Project description:We report that Zic3 and Esrrb synergistically enhance the reprogramming efficiency when transduced with Oct4, Sox2 and Klf4 (OSK) into murine fibroblasts. By ChIP-seq analysis, we reveal that Zic3 recruits Esrrb to its own binding sites, some of which are proximal to glycolysis-related genes, thereby cooperatively upregulating these genes to activate glycolytic metabolism, and that Esrrb binds to genes related to mitochondrial oxidative phosphorylation. Therefore, our study suggests that Zic3 and Esrrb activate pluripotency gene network by regulating the balance of metabolic pathways.

Project description:Induced pluripotent stem cells (iPSC) are generated from somatic cells by the transgene expression of three transcription factors Oct3/4, Sox2, and Klf4 (OSK), albeit at a low efficiency. The protooncogene c-Myc enhances the efficiency of iPSC generation by OSK, but it also increases the tumorigenicity of the resulting iPSC. In the current study, we found the Gli-like transcription factor Glis1, when expressed together with OSK, to markedly enhance the generation of iPSC from both mouse and human fibroblasts. Mouse iPSC generated by OSK and Glis1 can form germline-competent chimeras. Glis1 is enriched in unfertilized oocytes and one cell-stage embryos. DNA microarray analyses revealed that Glis1 promotes multiple pro-reprogramming pathways, including Myc, Nanog, Lin28, Wnt, mesenchymal-epithelial transition (MET), and Esrrb. These results therefore demonstrated that oocyte transcription factor Glis1 effectively promote direct reprogramming during iPSC generation. p53-null mouse embryonic fibroblasts were transduced with OSK and OSK+Glis1 and were used for microarray analyses.

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. We used microarrays to detail the global programme of gene expression of ES cells, Esrrb reprogrammed iPS cell lines and MEFs. Keywords: comparative
