Abstract

Background and Purpose: Arecoline, an areca quid (AQ) component, has been shown to inhibit the secretion and activity of matrix metalloproteinase-2 (MMP-2) in fibroblast cultures. This study assessed whether MMP-2 expression was inhibited in the saliva samples and tumor specimens of oral tumor patients with a long-term history of AQ consumption. The net effect of crude AQ extract (AQE) on MMP-2 expression by oral cells was also investigated. Methods: Western blot analysis, zymography, and reverse transcriptase-polymerase chain reaction were used to detect MMP-2 protein and mRNA in saliva and tumor samples, as well as in the conditioned media (CM) of oral cell cultures. Results: The level of MMP-2 protein was significantly higher in the saliva samples of 12 oral tumor patients who had a minimum 10-year AQ-consuming history than in those of 12 non-AQ-using healthy controls (p <0.05). MMP-2 mRNA was expressed in 26 of 28 oral squamous cell carcinoma (OSCC) specimens. MMP-2 protein was also detectable in the tested OSC-C homogenates. Short-term stimulation with 10% AQE increased the secretion of MMP-2 protein in the CM of oral epidermoid carcinoma cell Meng-1 (an OSCC cell line) and oral fibroblasts. Conclusions: MMP-2 expression is elevated rather than inhibited in most oral tumor patients with long-term AQ usage. Short-term AQE stimulation also increases the secretion of MMP-2 by oral epithelial cells and fibroblasts. Our results suggest that AQ consumption may promote oral tumor progression through the induction of MMP-2 secretion.
