COX-1 and COX-2 Expression in Feline Oral Squamous Cell Carcinoma
چکیده انگلیسی

SummaryThis study demonstrated immunohistochemically the expression of cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) in feline oral squamous cell carcinoma (FOSCC), with primary polyclonal antibodies raised against human epitopes. COX-2 immunolabelling was intracytoplasmic and, in some neoplastic cells, perinuclear; it was demonstrated in a small proportion (⩽1%) of neoplastic cells and its intensity was usually mild to moderate. In contrast, all neoplastic tissues showed extensive nuclear and cytoplasmic COX-1 immunolabelling. Cytoplasmic COX-1 immunolabelling was less intense than nuclear labelling in neoplastic tissue. In the adjacent histologically normal oral mucosa, COX-2 immunolabelling was absent. The cytoplasmic and nuclear intensity and distribution of COX-1 immunolabelling was significantly higher in neoplastic tissue than in adjacent normal oral mucosa. The results indicate that COX-1 and COX-2 are overexpressed in FOSCC, but the clinical and pathophysiological significance of this finding remains to be determined.
