Genome-wide profiling of H3K27ac, H3K4me1, H3K27me3 and H3K9me3 (ChIP-seq) in U2OS-GR and U2OS-AR cells

ABSTRACT: We performed ChIP-seq targeting the H3K27ac, H3K4me1, H3K27me3 and H3K9me3 in the U2OS-GR and U2OS-AR cell lines. The cell lines are derived from U2OS ATTC:HTB-96 and stably transfected with an expression construct for either rat GR or human AR, respectively. The U2OS-GR cells were treated with dexamethasone (1 µM) or vehicle (ethanol) for 90 minutes. The U2OS-AR cells were treated with R1881 (5 nM) or vehicle (DMSO) for 4 hours.

Studying enhancer activity by FAIRE-STARR-seq in the U2OS-GR and the U2OS-AR cells upon hormone treatment

Project description:To quantify functional enhancers, we performed STARR-seq (Self-Transcribing Active Regulatory Region sequencing) in the U2OS-GR and the U2OS-AR cell lines (derived from U2OS ATTC:HTB-96, stably transfected with an expression construct for rat GR or human AR, respectively). U2OS-GR cells were treated with dexamethasone (1 µM) or vehicle (ethanol) for 14 hours. U2OS-AR cells were treated with R1881 (5 nM) or vehicle (DMSO) for 14 hours. To limit the number of putative enhancers, the STARR library contained genomic regions isolated by FAIRE (Formaldehyde Assisted Isolation of Regulatory Elements) from dexamethasone-treated U2OS-GR cells to include regions that gain accessibility upon GR activation. We added unique molecular identifiers (UMIs) during the reverse transcription stage to facilitate quantitative measurements of enhancer activity for each fragment. The UMI for each read is present within the sequence identifier line (directly following the y coordinate and separated by a ':') of the fastq files.

Glucocorticoid receptor profiling in IMR90,K562 and U2OS (ChIP-seq)

Project description:To identify the sequences responsible for recruitment of Glucocorticoid receptor (GR) to individual loci, we performed ChIP-seq and ChIP-exo that combines chromatin immunoprecipitation with an exonuclease digestion step. We performed these experiments in three cell lines : IMR90 (ATTC:CCL-186), U2OS osteosarcoma cell lines, K562 (ATCC:CCL243), upon glucocorticoid treatment. The U2OS assays are the same as those in E-MTAB-2731.

SUMOylation Regulates the Anti-Proliferative Gene Signature Programs of Glucocorticoid Receptor (U2Os cell line)

Project description:In addition to the glucocorticoids, the glucocorticoid receptor (GR) is regulated by post-translational modifications, including SUMOylation. We have analyzed how SUMOylation influences the activity of endogenous GR target genes and the receptor chromatin binding by using isogenic HEK293 cells expressing wild-type GR (wtGR) or SUMOylation-defective GR (GR3KR). Gene expression profiling revealed that both dexamethasone up- and down-regulated genes are affected by the GR sumoylation and that the affected genes are significantly associated with pathways of cellular proliferation and survival. The GR3KR-expressing cells proliferated more rapidly and their anti-proliferative response to dexamethasone was less pronounced than in the wtGR-expressing cells. ChIP-seq analyses indicated that the SUMOylation modulates the chromatin occupancy of GR on several loci associated with cellular growth in a fashion which parallels with their differential dexamethasone-regulated expression between the two cell lines. Moreover, genome-wide SUMO-2/3 marks, which were generally associated with active chromatin, showed markedly higher overlap with the wtGR cistrome than with the GR3KR cistrome. In sum, our results indicate that the SUMOylation does not simply repress the GR activity, but regulates the activity of the receptor in a target locus selective fashion, playing an important role in controlling the GR activity on genes influencing cell growth. Total RNA isolated from U2Os cell lines stably expressing either wild-type GR (wtGR) or SUMOylation-defective GR (GR3KR) treated with either vehicle (EtOH) or 100 nM of dexamethasone (dex) for 6h.
