Effects of resistin on inflammatory response in myocytes and peripheral blood mononuclear cells (PBMC). Expression of IL-1α (a), IL-6 (b), MCP-1 (c) and TNFα (d) mRNA levels after stimulation with human resistin (10, 100, 1,000 ng/ml) for six hours in myocytes and PBMC. Data are shown as fold changes compared to unstimulated controls (in graphs represented by control bar, rated as 1). Bars represent the mean + SEM. P-values less than 0.05 were considered statistically significant; * P < 0.05, ** P < 0.01.
