Global gene expression analysis in murine iPS cells derived with mouse, chick and zebrafish Nanog orthologs

Project description:Nanog null neural stem (NS) cells were reprogrammed to naive pluripotency in 2i/LIF conditions with chick (c) and zebrafish (z) Nanog orthologs. Global gene expression was compared to iPS cells derived with mouse (m) Nanog. Murine iPS cells derived with zebrafish nanog, chick nanog, and mouse nanog orthologs (2 replicates each).

Global gene expression analysis in murine iPS cells derived with mouse and human Nanog orthologs

Project description:Nanog null neural stem (NS) cells were reprogrammed to naive pluripotency in 2i/LIF conditions with mouse (m) Nanog and human (h) Nanog. Global gene expression in resulting iPS cells was compared to embryonic stem (ES) cells and nanog null NS cells. Murine iPS cells derived with mouse nanog iPS and human nanog iPS and then compared to embryonic stem cells and nanog null neural stem cells (3 replicates each).

Global gene expression analysis of Ncoa3 knockdown in mouse embryonic stem cells

Project description:Orphan nuclear receptor Esrrb is vital in maintaining ES cells and like Oct4, Sox2 and Nanog is essential for self-renewal and pluripotency. Esrrb functions in somatic cells via LBD/AF-2-dependent coactivator recruitment to target genes. Here we show that in ES cells coactivator recruitment is similarly required and identify Ncoa3 as the Esrrb coactivator needed for activation of its target genes. Ncoa3 is essential for self-renewal and the induction of pluripotency in reprogramming, and genome-wide analysis of Ncoa3 binding reveals extensive overlap with Esrrb and pluripotency factors along with marks of active genes. Mechanistically, we show Ncoa3 is specifically required to bridge RNApol2 to Esrrb. We thus identify a new member of the ES pluripotency network and describe Esrrb and Ncoa3 as key factors linking core pluripotency factors to the general transcription machinery. Three biological replicates each for control scrambled shRNA and Ncoa3 shRNA transfected E14 mouse ESCs. The global gene expression profiles of Ncoa3 knockdown cells were compared to control scrambled shRNA knockdown cells 4 days post-transfection.

Nanog Independent Reprogramming to iPSCs with Canonical Factors

Project description:It has been suggested that the transcription factor Nanog is essential for the establishment of pluripotency during the derivation of embryonic stem (ES) cells and induced pluripotent stem (iPS) cells. However, successful reprogramming to pluripotency with a growing list of divergent transcription factors, at ever increasing efficiencies, suggests that there may be many distinct routes to a pluripotent state. Here, we have investigated whether Nanog is necessary for reprogramming murine fibroblasts under highly efficient conditions using the canonical reprogramming factors Oct4, Sox2, Klf4 and cMyc. In agreement with prior results, the efficiency of reprogramming Nanog-/- fibroblasts was significantly lower than that of control fibroblasts. However, in contrast to previous findings, we were able to reproducibly generate iPS cells from Nanog-/- fibroblasts that effectively contributed to chimeric mice. Thus while Nanog may be an important mediator of reprogramming it is not required for establishing pluripotency in the mouse, even under standard conditions. In order to further evaluate the equivalency of Nanog null iPSC to nanog null ESCs, we have performed RNAseq on two independent nanog null iPSC lines, as well as Nanog Null ESC, WT ESC and iPSCs as well as MEFs. As a negativve control for reprogramming we have analyzed a partially reprogrammed iPSC line.
