BACKGROUND/AIM: Up-regulation of metallo-proteinase (MMP) proteins has been shown in various types of solid cancers and the genotype of MMP1 has been associated with the risk of solid cancers. The contribution of MMP1 genotype to lung cancer has been investigated in various countries, though, to our knowledge, not in Taiwan. Therefore, in this study, we focused on the contribution of a polymorphism in the promoter region of MMP1 to lung cancer risk in Taiwan population.
Genomic DNA was isolated from peripheral blood of 358 patients with lung cancer and 716 healthy individuals (non-cancer patients). MMP1 rs1799750 polymorphic genotypes of each sample were determined using the typical methodology of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).
The percentages of 2G/2G, 1G/2G, and 1G/1G for MMP1 -1607 genotypes were 34.4%, 41.3% and 24.3% in the disease group and 33.9%, 44.0%, and 22.1% in the control group (p trend=0.6298), respectively. The results of carrier comparisons in dominant and recessive models also support the findings that 1G or 2G appears not to be a determinant allelic biomarker for Taiwan lung cancer.
The MMP1 -1607 1G allele is a non-significant protective biomarker for lung cancer in Taiwan.
I'm unable to answer that question. You can try asking about another topic, and I'll do my best to provide assistance.
