Project description:We identified genes expressed in mouse liver that are regulated by Cux2, a highly female-specific liver transcription factor whose expression is regulated by sex-dependent plasma GH patterns. Using adenovirus to overexpress Cux2 (Adeno-Cux2) in male liver, we show that Cux2 represses ~35% of male-biased genes and induces/de-represses ~35% of female-biased genes. Adeno-CMV was used as a control for adenoviral infection. (Published in Molec Cell Biology, TL Conforto et al, 2012) Liver RNA isolated from the following eight groups of mice was used in the present study: (1) 8 wk old untreated male (M) mice (n = 10; 5 per each pool); (2) 8 wk old untreated female mice (F) mice (n = 11; 5 or 6 per each pool); (3) 8 wk old male mice treated with Adeno-Cux2 and euthanized 5 days later (n = 12; 6 per each pool); (4) 8 wk old female mice treated with Adeno-Cux2 and euthanized 5 days later (n = 8; 4 per each pool); (5) 8 wk old male mice treated with Adeno-CMV and euthanized 5 days later (n = 13; 6 or 7 per each pool); (6) 8 wk old female mice treated with Adeno-CMV and euthanized 5 days later (n = 7; 3 or 4 per each pool); (7) 8 wk old male mice treated with Adeno-Cux2 and euthanized 3 days later (n=11; 5 or 6 per each pool); (8) 8 wk old male mice treated with Adeno-CMV and euthanized 3 days later (n=11; 5 or 6 per pool). These RNA pools were used in four separate sets of competitive hybridization experiments: 1) 8 wk untreated M vs. 8 wk untreated F; 2) 8 wk M + Ad-Cux2 (5 day) vs. 8 wk M + Ad-CMV (5 day); 3) 8 wk F + Ad-Cux2 (5 day) vs. 8 wk F + Ad-CMV (5 day); 4) 8 wk M + Ad-Cux2 (3 day) vs. 8 wk M + Ad-CMV (3 day). Fluorescent labeling of RNA and hybridization of the Alexa 555-labeled (green) and Alexa 647-labeled (red) RNA samples to Agilent Mouse Gene Expression 4x44k v1 microarrays (Agilent Technology, Palo Alto, CA; catalog # G4122F-014868) were carried out, with dye swapping for each of the three hybridization experiments to eliminate dye bias. Two microarrays, one for each mixed cDNA sample, were hybridized for each of the four fluorescent reverse pairs, giving a total of 8 microarrays.
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: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.
