The Association of Matrix Metalloproteinase-1 Promoter Polymorphisms with Prostate Cancer in Taiwanese Patients

Abstract

Background/aim: The family of matrix metalloproteinases (MMPs) is responsible for the maintenance of extracellular matrix component homeostasis and the association of MMP-1 genetic polymorphisms with personal susceptibility to prostate cancer has only been investigated in Turkish and Japan populations and never in Taiwan. In the current study, we aimed to examine the contribution of a polymorphism in the promoter region of MMP-1 to Taiwan prostate cancer.

Materials and methods: The MMP-1 rs1799705 polymorphic genotypes were genotyped among 218 prostate cancer patients and 436 healthy controls by the typical polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodology.

Results: The percentages of 2G/2G, 1G/2G, and 1G/1G for MMP-1 -1607 genotypes were 36.2, 40.4 and 23.4% in the prostate cancer group and 33.7, 44.3, and 22.0% in the healthy control group (p trend=0.6362), respectively. The odds ratios (ORs) after adjusting for age and smoking status for those carrying 1G/2G and 1G/1G genotypes at MMP-1 -1607 were 0.84 (95%CI=0.55-1.21, p=0.3862) and 0.94 (95%CI=0.67-1.53, p=0.9586), respectively, compared to those carrying the wild-type 2G/2G genotype. Supporting these findings, the adjusted OR for those carrying the 1G allele at MMP-1 -1607 was 1.03 (95%CI=0.71-1.45, p=0.6910), compared to those carrying the wild-type 2G allele.

Conclusion: Our findings suggest that the polymorphic genotypes at MMP-1 promoter -1607 may play a major role in determining personal cancer susceptibility for prostate cancer in Taiwan.
