Ox-LDL induced inflammatory cytokine expression in RAW264.7 cells. The expression of inflammatory cytokines, (A) TNF-α, (B) IL-6 and (C) IL-1β, in RAW264.7 cells following incubation with various concentrations (0, 50 and 100 mg/l) of ox-LDL for 24 h. The cytokine concentrations were quantified by ELISA. Data are presented as the mean ± standard error of the mean from three independent experiments. *P<0.05 as indicated. TNF-α, tumor necrosis factor-α; IL, interleukin; Ox-LDL, oxidized low-density lipoprotein.
