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:Gene expression profiling of prefrontal cortices of mice subjected to acute and chronic social stress
| PRJNA271746 | ENA
Project description:Social stress is well known to be involved in the occurrence and exacerbation of mental illness, and also various life-style related diseases such as hyperinsulinemia, hyperglycemia, cardiovascular diseases and cancer. However, there is little information on tissue-specific gene expression in response to social stress, which reflects our daily life. Liver is one of the most important organs, owing to its biological functions such as energy metabolic homeostasis, metabolization and detoxification of endo- and exogenous substances. In order to elucidate the mechanism underlying response to social stress in the liver, we investigated hepatic gene expression in mice exposed to isolation stress using DNA microarray. Male BALB/c mice (4 weeks old) were housed 5 per cage for 10 days acclimatization. Then mice were exposed to isolation stress for 30 days. After stress treatment, the mouse liver RNA was subjected to DNA microarray analysis. Taking the false discovery rate into account, isolation stress altered expression of 420 genes. Moreover, Gene Ontology analysis of these differentially expressed genes indicated that isolation stress remarkably down-regulated lipid metabolism-related pathway through peroxisome proliferator-activated receptor-ï¡ (PPARï¡), while lipid biosynthesis pathway regulated by sterol regulatory element binding factor-1 (SREBF-1), Golgi vesicle transport and secretory pathway-related genes were significantly up-regulated. These results suggested that isolation for 30 days, mild and consecutive social stress, not only regulate the systems for lipid metabolism but also cause the endoplasmic reticulum stress in mouse liver. Experiment Overall Design: Male BALB/c mice (4 weeks old, Japan SLC, Shizuoka, Japan) weighing 14-18 g were housed 5 per cage. After acclimatization for 10 days, the mice were exposed to isolation (1 mouse per cage). All cages were placed in a foam plastic box in order to avoid social contact. To enhance the feeling of isolation, the bed volume in each cage for the isolated mice was reduced to one-tenth of that in the control group. The weight of bedding chips was about 2 g. All mice were housed in an air-conditioned room ( room temperature: 23 ± 1°C, humidity: 55 ± 5 %) under 12 h dark/12 h light cycles, with free access to tap water and MF diet (Oriental Yeast Co., Tokyo, Japan).

Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility. Gene expression was measured in whole testis from males aged 62-86 days. Samples include 190 first generation lab-bred male offspring of wild-caught mice from the Mus musculus musculus - M. m. domesticus hybrid zone.
