Project description:Wt1 is required for renal development and homozyogus knockout mice show renal agenesis caused by apoptosis of the metanepric mesnchyme. To identify genes regulated by WT1, we performed comparative gene expression profiling on kidney rudmients of Wt1 heterozygous and homozygous mutant E10.25 embryos.
Project description:Wt1 is required for renal development and homozyogus knockout mice show renal agenesis caused by apoptosis of the metanepric mesnchyme. To identify genes regulated by WT1, we performed comparative gene expression profiling on kidney rudmients of Wt1 heterozygous and homozygous mutant E10.25 embryos. To identify deregulated genes, timed matings were performed and embryos isolated at E10.25, a time point before the onset of apoptosis in Wt1 mutants. The region containing the metanephric mesenchyme was microdissected, RNA isolated and after labeling, hybridized to Mouse Genome Survey Microarrays. Deregulated genes were identified using GeneSpring (GSX) software.

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.

Project description:The Wilms' tumor suppressor gene (WT1) encodes a zinc finger transcription factor that plays important roles during development of several organs including metanephric kidneys. A number of WT1 target genes have been identified, but the detailed mechanisms by which WT1 orchestrates renal development remain elusive. To identify WT1 target genes relevant to development, genome-wide expression profiling was performed using oligonucleotide microarrays representing 39,000 human transcripts Keywords: Wilms' tumor 1 (WT1) gene, -KTS isoform; time course
