Figure 5From: Involvement of tumor necrosis factor-α in the upregulation of CXCR4 expression in gastric cancer induced by Helicobacter pylori Induction of cytokines in macrophages by H. Pylori. (A) and (B) Expression of TNF-α, IL-1β and IL-6 was upregulated in 26695-treated RAW264.7 cells, *P < 0.001, vs untreated cells. (C) and (D) Neither IL-1β nor IL-6 can upregulate CXCR4 expression in MKN45 cells. Data are expressed as mean ± SD, n = 3.Back to article page
