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 Inflammatory breast cancer (IBC) cells

Project description:ERβ expression is associated with less metastasis in patients with IBC tumors. We investigated this association in preclinical models of IBC by knocking out ERβ in cells. Ablation of ERβ promotes migration and invasion of IBC cells and increases the metastatic potential of IBC tumors in vivo. We used microarrays to detail the global programme of gene expression underlying the increased migration of ERβ knockout cells and identified distinct classes of up-regulated genes during this process.

FC-IBC-02: A New in vitro-in vivo Model of Triple Negative Inflammatory Breast Cancer

Project description:Inflammatory breast cancer (IBC) is the most aggressive type of advanced breast cancer and is associated with a poor prognosis. We have developed a new model of IBC derivated from the pleural effusion of a 49-year-old woman with metastatic secondary IBC. FC-IBC02 tumor cells were isolated from the pleural effusion and cultured under non-adherent conditions, resulting in the formation of spheroids or mammospheres. FC-IBC02 are triple negative (estrogen receptor negative, progesterone receptor negative and ErbB2 negative) and strongly positive for E-cadherin, beta-catenin and vimentin. FC-IBC02 cells developed breast tumors when they were injected into the mammary fat pad of SCID mice and characteristic tumor emboli were detected. Breast tumor xenografts were poorly differentiated triple negative carcinomas and all injected mice developed metastasis in the lungs and lymph nodes. These IBC tumor cells showed genomic alterations in all chromosomes, with the gains/amplifications more common than the deletions/losses. Duplicated regions were on 1q, 2p, 3q, 8q and 18p and chromosomes 7 and 9. The 8q chromosome arm where the MYC oncogene resides was amplified up to seven fold. Chromothripsis (local chromosome shattering) was observed on chromosome 11q and losses were found on 8p, 11q, 16q and 17p (location of TP53). FC-IBC-02 cells expressed the stem cell marker CD44, EpCAM and strongly expressed EGFR and ALK. In summary, this novel preclinical model demonstrated that IBC is a disease enriched for highly tumorigenic cells which harbor a stem cell phenotype. This IBC model is ideal for the study of the metastatic process and to evaluate targeting therapeutic modalities. Total RNA were isolated from IBC-02, IBC-02 in mammosphere growth, IBC3, SUM149, SUM190, MDA-MB231, and MDA-MB468 cell lines. Affymetrix Human U133 Plus 2.0 arrays were used for whole-genome gene expression assays. Duplicate samples were analyzed for each cell line.
