Effect of vaccination, marketing strategy, and bovine respiratory disease development on at arrival transcriptomes of recently weaned beef cattle

ABSTRACT: Jugular whole blood samples (Tempus Blood RNA tubes) were collected and utilized from 43 cattle, specifically from all cattle diagnosed with bovine respiratory disease (BRD) during Texas backgrounding (n=32) and randomly selected cattle never treated for BRD (n=11). Total RNA was isolated from blood samples, and were library prepared and sequenced via Illumina NovaSeq 6000 S4 chemistry. Samples were bioinformatically processed in a HISAT2/StringTie2 pipeline, and stratified based on BRD diagnosis and marketing strategy (Auction versus Direct marketing and transport). Differential expression analysis was conducted in R, utilizing an additive, multifactor generalized linear model and blocking for Mississippi pasture and vaccination status. Genes were considered differentially expressed with an FDR cutoff of 0.05. The objective of this study was to identify differentially expressed genes and mechanisms within and across marketing cohorts with and without BRD.

Multipopulational transcriptome analysis of beef cattle at arrival to identify and further validate candidate biomarkers for predicting clinical bovine respiratory disease

Project description:Objective: Classify and further validate BRD-associated genes and mechanisms found to be differentially expressed at facility arrival in post-weaned beef cattle from multiple independent populations. Our approach was to profile and compare at-arrival whole blood transcriptomes of post-weaned beef cattle that failed to develop symptoms associated with clinical BRD and cattle that ultimately were diagnosed and treated for clinical BRD within the first 28 days of facility arrival, further stratifying diseased animals into severity cohorts. Methods: Whole blood RNA profiles were generated via NGS approach, using an Illumina Novaseq 6000. Individual samples were processed using an adaptation of the Revised Tuxedo Suite protocol (Tuxedo 2), then analyzed in R using edgeR with likelihood-ratio testing. Genes were considered differentially expressed with an FDR cutoff of 0.05. Downstream analysis involved PCA, gene ontology term enrichment, pathway analysis, protein-protein interaction networking, and IPA. Results: 132 differentially expressed genes were identified between all three cohorts. Biological processes and pathways primarily involved neutrophilic activity, antimicrobial killing, cell cornification, and inflammatory signaling/regulation. Conlusions: This study corroborated genes and pathways identified in our previous work, while providing novel genes and pathways for future analysis.

Longitudinal blood transcriptomic analysis to identify molecular regulatory patterns of Bovine Respiratory Disease in beef cattle

Project description:We profiled blood transcriptomics of 24 beef steers at three important stages (Entry: on arrival at the feedlot; Pulled: when sickness is identified; and Close-out: recovered, healthy cattle at shipping to slaughter) to reveal the key biological functions and regulatory factors of BRD and identify gene markers of BRD for early diagnosis and potentially use in selection.

The nasopharyngeal microbiota of cattle with bovine respiratory disease

Project description:The nasopharyngeal microbiota of healthy cattle vs. cattle diagnosed with BRD in a commercial feedlot setting was compared using a high-density 16S rRNA microarray (Phylochip). Nasopharyngeal samples were taken from both groups of animals (n=5) at feedlot entry (day 0) and >60 days later.

Difference in circulating microRNAs between grazing and grain-fed Japanese Black cattle

Project description:We aimed to elucidate the effects of feeding condition (indoor grain-feeding vs. grazing on pasture) on c-miRNAs in Japanese Black (JB) cattle (Wagyu). The cattle at 18 months old were divided into pasture feeding and conventional indoor grain feeding for 5 months. Microarray analysis of c-miRNAs from the plasma extracellular vesicles led to the detection of a total of 202 bovine miRNAs in the plasma, including 15 miRNAs that differed between the feeding conditions.

Influence of vaccination and time on gene expression of healthy backgrounded beef cattle

Project description:Twelve clinically healthy backgrounded cattle (n=6 vaccinated, n=6 non-vaccinated), over four time points (median age in days: 107, 114, 183, 230) were selected for whole blood (Tempus Blood RNA Tubes) mRNA sequencing via NovaSeq 6000 S4 workflow. Sequenced raw reads (~35M/sample) were analyzed for the influence of time (immunological development) and vaccination with a commercial modified live viral multivalent vaccine on host gene expression.

Applying multi-omics data to study the genetic background of bovine respiratory disease infection in feedlot crossbred cattle

Project description:Bovine respiratory disease (BRD) is the most common and costly infectious disease affecting the well-being and productivity of beef cattle in North America. BRD is a complex disease whose development is dependent on environmental factors and host genetics. Due to the polymicrobial nature of BRD, our understanding of the genetic and molecular mechanisms underlying the disease is still limited. This knowledge would augment the development of better genetic/genomic selection strategies and more accurate diagnostic tools to reduce BRD prevalence. Therefore, this study utilized multi-omics data (genomics, transcriptomics, and metabolomics) analyses to study the associations between genome, transcriptome, metabolome, and BRD phenotype of feedlot crossbred cattle. The findings may be useful for the development of genomic selection strategies for BRD susceptibility, and for the development of new diagnostic and therapeutic tools.

Whole blood transcriptome analysis of feedlot cattle with and without bovine respiratory disease

Project description:In this study we aimed to identify differentially expressed (DE) genes involved in the host immune response to BRD using whole blood and RNA sequencing. Samples were collected from heifers (average arrival weight = 215.0 ± 5.3 kg) with (n = 25) and without (n = 18) BRD at a commercial feedlot in Western Canada. RNAseq analysis showed a distinct whole blood transcriptomic profile between BRD and non-BRD heifers. Further examination of the DE genes revealed that those involved in the host inflammatory response and infectious diseases pathways were enriched in BRD animals, while gene networks associated with metabolism and cell growth and maintenance were downregulated. Overall, the transcriptome profile derived from whole blood provided evidence that a distinct antimicrobial peptide driven host immune response was occurring in the animals with BRD.

Transcriptional profiling of peripheral blood - comparison of results obtained from samples stored in two RNA stabilizing reagents

Project description:RNA stabilizing reagents have been developed to ensure that transcription profiles of whole blood samples reflect the physiological state at the time of the blood drawn. Ability to preserve and maintain the in vivo gene expression status ex vivo is essential for gene expression profiling and biomarker discovery from clinical sample material. We compared transcriptional profiles obtained from samples collected using two established peripheral blood RNA collection systems, TEMPUS™ and PAXgene™. We demonstrated that TEMPUS™ and PAXgene™ systems can be used in combination with RiboAmp® mRNA amplification without a need for a separate globin reduction step. However, use of samples collected through different blood collection methods in the same experiment should be avoided.

A composite immune signature parallels disease progression across T1D subjects (RNA-Seq Cohort 0 WB)

Project description:Technical replicate testing was performed to determine the measurement precision of each analyte. Peripheral blood samples were collected in tempus tubes from a healthy control subject with no family history of autoimmunity (n=1) and from subjects with Type 1 diabetes (n=4). Total RNA was isolated independently from 3 replicate aliquots of the same tempus samples and then globin-reduced. RNAseq libraries were prepared from the globin-reduced RNA.
