Quantitative PCR analysis for the expression of pro-inflammatory markers such as IL-1β, IL-8, iNOS and COX2 in cells cultured in presence of 10 (a, c, e, g) or 100 ng/ml LPS (b, d, f, h). Expression levels normalized to the reference gene GAPDH. Data are represented as fold-change compared with expression observed in untreated cells. Values are mean ± SD (n = 3). Asterisk depict highly significant (*, P < 0.01) differences compared to untreated cells
