Abstract:
BACKGROUND AND OBJECTIVES: The matrix metalloproteinases (MMPs) have been associated with tumor cell invasion and metastasis by mediating the degradation of extracellular matrix components. Cyclooxygenase-2 (COX-2) plays an important role in promotion of carcinogenesis, tumor invasiveness and angiogenesis. Recently, some investigators have reported that COX-2 could promote secretion of MMP-2 and MMP-9. Therefore, an interrelation between MMPs and the associated COX-2 may play a significant role in the invasive phenotype of malignant tumors. In the present study, the authors investigated the correlation between expressions of COX-2 and MMPs. MATERIALS AND METHOD: Immunohistochemical staining of MMP-2, -3 and -9, and COX-2 were performed on paraffin-embedded tissue sections of 51 nasal cavity and paranasal sinuses tumors (27 inverted papillomas, 5 inverted papillomas with malignant transformation, and 19 squamous cell carcinomas). Co-expression of these MMPs and COX-2 was visualized with confocal laser scanning microscope. RESULTS: MMP-2, -3 and -9 were found mainly in malignant lesions in concert with COX-2. However, the co-expressions of MMP-2 and COX-2, MMP-9 and COX-2 were detected with significance. CONCLUSION: These results suggest a potentially important role for COX-2 in the regulation of MMPs, malignant transformation, and progression of squamous cell carcinoma, and it points out the potential use of COX-2 inhibitors, in the prevention and treatment of squamous cell carcinoma of nasal cavity and paranasal sinuses.
