Abstract

Objective: Matrix metalloproteinase 1 (MMP1) plays an important role in the development of lung cancer. This study was to investigate the relation to associate the single nucleotide polymorphism(SNP)in MMP1 gene with the susceptibility to lung cancer in Northwestern Chinese population of Han nationality.

Methods: By using the methods of polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP), MMP1 -1607(1G>2G) polymorphisms in 150 patients with lung cancer, and 200 healthy controls were detected to evaluate the relationship between different genotypes and susceptibility of lung cancer.

Results: Individuals with 2G/2G genotype had 1.77 fold risk suffering from lung cancer, when compared with ones with 1G/2G and 1G/1G genotypes. Smokers with 2G/2G genotype exhibited 3.20 fold elevated risk for lung cancer (OR 3.20; 95% CI 1.50-6.82).

Conclusion: The -1607(1G>2G) in promoter region of MMP1 is associated with susceptibility to lung cancer in Northwestern Chinese population of Han nationality. The genotype 2G/2G enhances the susceptibility to lung cancer.
