Project description:Mouse primary hepatocytes (MPH) prepared from C57Bl6 male adult mice were challenged with the FXR agonist GW4064 and used to prepare RNA which was then processed for analysis using MoGene-2_0-st Affymetrix microarrays according to standard procedures.
Project description:We report the genome-wide profiling of FXR binding by ChIP-seq from GW4064 or DMSO treated primary human hepatocytes. We reported altered RNA expression profiles in primary human hepatocypes upon GW4064 treatment compared to DMSO control by RNA-seq. We also reported the altered RNA expression profiles in livers from WT C57BL/6J mice upon GW4064 treatment compared to vehicle control. Primary human hepatocytes were treated with 5uM GW4064 or DMSO control, 1 hour later, cells were fixed and collected for chromatin isolation. 24 hours post treatment, cells were isolated for RNA isolation. This submission represents HTS component of study.

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.
