Comparison of gene expression by sheep and human blood stimulated with the TLR4 agonists lipopolysaccharide and monophosphoryl lipid A [sheep]

ABSTRACT: 11,431 and 4,992 genes were determined in whole blood of healthy human volunteers and normal sheep, respectively following MPLA and LPS exposure Following the exposure 1,029 human and 175 sheep genes were differentially expressed. Of those 175 sheep genes, 54 had a known human ortolog. The major inflammatory mediators, such as IL-1-6-8, TNFa, NFkB, ETS2, PTGS2, PTX3, CXCL18, KYNU, and CLEC4E were similarly (>2-fold) upregulated in both human and sheep blood. Six healthy human volunteers and six normal sheep blood was incubated with LPS or MPLA for 90 minutes, then the blood was transferred to the Paxgene blood RNA tubes and the gene expression microarrays were scanned with G2556 Microaaray Scanner

Towards a comprehensive targeted proteogenomic assay repository for the liquid fraction of sheep blood

Project description:This dataset presents the results of protein sample preparation strategies for enriching a novel encyclopaedic peptide spectral library using the liquid fraction of sheep blood. The method used showed the capability of simultaneously detecting hundreds of key proteins in the liquid fraction of blood (circulating acellular proteome) using sheep as a model by: a) Prototyping of the circulating acellular proteome of healthy sheep using serum b) A comprehensive analysis of fractions of acetone precipitated sheep serum and plasma; c) A comprehensive analysis of fractions of partial organic precipitation of sheep serum and plasma proteins using acetonitrile; d) Combinatorial peptide ligand library protein enrichment of sheep serum and plasma; e) Off-gel fractionation of serum proteins; f) Extraction of protein data from ex-diagnostic sheep serum; g) Derivation of peptide data from serum and plasma of endotoxin treated sheep.

Identification of Prolificacy-related Differentially Expressed Proteins from Sheep (Ovis aries) Hypothalamus by Comparative Proteomics

Project description:Reproduction, as a physiologically complex process, can significantly affect the development of the sheep industry. However, a lack of overall understanding to sheep fecundity has long blocked the progress in sheep breeding and husbandry. Herein, in present study, we aimed to identify differentially expressed proteins (DEPs) from hypothalamus in sheep without FecB mutation in two comparison groups: polytocous (PF) versus (vs.) monotocous (MF) sheep at follicular phase and polytocous (PL) vs. monotocous (ML) sheep at luteal phase,expecting to provide an alternative method to identify DEPs associated with sheep prolificacy from the hypothalamus.

PROTOTYPE OF THE CIRCULATING ACELLULAR PROTEOME OF HEALTHY SHEEP USING SERUM

Project description:This project deals with the characterisation and establishment of the baseline circulating acellular proteome of sheep serum using generic methods. Serum is a readily available substrate for most experimental and clinical applications as evidenced in recent sheep studies. It involves sample preparation for the optimisation of proteomic profiling of sheep serum. The chapter therefore represents the first step in the development of a proteomics pipeline for the detection protein alterations by first establishing the normal proteomic profile of sheep serum.

Profiles of gene expression in skeletal muscle in sheep from the middle gestation to postnatal stages

Project description:Texel and Ujumqin sheep show obvious differences in muscle and fat growth, so they are ideal models not only to understand the molecular mechanism in prenatal skeletal muscle development, but to identify the potential target genes of myostatin. To elucidate the phenotypic variation between the two sheep breeds and the dynamic characteristics of gene expression in skeletal muscle during the development, we examined the development of skeletal muscle in transcriptome-wide level at 70, 85,100,120 , 135 days post coitus (dpc),birth, 1 month and 2 month. Using the specialized and standardized sheep transcriptome-wide oligo DNA microarray (Agilent), we analyzed the transcriptomic profiles of longissmuss dorsi muscle from fetuses of Texel and Ujumqin sheep. We characterized dynamic transcriptome-wide profiles that accompany the prenatal skeletal muscle and fat development in Texel and Ujumqin sheep respectively, and compared the difference in profiles of gene expression between the two sheep breeds at the same developmental stage.Some potential myostatin target genes and other genes controlling the growth of skeletal muscle and adipose were identified for further examinations. Our findings not only contribute to understand the molecular mechanism of prenatal skeletal muscle development in large precocial species, but also provide some clues for human myopathy and obesity at prenatal stages. Moreover, we also can identify putative candidate genes for meat quality traits in farm animals. Longissimus dorsi muscles were sampled from five prenatal development stages (70, 85, 100, 120 and 135 day of gestation) in Texel and eight development stages (at 70, 85, 100, 120, 135 days post coitus (dpc), birth, 1 month and 2 month) in Ujumqin sheep. There were at least three replicates at each development time in each breed. Two gene expression experiments were conducted with a total of 40 hybridizations.

Gene expression in the duodenum of sheep genetically resistant or susceptible to nematodes

Project description:This experiment compared gene expression in the duodenum of [1] weaned genetically resistant sheep and weaned genetically susceptible sheep (84 days old) [2] genetically resistant sheep and genetically susceptible sheep that have been naturally challenged once with nematodes (175 days old) and [3] genetically resistant sheep and genetically susceptible sheep that have been naturally challenged twice with nematodes (276 days old). At each time point (T = 84, 175, 276 days) a four factorial design was used with four resistant animals and four susceptible animals. Each animal in the resistant group was compared to each animal in the susceptible group incorporating dye swaps. At T = 84 the platform GPL4072 was used. At T = 175 days the platform GPL4076 was used and at T =276 days the platform GPL4077 was used.
