Project description:Histone methyltransferase SMYD3 knockdown effects in MCF7 breast cancer cell line
| PRJNA248758 | ENA
Project description:From the parental breast cancer cell line MCF7 (weakly invasive), we progressively selected hyperinvasive subclones. We compared the gene expression between the parental MCF7-I0 and the hyper-invasive cells MCF7-I6. We used Affymetrix U133 Plus 2 microarrays to detail the global programme of gene expression underlying weakly and highly invasive breast cancer cells derived from the human breast cancer cell line MCF7.

Project description:The goal of this study is to identify ERalpha-target genes affected by knocking down of the histone arginine methyltransferase CARM1 in MCF7 breast cancer cells. The roles of CARM1 in ERalpha+ breast cancer was not well characterized. Therefore, we created a Dox inducible CARM1 knockingdown MCF7 cell line where CARM1 is decreased to 20% of endogeneous level to determine the created a Dox-inducible CARM1shRNA overexpressing MCF7 cells for evaluation of the global effects of CARM1 on ERalpha-target gene expression.

The roles of CARM1 in ERalpha+ breast cancer was not well characterized. Therefore, we created a Dox inducible CARM1 overexpressing MCF7 cell line where CARM1 is overexpressed by 2 fold to determine the created a Dox-inducible CARM1 overexpressing MCF7 cells for evaluation of the global effects of CARM1 on Eralpha-target gene expression.

Project description:Wild type (wt) MCF7 cells, modelling breast cancer at primary diagnosis, were cultured in phenol red-free RPMI supplemented with 10% FBS and 1nM estradiol (E2). Long-term oestrogen deprived (LTED) cell lines, which model resistance to endocrine therapy, were cultured in phenol red-free RPMI in the absence of exogenous E2 and supplemented with 10% dextran charcoal-stripped bovine serum (DCC). Samples were harvested at baseline and at the point of resistance (LTED). To reveal differential protein abundances between wt-MCF7 and MCF7 LTED, the peptides were labelled with chemical labelling and underwent fractionation using OFFGEL electrophoresis.

Project description:To investigate molecular mechanisms of resistance, we used two different in vivo xenograft models of estrogen receptor-positive (ER+) breast cancer, with or without HER2 over-expression (MCF7/HER2-18 and MCF7 wt, respectively). Mice with established tumors were assigned to the following treatment groups: continued estrogen supplementation (E2), estrogen deprivation (ED), ED plus tamoxifen (Tam), all with or without the EGFR tyrosine kinase inhibitor gefinitinib (G). Another group received ED plus the antiestrogen fulvestrant (MCF7 wt only). Tumors with acquired or de novo resistance to these endocrine therapies were profiled for mRNA expression using Affymetrix Genechip arrays. Keywords: multiple group comparison

Project description:Catechol-O-methyl transferase (COMT) is involved in detoxification of catechol estrogens, playing cancer-protective role in cells producing or utilizing estrogen. Moreover, COMT suppressed migration potential of breast cancer cells. To delineate COMT role in metastasis of estrogen receptor dependent BC, we investigated the effect of COMT overexpression on invasion, transcriptome, proteome and interactome of MCF7 cells, a luminal A breast cancer model, stably transduced with lentiviral vector carrying COMT gene (MCF7-COMT). This PRIDE project includes quantitative analysis results for the total proteome LC-DIA-MS/MS experiment evaluating COMT overexpression in MCF7 breast cancer cell line, and results of pulldown analysis of COMT-interacting proteins in MCF7 cells.
