Single Nucleotide Polymorphisms and Haplotypes of MMP-14 are Associated with the Risk and Pathological Development of Oral Cancer
摘要：
Background. Matrix metalloproteinase (MMP)-14 is one of the pericellular collagenases to degrade extracellular matrix (ECM), which is involved to the modulation of susceptibility or clinicopathological features of a cancer. The contributions of MMP-14 on the susceptibility or clinicopathological features of certain cancers have been well documented, and the expression of MMP-14 in oral squamous cell carcinoma (OSCC) also has been observed. This study was designed to examine the association of MMP-14 gene polymorphisms with the susceptibility and clinicopathological development of OSCC. Methods. A total of 363 patients with OSCC and 506 healthy control subjects were recruited. Six single nucleotide polymorphisms (SNPs) of MMP-14 genes were analyzed by polymerase chain reaction-restriction fragment length polymorphism genotyping and haplotype-base analysis. Results. MMP-14 ?7096 TC/CC genotypes might lower the risk of OSCC, and MMP-14 ?6767 GA/AA genotypes cause a poor clinical status in OSCC patients. The ?6727 C: ?6767 G: ?7096 T: ?8153 G haplotype and diplotype increased the risk for OSCC by 1.706-fold (95% confidence interval (CI) 1.383–2.105) and 2.276-fold (95% CI = 1.531–3.384), respectively, compared with the reference. The diplotype with at least one CGTG exhibited a high risk (adjusted odds ratio, 1.639; 95% CI, 1.005–2.673) for developing a poor clinicopathological diagnosis of OSCC compared with the others/other diplotype. Conclusions. The ?7096 and ?6767 polymorphic genotypes and haplotype ?6727 C: ?6767 G: ?7096 T: ?8153 G of MMP-14 gene might contribute to the prediction of susceptibility and pathological development of OSCC.
