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. Mouse embryonic fibroblasts were transduced with OSKM, OSM+Glis1, OSM+Dmrtb1, and OSM+Pitx2 and were used for microarray analyses.

Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.
