Tumor Cell Plasticity in Equine Papillomavirus-Positive Versus-Negative Squamous Cell Carcinoma of the Head and Neck.

Abstract: Squamous cell carcinoma of the head and neck (HNSCC) is a common malignant tumor in humans and animals. In humans, papillomavirus (PV)-induced HNSCCs have a better prognosis than papillomavirus-unrelated HNSCCs. The ability of tumor cells to switch from epithelial to mesenchymal, endothelial, or therapy-resistant stem-cell-like phenotypes promotes disease progression and metastasis. In equine HNSCC, PV-association and tumor cell phenotype switching are poorly understood. We screened 49 equine HNSCCs for equine PV (EcPV) type 2, 3 and 5 infection. Subsequently, PV-positive versus -negative lesions were analyzed for expression of selected epithelial (keratins, β-catenin), mesenchymal (vimentin), endothelial (COX-2), and stem-cell markers (CD271, CD44) by immunohistochemistry (IHC) and immunofluorescence (IF; keratins/vimentin, CD44/CD271 double-staining) to address tumor cell plasticity in relation to PV infection. Only EcPV2 PCR scored positive for 11/49 equine HNSCCs. IHC and IF from 11 EcPV2-positive and 11 EcPV2-negative tumors revealed epithelial-to-mesenchymal transition events, with vimentin-positive cells ranging between 50%. CD44- and CD271-staining disclosed the intralesional presence of infiltrative tumor cell fronts and double-positive tumor cell subsets independently of the PV infection status. Our findings are indicative of (partial) epithelial-mesenchymal transition events giving rise to hybrid epithelial/mesenchymal and stem-cell-like tumor cell phenotypes in equine HNSCCs and suggest CD44 and CD271 as potential malignancy markers that merit to be further explored in the horse.

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 study explores the cell behavior or ‘plasticity’ in horse head and neck squamous cell carcinoma (HNSCC), identifying variances between those positive and negative for equine papillomavirus infection. The findings reveal that infection status does not prevent the tumor cells from changing their phenotype in a way that could promote disease progression and metastasis.

Background of the Study

  • The research takes a focus on squamous cell carcinoma of the head and neck (HNSCC), which is a common malignant tumor in both humans and animals.
  • In humans, HNSCCs induced by papillomavirus (PV) have been observed to have a better prognosis than those unrelated to papillomavirus.
  • Crucial to the research is the concept of tumor cell plasticity, which refers to the ability of tumor cells to switch from epithelial to mesenchymal, endothelial, or therapy-resistant stem-cell-like phenotypes, a process that is understood to promote disease progression and metastasis.
  • The understanding of papillomavirus association and tumor cell phenotype switching in equine HNSCC has up until now been poorly understood.

Results of the Study

  • A total of 49 equine HNSCCs were studied for equine papillomavirus (EcPV) type 2, 3, and 5 infection. Out of these, only 11 were found to be positive for EcPV2 — the others showed no presence of equine papillomavirus types 2, 3 or 5.
  • Both EcPV2-positive and EcPV2-negative tumors were observed to experience epithelial-to-mesenchymal transition events, characterized by vimentin-positive cells ranging between less than 10% and more than 50%.
  • CD44 and CD271 staining, markers of stem cell activity, decrypted the presence of invasive tumor cell fronts and double-positive tumor cell subsets, regardless of the tumors’ papillomavirus infection status.

Interpretation and Potential Implications

  • The findings of the research suggest that (partial) epithelial-mesenchymal transition events cause the emergence of hybrid epithelial/mesenchymal and stem-cell-like tumor cell phenotypes in equine HNSCCs.
  • Interestingly, these transitions occurred irrespective of papillomavirus infection status, indicating that other factors may drive cell plasticity in this type of cancer.
  • Markers CD44 and CD271 may be potential indicators of malignancy in equine HNSCC and merit further exploration.
