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:This experiment is one of a series of experiments on interspecific recombinant congenic strain (IRCS) mice that aimed to identify novel genes involved in male or female hyporfertility by comparing characteristics of the sperm, number of offspring, quality of implantation etc. in C57B6/J and IRCS mice. <br>The goal of this experiment was to understand the basis of female hypofertility/embryonic resorption in a mouse model of congenic strains. The IRCS strain used in this experiment is the 66H Ch13 mouse. This strain was derived by introgression of a ~6 Mb fragment of mus spretus origin inside the genome of Mus musculus (C57B6/J) (L'hôte et al, Bioessays, 2010. PMID:20091755 ) Previous ultrasonographic analysis of this line revealed an increased rate of embryonic resorption compared to the C57B6/J parent (Laissue et al, Int. J . Dev. Biol, 2009 PMID: 19488966 ). <br>In this experiment we measured gene expression in the tissues that are relevant for implantation and early development, i.e. the uterus and the placenta, in C57B6/J and 66H Chr13 mice at 12 days post-coïtus with C57B6/J males. Pools of RNA from four mice per sample were obtained and analysed using a Nimblegen mouse expression array.
