Abstract
The present study describes two full-genome sequences of Felis catus papillomavirus type 4 (FcaPV4) identified in squamous cell carcinoma (SCC) of two domestic cats. Two full-genome sequences of FcaPV4 were detected and characterized by PCR and sequencing. The L1 nucleotide sequence homology of one case showed 95.70% sequence identity to the reference FcaPV4, suggesting that this isolate should be classified as a subtype. Reverse-transcriptase PCR (RT-PCR) of two oncogenes, E6 and E7 was performed to confirm mRNA expression. Expression of E6 and E7 mRNA was detected in both cases, suggesting that FcaPV4 contributes to the development of SCC. This is the first report of FcaPV4 subtype. The present study will update the genomic features of FcaPV4 and contribute to deepening our knowledge about the etiological roles of FcaPV4 in feline cutaneous SCC. ? 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
