Project description:Background: Transcriptomic variation among cattle breeds and their crossbreds may help to better understanding of consequences of crossbreeding and heterosis. In this study the differences in biological functions and pathways of three crossbreds including 50 and 75 percent Holstein were compared with their purebred parents, Holstein and Taleshi (an indigenous breed) cattle. Results: Five populations and their ten comparisons were studied by bioinformatics tools for transcriptome analysis. We pooled blood RNA of at least 8 animals of each population prior to RNA sequencing. The obtained results showed that total expressed transcripts in all populations were 72,812 with 22,627 annotated genes. Functional analysis of differentially expressed genes (DEGs) showed that the genetics information processing and metabolism were the most highly-impacted pathways. Among all significantly enriched pathways, eukaryotic translation initiation factor-2 signaling had the highest activation z-score (5.3) in crossbred compared to purebred cattle. The majority of upstream regulators of genes including transcription regulators and cytokines were differentially expressed among populations in which their activation z-score in purebred was more than crossbred cattle. Conclusions: Crossing of Holstein with Taleshi breed resulted in higher activity of pathways related to genetic information processing and lower activity of pathways related to immunity and inflammatory responses. To the best of our knowledge, this is the first study where the differences in pathways and functions were studied using high throughput sequencing of blood in a cattle crossbreeding program. The analysis revealed that the most important differences between studied genotypes, especially between purebred and crossbred cattle, were related to immune functions and metabolism.

Project description:Bovine tropical theileriosis is a major haemoprotozoan disease associated with high rates of morbidity and mortality particularly in exotic and crossbred cattle. It is one of the major constraints for of the livestock development programmes in India and southern Asia. Indigenous cattle (Bos indicus) are less affected by this disease than exotic and crossbred cattle. Genetic basis of resistance to tropical theileriosis in indigenous cattle is not well studied. Recent studies gives an idea that differentially genes expressed in exotic and indigenous breeds play an important role in breed specific resistance to tropical theileriosis. The present study was designed to visualize the global gene expression profiling in PBMCs derived from indigenous (Tharparkar) and crossbred cattle with in vitro infection of T. annulata. T. annulata Parbhani strain, originally isolated from Maharashtra (India) and maintained as cryopreserved stabilates of ground-up tick tissue sporozoite (GUTS) of infected H. anatolicum anatolicum was used as infective material. Two separate microarray experiments were carried out using separately each for crossbred and Tharparkar cattle. The crossbred cattle showed 1082 differentially expressed genes (DEGs). Out of total DEGs, 597 genes were downregulated and 485 were upregulated. Their fold change varies from 2283.93 to -4816.02. Tharparkar cattle showed 875 differentially expressed genes. Out of total DEGs in Tharparkar cattle, 451 genes were downregulated and 424 genes were upregulated. Their fold change varies from 94.93 to -19.20. A subset of genes was validated by quantitative RT-PCR and results correlated well with data obtained from the microarrays indicating that the microarray results gave an accurate report of transcript level. Functional annotation study of differentially expressed genes has confirmed their involvement in various pathways including response to oxidative stress, immune system regulation, cell proliferation, cytoskeletal changes, kinases activity and apoptosis. Gene network analysis of these differentially expressed genes provided an effective way to understand the interaction among them. It is therefore, hypothesised that the dissimilar susceptibility to tropical theileriosis exhibited by indigenous and crossbred cattle is due to breed-specific differences in the interaction of infected cells with other immune cells, which ultimately influences the immune response generated against T. annulata infection. Global gene expression profiling in PBMCs derived from indigenous (Tharparkar) and crossbred cattle were studied after in vitro infection of T. annulata Parbhani strain at 2h time period. Two separate microarray experiments were carried out using Bovine (V2) Gene Expression Microarray, 4x44K (Agilent). Two biological replicate samples were profiled per condition (i.e. replicates samples each in crossbred and Tharparkar cattle).

A customized bovine Combimatrix microarray containing 10,199 genes were constructed, and transcripome of longissimus dorsi muscle was compared between Korean cattle bulls (3 bulls) and steers (3 high-marbled and 3 low-marbled steers) by using the microarray hybridzation.

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.

Project description:The incidence of sub-fertility is higher in crossbred bulls compared to zebu bulls. In the present study, we analysed the metabolomic profile of seminal plasma from crossbred and zebu bulls and uncovered differentially expressed metabolites between these two breeds. Using a high-throughput LC-MS/MS-based approach, we identified 990 and 1,002 metabolites in crossbred and zebu bull seminal plasma respectively. After excluding the exogenous metabolites, we found that 50 and 68 putative metabolites were unique to crossbred and zebu bull seminal plasma, respectively, whilst 87 metabolites were common to both. After data normalisation, 63 metabolites were found to be dysregulated between crossbred and zebu bull seminal plasma. Observed pathways included Linoleic acid metabolism (observed metabolite was phosphatidylcholine) in crossbred bull seminal plasma whereas inositol phosphate metabolism (observed metabolites were phosphatidylinositol-3,4,5-trisphosphate/inositol 1,3,4,5,6-pentakisphosphate/myo-inositol hexakisphosphate) was observed in zebu bull seminal plasma. Abundance of Tetradecanoyl-CoA was significantly higher, whilst abundance of Taurine was significantly lower in crossbred bull seminal plasma. In conclusion, the present study established the seminal plasma metabolomic profile in crossbred and zebu bulls and suggest that increased lipid peroxidation coupled with low concentrations of antioxidants in seminal plasma might be associated with high incidence of sub-fertility in crossbred bulls.
