Project description:We report nuclear receptor Esrrb's responsive genes with or without Esrrb ligand DY131 in DU145 cells. Using Esrrb-null cells, we used RNA-Seq to find Esrrb responsive genes. In addition, we tested DY131-driven Esrrb-dependent genes to test the ligand dependency of Esrrb in regulating gene expression. Control vector transfected cells with vehicle treatment, Esrrb expression vector transfected cell with vehicle treatment, control vector transfected cells with DY131 treatment, Esrrb expression vector transfected cell with DY131 treatment.

Project description:Orphan nuclear receptor estrogen related receptor ? (Esrrb or ERR?) is well known in stem cells and early embryonic development. However, little is known about its function in cancer.We investigated the mRNA profile alterations induced by Esrrb expression and its synthetic ligand DY131 in human prostate cancer DU145 cells via RNA-Seq analysis.We distinguished 67 mRNAs differentially expressed by Esrrb alone. Although DY131 alone did not change any gene, treatment of DY131 in the presence of Esrrb altered 1161 mRNAs. These observations indicated Esrrb had both ligand-independent and ligand-dependent activity. When Esrrb was expressed, DY131 treatment further regulated 15 Esrrb-altered mRNAs. DY131 acted as an antagonist for 11 of 15 mRNAs (wdr52, f13a1, pxdn, spns2, loc100506599, tagln, loc441454, tkel1, sema3f, zcwpw2, sdc2) and as an agonist for 4 of the 15 mRNAs (rarres3, oasl, padi2, ddx60). Gene ontology analyses showed altered genes are related to transcription and translation regulation, cell proliferation and apoptosis regulation, and cellular metabolism.Our results characterized mRNA profiles in DU145 prostate cancer cells driven by Esrrb expression and Esrrb ligand DY131, and provided multiple markers to characterize Esrrb's function in Esrrb research.

Project description:In the murine system, Oct4, Sox2, c-Myc and Klf4 are sufficient to convert fibroblasts to induced pluripotent stem (iPS) cells that exhibit many characteristics of embryonic stem (ES) cells. Herein, we show that the orphan nuclear receptor Esrrb works in conjunction with Oct4 and Sox2 to mediate reprogramming of mouse embryonic fibroblasts (MEFs) to iPS cells. Esrrb reprogrammed cells share similar expression and epigenetic signatures as ES cells. These cells are also pluripotent and can differentiate in vitro and in vivo into the three major embryonic cell lineages. Furthermore, these cells contribute to mouse chimeras and are germline transmissible. In ES cells, Esrrb targets many genes involved in selfrenewal and pluripotency. This suggests that Esrrb may mediate reprogramming through the up-regulation of ES cell-specific genes. Our findings also indicate that it is possible to reprogram MEFs without exogenous Klf transcription factors and link a nuclear receptor to somatic cell reprogramming. Global gene expression effects of silencing the Esrrb gene. We used microarrays to detail the global programme of gene expression after silencing the Esrrb gene. Keywords: time-course Three biological replicates each for control GFP and Esrrb RNAi. The global gene expression profiles of the Esrrb knockdown cells were compared to control GFP knockdown cells for days 2, 4 and 6.

Project description:Porcine induced pluripotent stem cells (piPSCs) could serve as a great model system for human stem cell pre-clinical research. However, the pluripotency gene network of piPSCs, especially the function for the core transcription factor ESRRB, was poorly understood. Here, we constructed ESRRB-overexpressing piPSCs (ESRRB-piPSCs). Compared with the control piPSCs (CON-piPSCs), the ESRRB-piPSCs showed flat, monolayered colony morphology. Moreover, the ESRRB-piPSCs showed greater chimeric capacity into trophectoderm than CON-piPSCs. We found that ESRRB could directly regulate the expressions of trophoblast stem cell (TSC)-specific markers, including KRT8, KRT18 and CDX2, through binding to their promoter regions. Mutational analysis proved that the N-terminus zinc finger domain is indispensable for ESRRB to regulate the TSC markers. Furthermore, this regulation needs the participation of OCT4. Accordingly, the cooperation between ESRRB and OCT4 facilitates the conversion from pluripotent state to the trophoblast-like state.

Project description:Estrogen related receptor beta (Esrrb) is an orphan nuclear receptor that is required for self-renewal and pluripotency in mouse embryonic stem (ES) cells. However, in the early post-implantation mouse embryo, Esrrb is specifically expressed in the extraembryonic ectoderm (ExE) and plays a crucial role in trophoblast development. In this study, to better understand the function of Esrrb in trophoblast lineage cells, we performed microarray analysis of Esrrb-null mutant versus wild-type mouse embryos. To further characterize the regulatory targets of Esrrb, we treated trophoblast stem (TS) cells with either Esrrb inhibitor DES or vehicle and compared their global gene expression profile via RNA-seq analysis. In addition, to ask whether these target genes are directly regulated by Esrrb, we performed Chromatin immunoprecipitation-sequencing (ChIP-seq) analysis of TS cells using anti-Esrrb antibody.
