Expression of ADAM-17 in RA serum and SFs. a ADAM-17 is higher in RA serum than OA and NL serum. b ADAM-17 expression is also higher in RA SFs than OA SFs. c The level of ADAM-17 in RA serum is correlated with disease activity. (n = number of patients). ADAM a disintegrin and metalloprotease family protein, DAS28 disease activity score 28, ESR erythrocyte sedimentation rate, NL normal, OA osteoarthritis, RA rheumatoid arthritis
