Deciphering metabolomic alterations in seminal plasma of crossbred (Bos taurus X Bos indicus) bulls through comparative deep metabolomic analysis

ABSTRACT: 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.

Project description:The importance of parental diet in relation to eventual offspring health is increasing in prominence due to the increased frequency of reproductive age adults consuming poor diets. Whilst maternal health and offspring outcome have been studied in some detail, the paternal impacts are not as well understood. A father’s poor nutritional status has been shown to have negative consequences on fetal growth and development and ultimately impact the long-term adult health of the offspring. In this study we examined sperm and seminal plasma mediated mechanisms of preimplantation embryo development alterations in response to sub-optimal paternal diets. Male mice were fed a diet to model either under (low protein diet (LPD)) or over (high fat/sugar (Western) diet (WD)) nutrition, LPD or WD supplemented with methyl-donors or a control diet before mating with age-matched control fed females. Male metabolic health was influenced by WD and MD-WD; with significant changes in serum lipids and hepatic 1-carbon metabolites. Sperm RNA sequencing revealed significant changes to mRNA profiles in all groups when compared to CD (LPD: 32, MD-LPD: 17, WD: 53, MD-WD: 35). In vitro embryo development was revealed all sub-optimal diets with and without methyl-donors increased the rate of embryo development. As embryo development can be directed by sperm and seminal plasma mediated mechanism, we also examined the proteomic profile of the seminal plasma, revealing a significant number of changes in all groups compared to control (LPD: 13, MD-LPD: 27, WD: 24, MD-WD: 19). Male diet also altered uterine gene expression examined via qPCR, specifically alterations in Cd14 and Ptgs1 were observed in response to male WD matings. Our current study shows that paternal nutritional status has the potential to influence male metabolic and reproductive factors, which can ultimately alter embryonic development and the post-mating maternal environment. This study highlights potential direct (sperm mediated) and indirect (semen mediated) pathways in which a father's poor diet could shape the long-term health of his offspring.

Project description:Osteoarthritis (OA) is an age-related degenerative musculoskeletal disease characterised by loss of articular cartilage, synovitis, abnormal bone proliferation and subchondral bone sclerosis. The underlying pathogenesis of OA is yet to be fully elucidated with no OA specific biomarkers in clinical use. Nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) allow identification of the global metabolome and proteome respectively. During this study, ex-vivo equine cartilage explants (n=5) were incubated in TNF-α/IL-1β supplemented culture media for 8 days, with media removed and replaced at 2, 5 and 8 days. Acetonitrile metabolite extractions of 8 day cartilage explants and media samples at all time points underwent 1H NMR metabolic analysis with media samples also undergoing MS proteomic analysis. Within the cartilage, metabolites glucose and lysine were elevated following TNF-α/IL-1β treatment whilst adenosine, alanine, betaine, creatine, myo-inositol and uridine levels decreased. Within the culture media, four, four and six metabolites were identified as being differentially abundant between control and treatment groups for 1-2 day, 3-5 day and 6-8 day time points respectively. Culture media proteomics identified 154, 138 and 72 proteins differentially abundant, with > 2 fold change, between control and treatment groups for 1-2 day, 3-5 day and 6-8 day time points respectively. Nine potential novel OA neopeptides were elevated in treated media. This is the first study to use a multi ‘omics’ approach to simultaneously investigate the metabolomic profile of ex-vivo cartilage and metabolomic/proteomic profiles of culture media using the TNF-α/IL-1β ex-vivo OA cartilage model. This study has identified a panel of metabolites, proteins and extracellular matrix derived neopeptides which are differentially abundant during an early phase of the OA model which may provide further information on underlying disease pathogenesis, allow potential translation for clinical markers and possible novel therapeutic targets.
