Influence of matrix metalloproteinase-1 gene -1607 (1G/2G) (rs1799750) promoter polymorphism on circulating levels of MMP-1 in chronic pancreatitis.

This study investigated the role of -1607 (1G/2G) (rs1799750) polymorphism of the MMP-1 gene in chronic pancreatitis. We genotyped 100 patients with chronic pancreatitis and 100 control subjects using tetra-primer ARMS-PCR followed by agarose gel electrophoresis. Serum levels of MMP-1 were determined by Elisa. Statistical analysis was applied to test the significance of the results. The genotypic and allelic distribution varied significantly between the disease group and the control subjects [OD = 1.981 (1.236-3.181), p = 0.004]. MMP-1 levels were higher in subjects homozygous for the 2G allele than in subjects with the 1G allele. The present study revealed a significant association of the MMP-1 -1607 1G/2G (rs1799750) gene promoter polymorphism with chronic pancreatitis, and it can be considered a biological marker in the etiology of chronic pancreatitis.
