Leukemia inhibitory factor (LIF) activates the transcription factor signal transducer and activator of transcription 3 (STAT3), which results in the maintenance of mouse embryonic stem cells in the pluripotent state by inhibiting both mesodermal and endodermal differentiation. How the LIF/STAT3 pathway inhibits commitment to both mesoderm and endoderm(More)
Leukemia inhibitory factor (LIF)/STAT3 signalling is a hallmark of naive pluripotency in rodent pluripotent stem cells (PSCs), whereas fibroblast growth factor (FGF)-2 and activin/nodal signalling is required to sustain self-renewal of human PSCs in a condition referred to as the primed state. It is unknown why LIF/STAT3 signalling alone fails to sustain(More)
Embryonic stem (ES) cells have high self-renewal capacity and the potential to differentiate into a large variety of cell types. To investigate gene networks operating in pluripotent ES cells and their derivatives, the "Functional Genomics in Embryonic Stem Cells" consortium (FunGenES) has analyzed the transcriptome of mouse ES cells in eleven diverse(More)
Delineating candidate genes at the chromosomal breakpoint regions in the apparently balanced chromosome rearrangements (ABCR) has been shown to be more effective with the emergence of next-generation sequencing (NGS) technologies. We employed a large-insert (7-11 kb) paired-end tag sequencing technology (DNA-PET) to systematically analyze genome of four(More)
pim-1 and pim-3 encode serine/threonine kinases involved in the regulation of cell proliferation and apoptosis in response to cytokine stimulation. We analyzed the regulation of pim-1 and pim-3 by the leukemia inhibitory factor (LIF)/gp130/signal transducer and activator of transcription-3 (STAT3) pathway and the role of Pim-1 and Pim-3 kinases in mouse(More)
Dehydroepiandrosterone sulfotransferase (DHEA ST) catalyzes the sulfation of DHEA and other hydroxysteroids. DHEA ST enzymatic activity in individual human liver biopsy samples has been shown to vary over a five-fold range, and frequency distribution histograms are bimodal, with approximately 25% of subjects included in a high activity subgroup. We set out(More)
