Project description:We used single nucleus RNA sequencing (snRNA-seq) to analyze the changes in gene expression in treated vs untreated mdx mice and compared them to WT expression
Project description:Duchenne muscular dystrophy is a rare and lethal neuromuscular disease caused by loss-of-function mutations in the dystrophin protein that provides structural integrity to striated muscle fibers. Mice with loss-of-function mutations for the Dmd gene encoding dystrophin (mdx-4cv) were treated with microdystrophin or split-intein AAV constructs to restore various-length dystrophin isoforms to the skeletal muscle compartment. The aim of this study was to compare protein expression profiles between healthy (WT), mdx-4cv, and AAV-treated mdx-4cv gastrocnemius skeletal muscle. We employed an isobaric labeling TMT multiplex discovery proteomics approach to describe and compare proteomic profiles across experimental 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:Two iodoTMT 6-plex screens were used to assess the changes in protein cysteine oxidation following eccentric contractions in extensor digitorum longus (EDL) muscles that were extracted from wild type and mdx mice and treated with and without 750uM sodium hydrogen sulfide (NaHS). N=5 for each group: WT, WT+ECC, mdx, mdx+ECC, and mdx+ECC+NaHS.
