Sažetak
Background: Retained placenta (RP), a quite common disorder in dairy cows, shows a high negative impact on their health status and milk production. Aim: To investigate the difference in the serum proteome between the cows with RP and the physiologic puerperium (PP). Material & Methods: Analysis of serum samples from nine cows with RP and six with PP using high-resolution liquid chromatography-tandem mass spectrometry approach. The proteins differing in the relative abundance between the PP and RP groups were classified using the Protein Analysis Through Evolutionary Relationship tool. For the pathway enrichment analysis, the REACTOME tool, with the human genome as the background, was employed. The criterion for significance was the false discovery rate corrected P-value less than 0.05. Results: In total 651 proteins were identified with altered relative abundance of ten proteins. Among them, seven had higher, and three showed lower relative abundance in RP than in the PP group. The differently abundant proteins participated in 15 pathways: six related to hemostasis, three involved in lipoprotein metabolism, and the remaining ones associated with for instance redox homeostasis, post- translational modification, and scavenging. Finally, the validation of the proteomic results showed that haptoglobin and lipopolysaccharidebinding protein levels reliably differentiated between the RP and PP groups. Conclusion: The pattern of serum proteome alterations in the cows with RP mirrored several interplaying mechanisms underlying the systematic response to the presence of RP, therefore representing a source to mine for predictive or prognostic biomarkers.
