Synovial fibroblasts from obese OA patients secrete more IL-6 than cells from normal weight patients. (A) Secretion of IL-6 at baseline from normal weight (n = 4) and obese synovial fibroblasts (n = 4), as measured by ELISA. Data are mean ± SEM *p < 0.05. (B) mRNA expression of IL-6ST (gp130) and IL-6 as determined by quantitative real-time PCR. Data are mean ± SEM (normal weight n = 6; obese n = 12). Statistical significance was determined by Mann-Whitney U test where *p < 0.05, and ***p < 0.001.
