Abstract

Matrix metalloproteinase-2 (MMP-2) is an enzyme with proteolytic activity against matrix proteins, particularly basement membrane constituents. A single nucleotide polymorphism (SNP) at -1306, which disrupts a Sp1-type promoter site (CCACC box), displayed a strikingly lower promoter activity with the T allele. In the present study, we investigate whether this MMP-2 SNP is associated with susceptibility to breast cancer in the Saudi population. Ninety breast cancer patients and 92 age matched controls were included in this study. TaqMan Allele Discrimination assay and DNA sequencing techniques were used for genotyping. The results showed that, the frequency of MMP-2 CC wild genotype was lower in breast cancer patients when compared with healthy controls (0.65 versus 0.79). The homozygous CC (OR=2, χ(2)=5.36, p=0.02) and heterozygous CT (OR=1.98, χ(2)=4.1, p=0.04) showing significantly high risk of breast cancer in the investigated group. In conclusion our data suggest that the MMP-2 C(-1306)T polymorphism may be associated with increased breast cancer risk in the Saudi population.
