-induced gene 1 (TIG1)

Project description:We identified tazarotene-induced gene 1 (TIG1) as a potential tumorigenic gene in IBC. To investigate the underlying mechanism by which TIG1 promotes tumor growth and invasiveness of IBC cells, we first sought to identify TIG1 functional partners by using DNA microarray analysis to compare gene expression profiles between SUM149 cells transfected with control siRNA and SUM149 cells transfected with siRNA targeting TIG1. We identified receptor tyrosine kinase Axl as a functional partner of TIG1. SUM149 cells transiently transfected with control siRNA or siRNA targeting TIG1 were used. Total RNA was extracted and purified using RNeasy mini kit (Qiagen, Inc.) according to the manufacturer’s instructions. The integrity of the obtained RNA was assessed using an Agilent 2100 BioAnalyzer (Agilent Technologies). The Affymetrix HGU133 plus platform was used for hybridization, staining, and imaging of the arrays by following the manufacturer’s instructions. Gene expression analysis was performed in triplicate.

Transcriptomic analysis of A3250 inflammatory breast cancer (IBC) cells, SUM149 IBC and MDA-MB-231 non-IBC cells

Project description:Purpose: Transcriptome profiling (RNA-seq) of a novel human Inflammatory Breast Cancer cell line A3250 in comparison to SUM149 and MDA-MB-231 Inflammatory Breast Cancer (IBC) is the most aggressive form of breast cancer with distinct clinical and histopathological features, but understanding of the unique aspects of IBC biology lags far behind that of other breast cancers. We describe a novel triple-negative IBC cell line, A3250, that recapitulates key features of human IBC in a mouse xenograft model.The purpose of this study was to compare differences in gene expression between A3250 IBC, MDA-MB-231 non-IBC and SUM149 IBC that does not present with typical clinical sympotms of IBC in a mouse model, with the goal of identifying unique molecular features for this unique type of breast cancer Results: RNA-Seq analysis identified expression profile characteristic for the novel A3250 IBC cell line, compared to SUM149 IBC and MDA-MB-231 non-IBC.

Expression data from SUM149 inflammatory breast cancer cells cultured in monolayer or Matrigel

Project description:Inflammatory breast cancer (IBC) is a rare type of breast cancer but accounts for up to 10% of breast cancer-related deaths. Plasticity between epithelial and mesenchymal feature is reported to be crucial in metastasis of IBC. Using Matigel culture, we induced epithelial to mesenchymal transition (EMT) in epithelial-like SUM149 IBC cells and identified overexpressed genes in this EMT process.

RNA-sequencing of treatment-naive, Lapatinib-resistant, and resistant-reversal SUM149 IBC cells

Project description:In this experiment, SUM149 IBC cells were cultured using baseline medium (N=3), and in baseline medium supplemented with increasing concentration of Lapatinib to induce resistance (N=3; rSUM149). Resistant reversal SUM149 cells (rrSUM149) were then generated by culturing in rSUM149 cells in baseline medium. Gene expression data were generated to identify differentially expressed genes, as well as differentially activated proteins and pathways during Lapatinib resistance and resistance reversal. Gene expression were also integrated with proteome expression data generated under the same conditions.

Expression data from SHP specific siRNA or nonspecefic siRNA transfected rat astrocytes

Project description:To clarify the effect of SHP in LXRs-mediated signaling pathway, we performed global gene expression analysis of SHP siRNA transfected- or control siRNA transfected- astrocytes after IFN-γ and LXRs agonist. Microarray analysis revealed that expression of several genes encoding inflammatory mediators were reversed in SHP siRNA transfected-astrocytes, when compared with control siRNA transfected-astrocytes.

RNA sequencing facilitates quantitative analysis of siRNA circHIPK2 transfected neural stem cells and siRNA circCon transfected neural stem cells transcriptomes

Project description:We report the application of Illumina paired-end RNA-seq approach for transcriptome of siRNA circHIPK2 transfected neural stem cells and siRNA circCon transfected neural stem cells . By removing sequence-dependent bias and amplification noise using UMI-tools. The mapped reads of each sample were assembled using StringTie. After the final transcriptome was generated, StringTie and edgeR was used to estimate the expression levels of all transcripts. By obtaining a total of million paired-end reads of sequence from neural stem cells , we generated transcriptome profiles of siRNA circHIPK2 transfected neural stem cells and siRNA circCon transfected neural stem cells , respectively. We found 201 differentially expressed genes (DEGs) between siRNA circHIPK2 transfected neural stem cells and siRNA circCon transfected neural stem cells. This study provides a detailed analysis of the underlying mechanisms of stroke，such as neuronal injury and long-term effect, generated by RNA-seq technology.
