Direct and indirect quartz effects on iNOS, COX-2 and HO-1 mRNA expression in RLE cells. Quantitative RT-PCR determination of mRNA levels of iNOS (A), COX-2 (B) and HO-1 (C) in RLE cells after treatment with quartz (Q) and supernatants of quartz-treated macrophages (Q-MS) for 2, 4 or 8 h. As an extra control, cells were additionally treated with supernatants of non-treated macrophages (c-MS). Data are expressed as fold increase of mRNA levels in non-treated control cells and were corrected for the housekeeping gene β-actin. *P < 0.05 and **P < 0.01 vs. control.
