These effects are associated with the induction of IL-6 and CXCL8, two cytokines known to enhance tumor progression and to be also produced in other tumor contexts, including such as ovarian, prostate and breast cancers, as well as hepatocellular, esophageal and gastric carcinoma [38, 39, 40]. This evidence concerns the gene CXCL8 and gastric carcinoma.
