Levels of IL-8 secretion and IL-8 mRNA were determined by ELISA and RT-PCR in IHOK (B) & HN12 cells (D). Same procedure as described in the legend to Fig. 1 was performed. Results are expressed as means ± SD of three independent experiments. *: Statistically significant difference compared to control group: p < 0.05, #: Statistically significant difference compared to DFO group, < 0.05
