Plasma protein changes in horse after prolonged physical exercise: a proteomic study.
Abstract: Physical exercise induces various stress responses and metabolic adaptations that have not yet been completely elucidated. Novel biomarkers are needed in sport veterinary medicine to monitor training levels and to detect subclinical conditions that can develop into exercise-related diseases. In this study, protein modifications in horse plasma induced by prolonged, aerobic physical exercise were investigated by using a proteomic approach based on 2-DE and combined mass spectrometry procedures. Thirty-eight protein spots, associated with expression products of 13 genes, showed significant quantitative changes; spots identified as membrane Cu amine oxidase, α-1 antitrypsin, α-1 antitrypsin-related protein, caeruloplasmin, α-2 macroglobulin and complement factor C4 were augmented in relative abundance after the race, while haptoglobin β chain, apolipoprotein A-I, transthyretin, retinol binding protein 4, fibrinogen γ chain, complement factor B and albumin fragments were reduced. These results indicate that prolonged physical exercise affects plasma proteins involved in pathways related to inflammation, coagulation, immune modulation, oxidant/antioxidant activity and cellular and vascular damage, with consequent effects on whole horse metabolism.

This research investigates the changes in protein structures in horse plasma following extensive aerobic exercise. It provides valuable insights into potential biomarkers to monitor training levels and detect diseases in sport horses.
Research Purpose
The primary purpose of the study was to identify changes in protein structures in horse plasma induced by prolonged, aerobic physical exercise. It aimed to contribute to the understanding of physiological responses and metabolic adaptations after extended physical exertion. The research could lead to the identification of novel biomarkers used to monitor training intensities and detect underlying health conditions potentially progressing into exercise-related diseases.
Methodology
The research utilizes proteomic approach, utilizing techniques such as:
- Two-Dimensional Gel Electrophoresis (2-DE): This is an advanced procedure in which a complex mixture of proteins is separated into individual proteins based on two distinct properties – isoelectric point and molecular weight.
- Mass Spectrometry: It’s an analytical technique used to measure the mass-to-charge ratio of ions, facilitating the identification and structural characterisation of molecules.
Results
The study observed significant quantitative changes in 38 protein spots notably associated with the expression products of 13 genes. Some proteins increased in relative abundance following the exercise, including:
- Membrane Cu amine oxidase,
- α-1 antitrypsin,
- α-1 antitrypsin-related protein,
- Caeruloplasmin,
- α-2 macroglobulin,
- Complement factor C4.
Conversely, some proteins were found reduced after the physical activity:
- Haptoglobin β chain,
- Apolipoprotein A-I,
- Transthyretin,
- Retinol binding protein 4,
- Fibrinogen γ chain,
- Complement factor B,
- Albumin fragments.
Implications
These results suggest that prolonged physical exercise impacts plasma proteins involved in inflammation, coagulation, immune modulation, oxidant/antioxidant activity and cellular and vascular damage pathways, consequently affecting the overall horse metabolism. This research can significantly improve monitoring and disease detection in sport horses, highlighting the value of proteomic studies in veterinary and exercise science.
