mRNA expression levels of antioxidant systems. Quantification of mRNA expression levels for HO-1 (panel a and d), SOD-2 (panel b and e) and GPX-1 (panel c and f) in RAW 264.7 macrophages exposed to 0.1-50 μg/mL of S- and L-CNT for 6 (panel a-c) or 24 (panel d-f) hours. *: p<0.05 versus control condition. C: Control (unexposed) cells. S-CNT: short CNT. L-CNT: long CNT.
