Figure 2: Upregulation of the inflammatory cytokine tumor necrosis factor alpha (TNF-α) and mucin gene (MUC5AC) expression in HMEECs exposed to FA. (a) The expression of mRNA encoding TNF-α was upregulated in cells treated with 2 mM FA for 4 h and 0.2 mM FA for 24 h. (b) The expression of mRNA encoding MUC5AC was upregulated in cells treated with 0.2 mM FA for 24 h. Error bars represent SD of the mean. Data represent the means ± SD from three repeated experiments with triplicate samples. compared with the control values.
