Proliferation of HSP70-silenced AGS line exposed to H. pylori. The HSP70-silenced AGS line (siHSP70-stably transfected-AGS cells) and control cells (siControl-stably transfected-AGS cells) were cocultured with H. pylori (bacteria : epithelial cell ratio 200 : 1) for the indicated times. Then, cell proliferation was detected by an MTT assay as described above. The results were expressed as absorbance. The data was shown as means ± SD (*P < 0.05, when compared with the control group).
