H. pylori-induced MCP-1 mRNA expression in gastric epithelial cell lines. (A) MCP-1 mRNA profiles in various gastric epithelial cell lines (MKN45, Kato III, AGS, MKN28, MKN74) infected with H. pylori. Total RNA was isolated from uninfected (−) gastric epithelial cells or from H. pylori (ATCC 49503)-infected (+) cells and subjected to RT-PCR to evaluate steady-state MCP-1 and β-actin mRNA levels. (B) Time course of H. pylori-induced MCP-1 mRNA expression. Total RNA was extracted from MKN45 cells infected with H. pylori for the indicated time intervals and used for RT-PCR.
