Project description:B6 mice were immunized with either 2000 cfu of ova expressing Listeria monocytogenes (LM-ova) or 100ug whle ovalbumin adjuvanted with 50ug polyIC + 50ug anti-CD40 (FGK45). 7 days later, tetramer staining CD8+ T cells from the spleen were flow sorted to purity (~98%), the RNA isolated, reverse transcribed and the resulting cDNA analyzed by gene array MoGene-1_0-st-v1 gene expression determined in naïve (CD44lo) and day 7 post Listeria chalelneg or combined adjuvant vaccine immunization (internally referred to as "synergy").
Project description:Ikbkap/Elp1 regulates genes involved in spermatogenesis. Ikbkap deficiency causes male infertility by disrupting meiotic progression. In this dataset, we include the expression data for control and Ikbkap-knockout mouse testis. We analyzed the gene expression in control and Ikbkap-knockout testes using the the Affymetrix MoGene-1_0-st-v1 platform. Three replicates per genotype.
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:Intestinal epithelial cells (IECs) were isolated from the colon of Villin-CreERT2, Rnf20-flox and Rnf40-flox mice two weeks upon the Tamoxifen-induced, intestinal knockout of Rnf20 and Rnf40. ChIP-seq for H3K4me3 was performed using snap-frozen IECs.
