ABSTRACT: Transcription profiling by array of MCF-10A cells after retroviral infection with either vector control or prostate-derived ETS factor (PDEF)
Project description:Human EMT PCR array Real-time quantitative PCR analysis of human EMT genes in PCR array data for expression of EMT genes in MCF-7 cells, upon treatment with exosomes released from TSP5-overexpressing human primary adipocytes (ND; ABM-007), compared to exosomes released from matched control adipocytes transduced with control lentiviral vector [Data S5] PCR array data for expression of EMT genes in MCF-7 cells after treating with TSP5 overexpressing cells' exosomes
Project description:Profiling of MCF-7 cell lines stably overexpressing constitutively active Raf-1, constitutively active MEK, constitutively active c-erbB-2, or ligand-activatable EGFR as models of overexpressed growth factor signaling, as well as control vector transfected cells (coMCF-7) and control vector transfected cells long-term adapted for estrogen-independent growth (coMCF-7/lt-E2). Keywords: Cell Line Comparison
Project description:Recent studies suggest that PDEF is required for secretory cell differentiation in several epithelial tissues. To investigate PDEF in the mammary gland, we examined the effect of this transcription factor on gene expression using microarray based profiling of MCF-10A cells. These cells are non-transformed mammary epithelial cells that express protein and gene expression programs of basal epithelial cells and undetectable levels of endogenous PDEF. Bioinformatics analysis of the genes induced or repressed by PDEF overexpression in MCF10A cells revealed a striking effect on expression of luminal and myoepithelial cell markers. Six samples were harvested 26 hours after retroviral infection with either vector control or PDEF. Each condition was performed in triplicate.
Project description:Pokmeon is an oncogenic transcription factor involved in cell growth, differentiation, and oncogenesis,but its regulatory network in breast cancer cells remians elusive . We used microarray to determine the down stream target genes of pokemon by using the MCF-7 cell line with stable ectopic expression of pokemon. The MCF-7 cell clones with high ectopic expression of pokemon were screened by the Hygromycin B,and the control cell line was also obtained by introducing empty vector .Both the RNA were extracted and hybridized with 22k cDNA spots from CapitalBio, Chin
Project description:Zinc finger protein 32 (ZNF32), is regarded as a transcription factor that regulates gene transcription. But the function of ZNF32 in breast cancer metastasis remains unknown. Here, the MCF-7 was transfected with the pENTER-ZNF32 or empty vector to search the target genes with ChIP-seq.
Project description:Genome wide gene expression profiling of response to synthetic progestin ORG2058 in AB32 cells, a PR positive clone of the MCF-10A cell line, was determined after lentiviral transduction with an expression construct encoding human FOXA1. Cells were treated for 6h or 24h with 10nM ORG2058 or vehicle, 48h after transduction with the FOXA1 construct or empty vector control. Gene expression was measured in total RNA my Illumina whole genome gene expression array.
Project description:The oncogenic isoform of HER2, HER2D16, was stably overexpressed in the MCF-7 breast tumor cell line (MCF-7/HER2D16) and miR expresion profiles between MCF-7 cell lines expressing a vector control (MCF-7/pcDNA) were compared to the MCF-7/HER2D16 cell line.
Project description:Identifying PDEF regulated genes may shed light on the mechanism by which PDEF may induce breast cancer progression. To that purpose, we have used the MCF-7 human breast tumor cell line model to identify PDEF induced genes. Briefly, PDEF expression was down regulated by shRNA in MCF-7 cells and RNA probes from PDEF-down regulated and control MCF-7 cells were used to screen the Affymetrics HG-U133A Gene Chips. This analysis found 62 genes that were induced 2-fold or higher by PDEF. Further analysis of 3 of these genes namely S100A7, CEACAM6 and B7-H4 in primary breast tumors showed CEACAM6 as a frequently elevated and co-exressed gene with PDEF in these tumors. We previously reported a role for PDEF (prostate derived Ets transcription factor) in breast tumor progression and its association with poor clinical outcome in ER+ breast cancer. To gain further insights into PDEF action in breast cancer, we down regulated PDEF expression by shRNA in MCF-7 human breast tumor cell line, and screened the HG-U133A human gene chips with probes from PDEF down-regulated and control MCF-7 cells. This analysis identified CEACAM6 as one of the genes induced by PDEF. Further analysis of CEACAM6 expression in relation to PDEF in 93 ER+ primary breast tumors showed largely concordant expression of these molecules. To our knowledge, our findings of CEACAM6 as a PDEF induced gene and their elevated co-expression in breast cancer have not been described before. Data from one replicate experiment is included as a representative example of the data obtained. HG-U133A gene chip pairs were screeened with biotinylated RNA probes from PDEF-down regulated MCF-7 cells (experimental) or from control MCF-7 cells.
Project description:Murine prostate cancer cells RM1 were transfected with a fakery murine MXRA7 cDNA in pcDNA3.1 vector. Controls were RM1 transfected with pcDNA3.1 vector. G418 resistant colonies were obtained, and gene expression profiling was performed using Agilent 4*44K array and dual labeling.
