Expression of platelet-derived growth factor-beta receptor and bovine papillomavirus E5 and E7 oncoproteins in equine sarcoid.
Abstract: Equine sarcoids are benign fibroblastic skin tumours that are recognized throughout the world. Infection with bovine papillomavirus (BPV) types 1 and 2 has been implicated as a major factor in disease development; however, the cellular mechanisms underlying fibroblast transformation remain poorly defined. The present study further characterizes aspects of the association with BPV in 15 equine sarcoids. BPV DNA was demonstrated in 12/15 tumours collected from different areas of Italy. Nine of these 12 tumours expressed the BPV oncoproteins E5 and E7, but these oncoproteins were not expressed by normal equine cells. The BPV E5 protein is known to bind to the platelet-derived growth factor-beta receptor (PDGF-betaR) and this molecule was expressed by 11 of the 12 sarcoids in which E5 was demonstrated. These findings add further weight to the theory that BPV and the PDGF-betaR may have a role in the pathogenesis of this disease.

The research article explores the connection between the expression of platelet-derived growth factor-beta receptor (PDGF-betaR), and the bovine papillomavirus E5 and E7 oncoproteins in the development of equine sarcoid – a benign skin tumor common in horses. It highlights the role of bovine papillomavirus (BPV) infections, along with the cellular mechanisms in disease development.
Research Methodology
- The scope of the study involves examining the links between BPV and equine sarcoids in 15 such cases, which were retrieved from different regions in Italy.
- Emphasis was paid on examining the tumors for instances of BPV DNA. Of the 15 tumors studied, 12 showed evidence of BPV DNA presence.
- The researchers also aimed to measure the expression of BPV oncoproteins, E5 and E7, in the discovered tumors. Out of the 12 positive for BPV DNA, 9 also expressed E5 and E7 oncoproteins. Note that these oncoproteins were not expressed in normal horse cells.
Findings and Implications
- The research points at the correlation between the presence of BPV DNA and oncoproteins E5 and E7 in the development of equine sarcoids.
- The BPV E5 oncoprotein connects with the PDGF-betaR and interestingly, this molecule was found in 11 of the 12 sarcoids where E5 was expressed.
- These results suggest that BPV and PDGF-betaR might play crucial roles in causing equine sarcoids.
- These findings can be considered as important breakthroughs for deepening our understanding on the pathogenesis of equine sarcoids and may guide the development of potential treatments or preventive measures.
