Translocation of NF-κB after direct exposure of Human oesophageal squamous (HOS) cells to acidified medium. Cells were exposed to medium between pH 7.4 and pH 4 for up to 120 min and NF-κB activation scored as described in the materials and methods section. No significant NF-κB activation was detected in HOS cells exposed to pH 7.4, pH 6 or pH 5 conditions for up to 120 min. However, exposure to pH 4 resulted in significant NF-κB activation, which remained significantly higher to the end of the experiment. Results are presented as the mean ± SD of three experiments. Significant differences from pH 7.4 control are indicated by **P ≤ 0.01, *P ≤ 0.05.
