Searching for serum protein markers of equine squamous gastric disease using gel electrophoresis and mass spectrometry.
Abstract: Equine squamous gastric disease (ESGD) is a very common disorder but an accurate and practical screening technique for detecting ESGD is currently lacking. Objective: To identify serum protein markers to detect ESGD using electrophoresis and mass spectrometry. Methods: Proteomic analysis and bioinformatics. Methods: ESGD was diagnosed using gastroscopy in 30 horses. Gastric ulceration was categorised into three groups: normal, mild/moderate and severe ESGD. Pooled sera from each group were compared using 1D electrophoresis and mass spectrometry. The candidate proteins for ESGD markers were selected based on their specifically high expression in nonglandular stomach, and their association with gastric ulceration using public gene and protein databases. Results: The prevalence of ESGD in this study was 43% (with mild/moderate ESGD at 33% and severe ESGD at 10%). The proteomic study revealed that the identified serum protein markers for normal equine stomach were B4GALNT2 and XDH. The marker for mild/moderate EGSD was KRT10, while the marker for severe ESGD was KLK13. Furthermore, markers for both ulcer types were SLC4A7, PPARG, FCGBP, PKP1, ASPRV1 and KRT5-like proteins. Conclusions: The functions of the identified proteins are not well characterised in horse. Proteomics is a tool for screening protein markers, but confirmation of putative protein markers with specific antibodies is required. Conclusions: In total, 10 serum proteins found in this study may be used as putative markers for ESGD. However, confirmation of candidate proteins with specific antibodies in a larger study cohort is necessary before it can be used in the veterinary clinic or on horse farms.

This research paper is focused on identifying serum protein markers for equine squamous gastric disease (ESGD) using electrophoresis and mass spectrometry techniques.
Objective of the Study
The objective of this research was to identify serum protein markers for ESGD, a very common disorder in horses. Despite its prevalence, a practical and accurate screening method for ESGD is currently missing. The researchers employed gel electrophoresis and mass spectrometry techniques in an effort to fill this gap.
Methods Used
- Diagnosis of ESGD was performed using gastroscopy in 30 horses and the existence of gastric ulceration was categorized into three groups: normal, mild/moderate, and severe ESGD.
- The researchers pooled sera from each category and compared them using one-dimensional (1D) electrophoresis and mass spectrometry.
- The selection of protein markers for ESGD was based on proteins that were highly expressed in the non-glandular stomach and those associated with gastric ulceration as per public gene and protein databases.
Key Findings
- The study revealed a prevalence of 43% ESGD, where 33% of cases were mild/moderate in nature and 10% were severe.
- The protein markers identified for a normal equine stomach were B4GALNT2 and XDH, while KRT10 was noted as a marker for mild/moderate ESGD, and KLK13 for severe ESGD.
- In both ulcer types, the markers SLC4A7, PPARG, FCGBP, PKP1, ASPRV1, and KRT5-like proteins were identified.
Conclusions
- The specific functions of these proteins in the horse are not yet completely understood.
- Proteomics proves a useful tool in the search for protein markers,but these putative markers require further verification with specific antibodies for confirmation.
- A total of 10 serum proteins were proposed as markers for ESGD from this study, but before these can be applied in a veterinary clinic or on horse farms, a larger study cohort is needed for validation with specific antibodies.
