Qualitative analysis and functional classification of the uterine proteome of mares in oestrus and dioestrus.

Abstract: Quantitative analysis of the uterine flush fluid proteome of mares in oestrus and dioestrus has been previously reported. The objectives of this study were to: a) evaluate qualitative differences in the uterine flush fluid proteome between mares in oestrus and mares in dioestrus and b) perform a functional classification of proteins either unique to each stage or common between the two stages. Uterine flush fluid samples were collected from 8 light breed mares in either oestrus (n = 5) or dioestrus (n = 3). Proteomic analysis of the samples was conducted using liquid chromatography-tandem mass spectrometry. Proteins exclusively detected in oestrus or dioestrus and those common to both stages were identified using the Scaffold software (version 4.4.8, Proteome Software Inc., Portland, OR). The identified proteins were classified into gene ontology (GO) categories (cellular component [CC], molecular function [MF] and biological process [BP]) using the PANTHER (www.pantherdb.org) classification system version 14.0. Of 172 proteins identified, 51 and 28 were exclusively detected in mares in oestrus and dioestrus, respectively, and 93 proteins were common to both stages. The most represented terms in various GO categories were similar among the three subsets of proteins. The most represented CC terms were extracellular region and cell, the most represented MF terms were catalytic activity and binding, and the most represented BP terms were metabolic process and cellular process. In conclusion, proteomic analysis of the uterine flush fluid enabled the identification of subsets of proteins unique to oestrus or dioestrus, or common to both stages. The results of this study can serve as a baseline for future research focused on finding stage-specific protein markers or evaluating differences in the uterine flush fluid proteome between normal mares and those with uterine disease.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This research article investigates the differences and similarities in the protein makeup found in a mare’s uterine fluid during two reproductive stages, oestrus and dioestrus. The aim is to catalogue these proteins for future studies related to equine uterine health and potential disease markers.

Research Objectives

The main objectives of this study were to:

  • Evaluate qualitative differences in the uterine flush fluid proteome (the set of proteins found in the fluid) between mares in oestrus (a stage when mares are sexually receptive) and mares in dioestrus (the stage immediately following oestrus).
  • Classify the proteins unique to each stage and those common to both stages.

Methodology

Eight light breed mare uterine fluid samples were collected and analyzed using liquid chromatography-tandem mass spectrometry, which is a sophisticated technique for identifying and quantifying proteins within a sample. The researchers used software to identify proteins that were exclusively present in mares in either the oestrus or the dioestrus stage, as well as proteins that were common in both stages.

Findings

The researchers identified:

  • 172 total proteins in the uterine fluid samples.
  • 51 proteins were unique to mares in the oestrus stage.
  • 28 proteins were unique to mares in the dioestrus stage.
  • 93 proteins were common to both stages.

Importantly, the proteins were further classified into gene ontology (GO) categories involving cellular components, molecular function and biological processes. The classifications provided patterns in the subsets of proteins, suggesting their role in the horse’s reproductive cycle.

Conclusion

The findings in this study have offered a significant foundation for future research. Identifying stage-specific protein markers and evaluating differences in the uterine flush fluid proteome between normal mares and those with uterine disease could greatly aid in the understanding and treatment of equine reproductive health.
