Localization of Felis catus Papillomavirus Type 2 E6 and E7 RNA in Feline Cutaneous Squamous Cell Carcinoma.

ABSTRACT: Findings from polymerase chain reaction-based methods have suggested a role of Felis catus papillomavirus 2 (FcaPV-2) in the development of feline cutaneous squamous cell carcinoma (SCC). However, because polymerase chain reaction cannot localize deoxyribonucleic acid or ribonucleic acid within the lesion, it is difficult to differentiate a coincidental FcaPV-2 infection and a causative association. Given that a key event in the pathogenesis of human papillomavirus-induced cancer is the expression of viral E6 and E7 oncogenes, localization of FcaPV-2 E6 and E7 transcription within neoplastic cells in feline SCCs would support a causative role for this papillomavirus. Therefore, RNAscope in situ hybridization was used to localize FcaPV-2 E6 and E7 transcripts in 18 formalin-fixed paraffin-e
