Arthritic K/BxN mice were bred from non-arthritic C57B6/Ag7 females and KRN males to evaluate bioactive lipid mediators (BLM) in murine inflammatory arthritis. All mice were maintained on a standard mouse chow diet until sacrifice at 9 weeks (n = 10; 5 M/5F), 14 weeks (n = 12; 6 M/6F), and 21 weeks (n = 7; 2 M/5F) [arthritic K/BxN mice = 29] and 14 weeks KRN (n = 10; 5 M/5F) and C57Bl/6-Ag7 (n = 10; 5 M/6F), [non-arthritic controls = 21]. 16 RA patients with atherosclerotic plaque identified on carotid ultrasound were also compared to 16 matched RA patients without plaque and 16 non-RA healthy controls. Mouse and human RA groups were compared to controls as described in the “Materials and methods”. (A) PON1 activities. (B) Bioactive lipid mediators (BLM). (C) Correlations of BLM with PON1 activities.
