Project description:The Yeast Artificial Chomosome (YAC) 128 model of Huntington's disease shows substantial deficits in motor, learning and memory tasks and alterations in its transcriptional profile. We examined the changes in the transcriptional profile in the YAC 128 mouse model of HD at 6, 12, and 18 weeks Brain striatal tissue from Wild Type and YAC 128 mice were sampled at the three age groups

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:To describe the protein profile in hippocampus, colon and ileum tissue’ changing after the old faeces transplants, we adopted a quantitative label free proteomics approach.
Project description:To understand the effects of learning on expression in mouse striatum, we combined an automated operant conditioning chamber (OCC) setup with an efficient RNA-sequencing protocol. We compared 450 striatal expression profiles from 75 mice, e.g., the data contains 6 samples per mouse. Biopsies were taken from both hemispheres, three striatal regions (dorsoventral, dorsomedial, ventromedial striatum) at three learning stages (Early, Intermediate, Late). For each learning stage, there is the same number of samples from paired yoked control mice. There are also samples from control mice that were not kept in OCCs (Naive). The processed data can also be assessed and downloaded from here https://shiny.bio.lmu.de/Dopaloops/
