Project description:Identification of localization patterns for different histone modifications and transcription activators in parental and resistant cells
Project description:To investigate the functional outcome of PARP1 activation, we performed a pull-down assay coupled with comparative mass spectrometry (MS) analysis to identify proteins that are specifically associated with PAR-PARP1.
Project description:This SuperSeries is composed of the following subset Series: GSE28948: TMPRSS2-ERG, HDACs and EZH2 are involved in an AR-centric transcriptional circuitry that calibrates androgenic response for prostate cancer progression (gene expression data) GSE28950: TMPRSS2-ERG, HDACs and EZH2 are involved in an AR-centric transcriptional circuitry that calibrates androgenic response for prostate cancer progression (ChIP-Seq data) GSE35540: TMPRSS2-ERG, HDACs and EZH2 are involved in an AR centric transcriptional circuitry that calibrates androgenic response for prostate cancer progression (gene expression after ERG KD) Refer to individual Series
Project description:To detect the direct target genes of H3K4me3 in decidual stromal cells, decidual stromal cells are collected and subjected to ChIP-Seq. After aligned to mouse mm10 by STAR, peaks are called by MACS2. We found that H3K4me3 was significantly enriched at the transcription start site (TSS) of expressed genes (RPKM>1). A direct comparison of Menin and H3K4me3 ChIP-seq peaks at gene promoters showed a significantly strong positive correlation (R2=0.5888291). The promoters of 6,800 genes bound by Menin (92% of all genes with promoter bound by Menin) were also H3K4me3 modified.
Project description:We investigated the RNAPII and γH2AX occupancy genome wide by ChIP-Seq in MLL2 F/F and FC/FC80 MEF cells. We found that a week after MLL2 excision (FC/FC cells), a group of genes present higher levels of γH2AX and RNAPII near the TSS, as compared to the control (F/F cells). H3K4Me1, H3K4M2 and H3K4Me3 levels near the TSS were also studied. There is a total of 52 samples. 3 independent replicates for each experiment were performed. H3, H2AX and IgG ChIPs were used for normalisation or as controls.The experiments were performed using immortalised mouse embryonic fibroblasts (MEF) in which both MLL2 alleles were targeted by the loxp system (F/F cells). Tamoxifen treatment of the F/F cells for 24 hours results in the excision of both MLL2 alleles (FC/FC cells).
