| Description | Matrix metalloproteinase (MMP) belonging to family of zinc-dependent endopeptidases participates in remodelling of extracellular matrix in many physiological and pathological processes including rheumatoid arthritis (RA). Rheumatoid arthritis is a chronic autoimmune inflammatory multi-systemic disease characterized, among others, by degradation of hyaline articular cartilage and escalated angiogenesis. As a matter of fact, these processes may by influenced by MMP. The aim of the study was to prove possible association of polymorphisms in gene promotor region for MMP-2 (-1575 G/A, -1306 C/T, -790 T/G, -735 C/T) with RA. We worked with 101 patients with RA who met reviewed diagnostic criteria of ACR (1987) for RA, and suffer from RA for at least 2 years. Control group consisted of 101 healthy volunteers of similar age and gender distribution. RESULTS: RA patients and control group did not differ in genotype distributions or frequencies of alleles of polymorphisms -1575A/G, -1306C/T and -735 C/T. Significant difference was observed between RA patients and control group in allelic frequencies of polymorphism -790 T/G MMP-2 (T allele -0.70 vs. 0.66, Pa = 0.013). Also, a tendency of GG genotype growth was noted in RA patients (Pg = 0.053). Significant difference in allelic frequencies was also observed between men with RA and men from control group (T allele -0.80 vs. 0.61, Pa = 0.025). Haplotype of GCGC polymorphisms -1575 G/A, -1306 C/T, 790 T/G, -735 C/T was more frequent in RA patients (Pcorr = 0.016; OR = 0.09; confidence interval 0.00-0.65), whereas GCTC haplotype was noted more frequently in control group (Pcorr = 0.017; OR = 1.8; confidence interval 1.17-2.70). CONCLUSION: The results indicate the association between polymorphisms in gene promotor region for MMP-2 and susceptibility to development of RA. |
