The effect of niacin on IL-6 (A) and PDG2 (B) release by RAW264.7 cells treated with LPS. RAW264.7 cells stimulated by LPS were exposed to niacin at different concentrations overnight. The medium was collected for IL-6 and PDG2 measurement. Results shown are the mean ± SD of quadruplicate measurements from one representative experiment out of three performed (*p < 0.05; **p < 0.01, ***p < 0.001, compared with the control groups).
