Project description:Transgenic mouse study on proteomic effects of selective 50-kDa C-terminal domain of IRE-BP1 over-expression in islets versus wild-type/back-ground strain.
Project description:Previous studies have demonstrated elevated circulating levels of PANcreatic DERived factor (PANDER) overexpression induced a selective hepatic insulin resistant phenotype in the liver of the PANDER transgenic mouse model. Here we utilized SILAC for "spike-in" as a quantitative mass spectrometry based proteomic workflow to reveal proteomic profile changes between the PANDER transgenic mouse and the wild-type mouse.

Project description:In this study we analysed the proteome of transforming growth factor β-induced protein (TGFBIp) R124H transgenic mouse corneas in an attempt to understand the disease mechanisms leading to the granular corneal dystrophy type 2. The transgenic mouse model was generated by insertion of human TGFBI cDNA with the R124H mutation into the first exon of the mouse TGFBI DNA generating the transgenic TGFBIR124H mouse model We compared the corneal proteome of three wild-type, heterozygous, and homozygous mice of different genders, which were age-matched and analysed the proteolytic processing and relative amount of TGFBIp. No protein deposits were observed in the investigated corneas.
Project description:Transcription profiling of mouse development The experiment were perfomed as a part of our Vertebrate Evo-Devo project. The aim of the project is to compare transcription profiles of normal (unmanipulated, wild-type, whole embryo) vertebrate embryos.
Project description:Myosine heavy chain I was overexpressed in mouse skeletal muscle. The transgenic mice, as well as the wild type mice, were endurance trained on treadmill for 5 days/week over 8 weeks at 80% peak aerobic capacity in comparison with untrained mice. The gene expression profiles of the skeletal muscles from wild-type trained (WTT) and untrained (WTUT), and transgenic trained (TGT) and untrained (TGUT) were measured using Affymetrix Mouse430A 2.0 GeneChips. Keywords: genetic modification

Project description:To investigate global genome expression changes caused by the ectopic expression of CsMYBF1, we compared the gene expression profiles of the transgenic and wild type tomato fruits by RNA-seq analysis.Fruit samples from at least five plants of each genotype, which were harvested between 7 and 10 days after breaker stage, were pooled for total RNA isolation.A total of 3296 genes were differentially expressed between the transgenic and wild type fruits, and most of them were significantly induced, indicating the widespread influence on the expression of the endogenous tomato genes.
