title: [Association of functional polymorphisms on MMP-12 and MMP-13 gene promoter region with epithelial ovarian carcinoma].
abstract: OBJECTIVE
  To investigate whether the functional polymorphisms in the promoter region of MMP-12 (-82A/G) and MMP-13(-77A/G) are associated with epithelial ovarian carcinoma (EOC).
  
  
  METHODS
  The MMP-12 -82A/G and MMP-13 -77A/G were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 300 epithelial ovarian carcinoma patients and 300 control women.
  
  
  RESULTS
  The A/G genotype frequency of the MMP-12 gene was significantly higher in the patients than in the controls (P= 0.003); similarly, the frequency of MMP-12 -82G allele was higher in the patient group (P= 0.004). Compared with the A/A genotype, the A/G genotype carriers significantly increased the risk of EOC development (OR= 2.81, 95%CI: 1.38-5.74). No overall association between the MMP-13 -77A/G polymorphism and EOC(P= 0.15) was observed. However, the A/A genotype carriers in the MMP-13 -77A/G locus had significantly higher risk of developing serous-papillary and mucinous ovarian cancer (OR= 1.93, 95% CI: 1.05-3.53; OR= 5.16, 95% CI: 1.62-16.44, respectively), comparing with the G/G genotype carriers. Combining the two SNPs, the haplotype distributions in patients were not significantly different from that in control women (P= 0.06).
  
  
  CONCLUSIONS
  These results suggested that individuals with MMP-12 -82A/G and MMP-13 -77A/A might have higher risk of overall or special histological type of EOC development.
