Project description:To study the effect of pregnancy on mouse mammary epithelial subpopulations, epthelial cells derived from control or ovariectomized adult mice were isolated using fluorescence-activated cell sorting. After elimination of haematopoietic and endothelial cells, two distinct epithelial subpopulations were sorted using antibodies against CD29 and CD24. Based on the immunohistochemical phenotype, and in vivo and in vitro functional assays, these subpopulations were identified as mammary stem cell enriched (CD29hiCD24+) and luminal (CD29loCD24+) respectively (ref: Shackleton et al, Nature 2006). Microarray profiling was used to compare gene expression profiles of the two subpopulations isolated from ovariectomized and control mice.

Microarray profiling was used to compare gene expression profiles of the two subpopulations isolated from ovariectomized and control mice. For each of two biological replicates, 6 FVB/NJ mice were ovariectomized at 8 weeks of age. 4 weeks after ovariectomy (Ovx) mammary gland from control or Ovx animals were collected and digested to obtain a single cell suspension. CD45-CD31-TER119- cells were then sorted based on the expression of cell surface markers CD24 and CD29. Similarly for two pools of control mice. There were also 4 technical replicates, to make 12 BeadChips in total.

Project description:This study examined the effect of early pregnancy on the gene expression profiles of stromal and various epithelial mammary cell subpopulations in mice. Mammary cell subpopulations were isolated from parous and age-matched virgin control mice. Three independent replicates were assessed per cell subpopulation and treatment group, resulting in a total of 35 samples.

Project description:In this study we mapped H3K27me3, H3K4me3 and H3K9me2 marks in three mammary epithelial subsets: MaSC/basal (MS), luminal progenitor (LP) and mature luminal (ML) in the steady-state. In addition, profiles were generated for H3K4me3 and H3K27me3 marks in the MaSC/basal and luminal populations from the glands of ovariectomized or mid-pregnant (12.5 days) mice as well as from control virgin mice. We used ChIPseq analysis to determine histone modification marks in the MS, LP and ML subsets in the steady-state. We then determined the histone modification profiles of MS and sorted luminal (Lum) cells from pregnant (12.5 dP) or ovariectomized (OVX) mice and compared these with the profiles of control virgin mice in order to study the effect of hormones on the mammary epigenomes.

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.
