Association of IL-6, IL-8, MMP-13 gene polymorphisms with knee osteoarthritis susceptibility in the Chinese Han population.

ABSTRACT: Objective: To identify the association between the interleukin (IL) 6 (IL-6) rs1800795 (-174 G>C), IL-8 rs4073 (-251T>A), and matrix metalloproteinase-13 (MMP-13) rs2252070 (-77G>A) gene polymorphisms and knee osteoarthritis (KOA) susceptibility in the Chinese Han population. Methods: Genomic DNA was extracted from a total of 400 KOA patients and 400 healthy subjects. Sanger sequencing was performed to determine the genotypes of the IL-6 rs1800795 (-174 G/C), IL-8 rs4073 (-251A/T), and MMP-13 rs2252070 (-77A/G) loci. The mRNA expression levels of IL-6, IL-8, and MMP-13 in osteoblasts and the protein expression levels of IL-6, IL-8, and MMP-13 in the synovial fluids of KOA patients were analyzed. Results: The recessive model of IL-6 rs1800795 locus was found to be associated with KOA risk (
