Abstract | INTRODUCTION AND OBJECTIVE: MATERIALS AND METHODS: We compared the frequency of single nucleotide polymorphisms in genes coding for matrix proteinases (MMP1, MMP2, MMP3, MMP9, MMP12) as well as tissue inhibitor of metalloproteinases (TIMP1) in two groups of subjects: COPD patients (54 subjects) and COPD patients diagnosed for lung cancer occurrence (53 subjects).The levels of the respective proteins in blood serum were also analyzed. RESULTS: The frequencies of 2 genotypes, MMP3 rs3025058 and MMP3 rs678815, were significantly different between the studied groups. In both cases, more heterozygotes and less homozygotes (both types) were observed in the COPD group than in the COPD + cancer group. A significantly higher TIMP1 level in blood serum was observed in the COPD + cancer group than in the COPD group. There were no statistically significant differences in MMPs blood levels between the studied groups. In addition, no genotype-associated differences in TIMP1 or MMPs blood levels were observed. CONCLUSIONS: Homozygocity for MMP3 rs3025058 and rs678815 polymorphisms is a potential marker of enhanced susceptibility to lung cancer development among COPD subjects.
