ABSTRACT
Objective: To explore the expression of Dickkopf-3(DKK-3) mRNA in oral squamous cell carcinoma(OSCC) and the relationship between the promoter methylation status and the carcinogenesis of OSCC. Methods: The expression of DKK-3 gene in 51 cases of OSCC and corresponding normal mucosa tissue was detected by PT-PCR and methylation-specific PCR, respectively. The relationship between DKK-3 and the clinical pathological features of the patients was analyzed with SPSS 13. 0. Results: The expression level of DKK-3 in OSCC group was lower than that in the control(t =-12. 580, P< 0. 05). The methylation rate of DKK-3 gene promoter region in OSCC group was significantly higher than that in the control(χ2 = 19. 273, P< 0. 05). The mRNA expression level of DKK-3 gene in OSCC with methylation group was lower than that in the control(t =-2. 817, P< 0. 05). Conclusion: Down-regulation of DKK-3 gene expression and hypermethylation of promoter region are important mechanisms in the pathogenesis of OSCC. The hypermethylation of DKK-3 promoter may be the main cause of transcriptional silencing.
