Expression of CXCR4 and TNF-α in MKN45 and HGC27 cells after infection with H. pylori. (A) and (B) CXCR4 expression was upregulated in MKN45 and HGC27 cells after infection with H. pylori 26695 (*P < 0.01, respectively, vs H. pylori^- ) or Tx30a (*P < 0.01, respectively, vs H. pylori^- ). (C) and (D) TNF-α expression was increased in MKN45 and HGC27 cells after infection with H. pylori 26695 (*P < 0.01, respectively, vs H. pylori^- ) or Tx30a (*P < 0.01, respectively, vs H. pylori^- ). Data are expressed as mean ± SD, n = 3.
