This study was conducted to investigate the expression of survivin and caspase 3 in oral squamous cell carcinoma and peritumoral tissue, and possible pathogenesis mechanisms. We used ELISA and western blotting to detect the protein expression levels of survivin and caspase 3 in tissue. In situ hybridization and real-time PCR were applied to assess mRNA expression levels. In this study, 13 tumor samples and 13 peritumoral tissue samples were collected from oral squamous cell carcinoma patients and 10 normal tissue samples obtained from patients without tumor. The result showed that the protein and mRNA expression of survivin in carcinoma was the highest among three types of tissue; following was that in peritumoral tissue. No difference in caspase 3 zymogen between peritumoral tissue and normal tissue could be found, while it was evidently decreased in carcinoma tissue. Activated caspase 3 was detected in normal tissue but could not be identified in peritumoral or carcinoma tissue. Our results indicate that the expression of survivin is apparently elevated in tumoral and peritumoral tissue. Expression of activated caspase 3 was not detected in tumoral tissue and the expression of caspase 3 zymogen was decreased in tumoral tissue. Our findings suggest that survivin may inhibit both synthesis and activation of caspase 3, hence inhibiting cell apoptosis and facililitating eventual development of oral squamous cell carcinoma.
