Project description:Gene expression profiles of ZHBTc4 ES cells expressing EGFP, Oct4-EGFP, Nr5a2-EGFP under CAG promoter. Monoclonal cell lines selected by Puromycin were used for analysis. Each of the cell lines was cultured in doxycycline containing media for endogenous Oct4 knock-down. Pupose of this experiment is to investigate the possibility that forced expression of Nr5a2 can replace Oct4 function in the self-renewal of ES cells. Monoclonal ZHBTc4 ES cells expressing EGFP vs Nr5a2-EGFP, Oct4-EGFP vs Nr5a2-EGFP, no replication

Project description:Nr5a2 (also known as liver receptor homolog-1, Lrh-1) has been shown to bind both the proximal enhancer and proximal promoter regions of Pou5f1 and regulate Pou5f1 in the epiblast stage of mouse embryonic development (Gu et al., 2005). Nr5a2-null embryos display a loss of Oct4 expression in the epiblasts (Gu et al., 2005) and die between E6.5 and E7.5 (Gu et al., 2005; Pare et al., 2004). To identify the targets of Nr5a2, we generated a stable ES cell-line that expresses HA-tagged Nr5a2. Anti-HA antibody was used to immunoprecipitate HA-Nr5a2 for ChIP-seq analysis. Keywords: Transcription factor binding sites To identify the binding sites of Nr5a2, we generated a stable ES cell-line that expresses HA-tagged Nr5a2. Anti-HA antibody was used to immunoprecipitate HA-Nr5a2.

Project description:ChIP-seq using anti-GFP antibody to map genomic binding of Prdm4-EGFP in stably transfected mouse embryonic stem cells Two independent ChIP-seq replicates for each of two independent Prdm4-EGFP expressing ES cell clones resulting in four anti-GFP ChIP-seq experiments. These samples have paired mouse IgG control.
