In previous studies, ∼60% of the analysed feline skin SCCs did not stain for p5334,35, consistently, at least in part, with our data; in the remaining ∼40% of positive samples, the staining was restricted to the nuclei, however p53 expression and staining pattern have never been correlated with FcaPV-2 oncogenes expression. The gene discussed is TP53; the disease is neoplasm.
