Project description:This SuperSeries is composed of the following subset Series: GSE28239: Identification and functional impact of genomic copy number variants in zebrafish, an important human disease model (Zebrafish Strain CNVs) (expression array) GSE28276: Identification and functional impact of genomic copy number variants in zebrafish, an important human disease model (Zebrafish Strain CNVs) (CGH ZV81M) GSE28278: Identification and functional impact of genomic copy number variants in zebrafish, an important human disease model (Zebrafish Strain CNVs) (CGH ZV81M 2) GSE33962: Extensive genetic diversity and substructuring among zebrafish strains revealed through copy number variant analysis (CGH) Refer to individual Series
Project description:Copy number variants (CNVs) represent a substantial source of genomic variation in vertebrates, but the zebrafish reference genome has no annotated CNV information. We further analyzed zebrafish CNVs using pooled samples of 10 zebrafish each from three laboratory strains (AB, Tubingen, and WIK) to identify strain specific CNVs between groups. 10 zebrafish from 3 laboratory strains were pooled and run against the other pooled samples resulting in three array combinations.
Project description:Polycomb group (PcG) mutants were first identified in Drosophila based on their failure to maintain proper Hox gene repression during development. The proteins encoded by the corresponding fly genes mainly assemble into one of two discrete Polycomb Repressive Complexes: PRC1 or PRC2. However, biochemical analyses in mammals have revealed alternative forms of PRC2, and multiple distinct types of non-canonical or variant PRC1. Through a series of proteomic analyses, we identify analogous PRC2 and variant PRC1 complexes in Drosophila, as well as a broader repertoire of interactions implicated in early development. Our data provide strong support for the ancient diversity of PcG complexes, and a framework for future analysis in a longstanding and versatile genetic system.

Project description:Paenarthrobacter nicotinovorans pAO1 is a nicotine degrading microorganism that shows promising applications in converting nicotine-containing waste into useful green chemicals. Its biotechnological applications are nevertheless hampered by the lack of knowledge and tools to perform genetic and metabolic engineering. The objective of the work is to provide the first transcriptome of the strain and is a second step in our envisioned complete omics characterization of nicotine metabolism in P. nicotinovorans ATCC 49919.

Project description:To begin to understand how variations in the genome drive changes in the skeletal muscle proteome, we performed a proteomic analysis of Gastrocnemius muscle from 73 inbred mouse strains of the Hybrid Mouse Diversity Panel (HMDP) that were fed a chow diet and housed under identical environmental conditions (n=2-4; 162 mice). These data were integrated with genomic and various molecular/phenotypic data via systems genetic analysis which is a powerful forward genetics approach to identify potential new regulators of complex traits. Proteomics was performed with eighteen 10-plex tandem mass tags (TMT) experiments each consisting of 9 strains plus a pooled common internal reference. Peptides were analysed by 2D-liquid chromatography coupled to tandem mass spectrometry (2D-LC-MS/MS) resulting in the quantification of 5,350 proteins with 4,027 quantified in >50 mice and 2,069 proteins quantified in all 162 animals.
Project description:affy_cellwall_maize - affy_cellwall_maize - Maize, Zea mays, is one of the most widely grown crops in the world as it provides cereal grain for human purposes and feedstock for cattle. Maize is increasingly used as a biomass fuel, such as ethanol. Studies have shown that maize stem is made up of different lignified cell types: epidermis, sclerenchyma (a few layers under the epidermis and surrounding vascular bundles in the rind), parenchyma (mostly lignified near the epidermis). One of the aims of this work is to find out if it is the proportion of these different cell types or their number (especially for vascular bundles) which influences the degree of digestibility of maize lines. For that the objective of our work is to develop a genomic strategic approach allowing an improvement of traits involved in cell wall degradability. The work will include the mapping of genes considered as strategic in the cell wall biosynthesis, the search of new genes of interest through bio-analysis, the functional analysis of genes suspected to be of importance in cell wall pathway, the search of candidate underlying QTL, and transcriptomic approaches in order to find genes co-regulation, transcription.-Comparison of internodes from 5 maize lines grown in field conditions 10 arrays - maize; organ comparison
Project description:We report transcriptomic profiling from bulk heart, kidney, and liver tissues for 58 strains of the inbred mouse Collaborative Cross (CC). Each strain is represented by a male/female pair. Reads were first aligned to the pooled transcriptomes of the eight founder strains of the CC and then total gene counts were quantified using the EMASE and GBRS software tools. Total read counts can be further normalized for use in differential gene expression analysis, expression quantitative trait locus (eQTL) analysis, and integrative analyses with other -omic data sets measured on the same samples, including proteomics and phosphoproteomics.
Project description:As part of the PhenoGen Project (https://phenogen.org), liver RNA-Seq data has been collected from strains of the Hybrid Rat Diversity Panel (HRDP). RNA expression levels were estimated using high throughput RNA sequencing (RNA-Seq) on long (>200 nucleotides) RNAs, i.e., total RNA where ribosomal RNA was depleted. These data can be used to examine predisposition phenotypes in the HRDP. Processed data and interactive graphics are also available through the PhenoGen website. Additional data from additional strains will be added as they become available.
