Project description:Methylated DNA binding protein 2 (MBD2) has been shown to bind specific methylated promoters and suppress transcription. Here we systematically investigate MBD2 suppression by overexpressing MBD2 in MCF-10A cells and generating gene expression profiles of overexpressing cells and normal MCF-10A cells.

Here we systematically investigate MBD2 suppression by overexpressing MBD2 in MCF-10A cells and generating gene expression profiles of overexpressing cells and normal MCF-10A cells. MCF-10A cells were infected with MBD2 lentivirus in order to increase MBD2 expression. Total RNA was extracted from both infected and non-infected cells and hybridized to Affymetrix gene expression microarrays. Three technical replicates were hybridized for infected and non-infected cells.

Here we systematically investigate MBD2 suppression by overexpressing MBD2 in MCF-10A cells and generating genome-wide promoter methylation profiles in order to identify methylation changes likely to affect gene expression levels.

MCF-10A cells were infected with MBD2 lentivirus in order to increase MBD2 expression. DNA was extracted from both infected and non-infected cells and enriched for methylated DNA through the method of methylated DNA immunoprecipitation (MeDIP). Enriched and total DNA was hybridized in different channels to 244K custom microarrays (Agilent Technologies) that contained probes covering at 100bp-spacing all transcription start sites from -800bp to 200bp (human, Ensembl v44) and all microRNAs in miRBase from 250bp before to 250bp after the microRNA. Three technical replicates were hybridized for infected and non-infected cells.
Project description:Microarray analyses with cells/tissues overexpressing YAP have revealed many transcription targets of YAP (Dong et al, 2007; Zhao et al, 2008). However, as YAP induces transformation of non-cancerous cells, we thought many of known targets of YAP may be indirect consequence of transforming property of YAP. To identify the immediate transcription targets for YAP, we utilized immortalized mammary epithelial MCF-10A cells expressing a tamoxifen inducible, hyperactive (S127/381A) YAP mutant (MCF-10A ERT2-YAP 2SA). MCF-10A ERT2 and MCF-10A ERT2-YAP 2SA are generated. Each cell line was treated with 0.1% of ethanol (solvent) or 1uM of 4-hydroxytamoxifen for 2 or 6 hours. This makes 6 samples per set. The experiments were done in duplicate. The expression data from MCF-10A ERT2 and MCF-10A ERT2-YAP 2SA before tamoxifen treatment can serve as control.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:To investigate the mechanisms of PI3Kα-induced senescence, we performed a gene expression microarray analysis with MCF-10A/H and parental MCF-10A cells.
