  • Title: Functional polymorphisms in matrix metalloproteinase-1 and monocyte chemoattractant protein-1 and rheumatoid arthritis.
    Author: Lee YH, Kim HJ, Rho YH, Choi SJ, Ji JD, Song GG.
    Journal: Scand J Rheumatol; 2003; 32(4):235-9. PubMed ID: 14626631.
    Abstract:
    The aim of this study is to investigate whether the functional polymorphisms in the promoter of matrix metalloproteinase-1 (MMP-1) and in the regulatory region of the monocyte chemoattractant protein-1 (MCP-1) gene are associated with susceptibility to rheumatoid arthritis (RA) and its clinical features. The MMP-1 1G/2G polymorphism and the MCP-1 promoter A/G polymorphism were determined by polymerase chain reaction-restriction fragment length polymorphism in 117 RA patients and 97 healthy controls. The genotype distribution of the MMP-1 promoter did not differ between RA patients and control subjects. However, in the 2G/2G genotype, ESR and Plat were higher than the 1G/1G genotype. The genotype distribution of the MCP-1 promoter did not differ between the RA and control groups. Clinically there was no significant difference among RA patients according to the MCP-1 promoter genotypes. Our data show that the functional promoter polymorphism in the MMP-1 promoter may not play an important role in the susceptibility of RA, but the polymorphism may be related to clinical phenotypes.
