title: Single-nucleotide polymorphisms and haplotypes of membrane type 1-matrix metalloproteinase in susceptibility and clinical significance of squamous cell neoplasia of uterine cervix in Taiwan women.
abstract: Membrane type 1-matrix metalloproteinase (MT1-MMP) participates in the activity of MMP-2, which correlates with cancer of uterine cervix. Single-nucleotide polymorphisms (SNPs) in promoter and exon of MT1-MMP may influence their binding with transcription factors and gene transcription. To date, no study reports the association of the MT1-MMP polymorphisms with cervical neoplasia. Therefore, we investigated the influence of the MT1-MMP gene polymorphisms on the susceptibility and clinicopathological variables of cervical neoplasia for women in Taiwan. We recruited 72 patients with cervical squamous cell carcinoma and 63 with high-grade dysplasia as 1 subgroup. Meanwhile, 280 control women were included as another subgroup. The SNPs rs1003349 (site -165), rs2236307 (+7096), and rs3751489 (+8153) as well as rs2236302 (site +6727) of MT1-MMP gene were determined by polymerase chain reaction (PCR)-restriction fragment length polymorphism and real-time PCR genotyping, respectively. Then, we correlated these SNPs and haplotypes with the development of cervical neoplasia and cancer clinicopathological variables. We found that women with CC genotype in rs2236307 SNP exhibited a more risk to develop cervical neoplasia as compared with those with wild genotype TT. Haplotypes -165 T, +6727 C, +7096 C, +8153 G or -165 G, +6727 G, +7096 T, and +8153 G and diplotypes including at least 1 type of these haplotypes of MT1-MMP gene showed a higher risk of cervical neoplasia. However, both haplotypes were not significantly correlated with the clinicopathological characteristics of cervical cancer. In conclusion, Taiwan women with variant homozygote CC (+7096) and haplotypes, TCCG and GGTG, of MT1-MMP exhibit more risk in developing cervical neoplasia.
