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

ABSTRACT: 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.

Scientists have injected endotoxin into animals to investigate and understand various pathologies and novel therapies for several decades. Recent observations have shown that there is selective susceptibility to Escherichia coli lipopolysaccharide (LPS) endotoxin in sheep, despite having similar breed characteristics. The reason behind this difference is unknown, and has prompted studies aiming to explain the variation by proteogenomic characterisation of circulating acute phase biomarkers. It i ...[more]

Project description:The Bashbay sheep (Ovis aries), an indigenous breed of Xinjiang, China, has many excellent characteristics. However, hybrids of Argali sheep and Bashbay sheep are susceptible to Mycoplasma ovipneumoniae infection, the causative agent of mycoplasma ovipneumonia, a chronic respiratory disease that is harmful to the sheep industry. To date, knowledge regarding the mechanisms responsible for M. ovipneumoniae pathogenesis is in scant. Herein, we report the results of transcriptome profiling of lung tissues from Argali hybrid sheep experimentally infected with an M. ovipneumoniae strain at 4 and 14 days post-infection, in comparison to mock-infected animals (0 d). Transcriptome profiling was performed by deep RNA sequencing, using the Illumina platform. The analysis of differentially expressed genes was performed to determine concomitant gene-specific temporal patterns of mRNA expression in the lungs after M. ovipneumoniae infection. We found 156 differentially expressed genes (44 up-regulated, 112 down-regulated) when comparing transcriptomic data at 4 and 0 days post-infection, and 367 (35 up-regulated, 332 down-regulated) when comparing 14 versus 0 days post-infection. Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that the differentially expressed genes at 4 and 14 versus 0 days post-infection were enriched in 109 and 150 pathways, respectively, and the Primary immunodeficiency pathway was considered most closely related to MO infection (p < 0.01). Hyper-IgM syndrome was identified based on the B-cell immunodeficiency signaling pathway from differentially expressed genes related M. ovipneumoniae infection. Gene Ontology analysis showed that differentially expressed genes in different groups were enriched for 497 and 928 terms, where those most closely related to M. ovipneumoniae infection are ciliated motor damage (p < 0.01). These results could aid in understanding why the Argali hybrid sheep are susceptible to MO as well as how M. ovipneumoniae infection progresses in the lungs and may provide useful information regarding key regulatory pathways.
