Effects of Helicobacter pylori and Heat Shock Protein 70 on the Proliferation of Human Gastric Epithelial Cells
The effects of H. pylori on the proliferation of gastric epithelial cells. AGS cells were grown alone or with H. pylori (bacterium/cell ratio from 100 : 1 to 500 : 1) for 4, 8, 24, and 48 h. The proliferation of AGS cells was measured by an MTT assay. The results are expressed as absorbance at 490 nm. The data are shown as (, , and when compared with different groups, resp.).
