Project description:We conducted a high-throughput sequencing study to measure whole brain miRNA expression levels in alcohol naïve animals in the LXS panel of recombinant inbred (RI) mouse strains. We then combined the sequencing data with genotype data, microarray gene expression data, and data on alcohol-related behavioral phenotypes such as 'Drinking in the dark', 'Sleep time', and 'Low dose activation' from the same RI panel.
Project description:This study aimed to perform gene expression quantitative trait locus mapping (eQTL) in the livers of a panel of 36 laboratory inbred strains. Mice were dosed with a saline solution by oral gavage and sacrificed at 24 hours. Livers were removed at sacrifice, RNA was extracted and gene expression was assayed using the Agilent G4121A array. Keywords: eQTL, mouse, liver
Project description:We conducted a timeseries experiment on a recombinant inbred line (RIL) panel of Caenorhabditis elegans derived from a NL5901 x SCH4856 cross. These RILs carry a human alpha-synuclein gene in an N2 and a CB4856 genetic background respectively. We grew synchronized populations of the nematodes (70 RILs, N2, CB4856, NL5901, and SCH4856) under normal conditions (20 degrees Celcius, feeding on Escherichia coli OP50) for 120 hours. The goal of the experiment was to identify loci affecting gene expression in the presence of human alpha-synuclein
Project description:High-density lipoproteins (HDL) are nanoparticles with >80 associated proteins, phospholipids, cholesterol and cholesteryl esters. We have identified and quantified the ultracentrifugation isolated HDL proteome across 93 strains of mice, a diverse inbred strains of mice, Hybrid Mouse Diversity Panel (HMDP).
Project description:Hepatosteatosis underlies several diseases including type 2 diabetes, cardiovascular disease and liver disease. Unfortunately, our understanding of the contributing pathways that initiate and advance hepatosteatosis to subsequent complications is still poorly understood. Here, we take advantage of recent developments in “omics” technologies to perform high resolution proteomics (>5000 proteins) and quantitative lipidomics (>300 lipids) on livers from 107 genetically diverse inbred mouse strains from the hybrid mouse diversity panel. Integration of these data allowed us to define novel regulators of lipid metabolism in the liver.
Project description:Transcriptomes performed on left ventricular heart samples from mice of the hybrid mouse diversity panel, a set of over a hundred inbred strains of mice. In this project, the strains were challenged with Isoproterenol, a beta-adrenergic agonist to induce cardiac hypertrophy and failure. Results are useful for the analysis of heart-related traits in mice
Project description:In order to elucidate the molecular mechanisms underlying individual variation in sensitivity to ethanol we profiled the prefrontal cortex transcriptomes of two inbred strains that exhibit divergent responses to acute ethanol, the C57BL6/J (B6) and DBA/2J (D2) strains, as well as 27 members of the BXD recombinant inbred panel, which was derived from a B6 x D2 cross. With this dataset we were able to identify several gene co-expression networks that were robustly altered by acute ethanol across the BXD panel. These ethanol-responsive gene-enriched networks were heavily populated by genes regulating synaptic transmission and neuroplasticity, and showed strong genetic linkage to discreet chromosomal loci. Network-based measurements of node importance identified several hub genes as established regulators of ethanol response phenotypes, while other hubs represent novel candidate modulators of ethanol responses.
Project description:As part of the PhenoGen Project (https://phenogen.org), kidney RNA-Seq data has been collected from the HXB/BXH recombinant inbred rat panel, which is part 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.
