Effect of metals and silica on TAP gene induction. BTE cells were treated with increasing doses of NiSO4 (A), Fe2(SO4)3 (B), TiO2 (C), or SiO2 (D) for 6 h, and then stimulated with or without LPS (100 ng/ml) for 18 h. mRNA was harvested and analyzed by semi-quantitative RT-PCR for TAP and normalized to GAPDH. No significance for the interaction between any of these components and LPS stimulus (ANCOVA). Experiments were carried out in triplicate. Error bars represent 1 SD.
