Project description:We used microarrays to identify Pax3 targets during myogenesis in the mouse embryo Mouse embryos were genotyped Pax3GFP/+ or Pax3PAX3-FKHR/GFP and dissected at E10.5 under a fluorescent binocular. The forelimb buds were dissected and dissociated and GFP positive cells were then sorted by flow cytometry before RNA extraction and hybridization on Affymetrix microarrays. We also sorted GFP negative cells.

Project description:Polycomb group (PcG) proteins play a pivotal role in epigenetically silencing development-related genes, restricting their expression to appropriate tissues. However, in some instances PcG target genes must also be dynamically regulated in response to developmental signals encountered during morphogenesis. Here we examine the role of PcG factors in early forelimb bud patterning, a process that relies on various morphogenetic signals. Depletion of Ring1 proteins, which are essential components of Polycomb repressive complex-1 (PRC1), led to dramatic deficiencies in forelimb formation and proximal-distal regionalization. Gene expression analysis identified Meis2 and Meis1 as critical PRC1 targets genes in early distal specification, with PcG proteins counteracting retinoic acid (RA) signaling to control their expression. Importantly, in this system, PcG factors appear to function by adjusting the threshold for RA signaling, revealing an unexpected role of polycomb proteins in dynamic gene regulation during development. [Affymetrix] Mouse E10.5 forelimb buds of Ring1A-KO, Ring1A/B-dKO and RA-treated wild type were used for RNA extraction and hybridization on Affymetrix microarrays.

Project description:We report time-series transcriptome of developing bamboo shark fin buds and mouse forelimb buds, and open chromatin regions of developing mouse forelimb buds. The major contributions of this study are 1) transcriptomic data with an accurate orthology map for a systematic comparison between the two species; 2) high quality chromatin accessibility data for mouse limb development; 3) discovery of mass heterochronic genes between fins and limbs; 4) hourglass-shaped conservation between fins and limbs, providing insights into a general trend of gene regulatory evolution.

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.
