Both, IL‐6 and SDF‐1 mRNA signals have been shown to potentiate each other, thus accelerating the cytokine network in tumor tissues.64 Consistently, we have observed an increase in mRNAs for IL‐8 suggesting that both, IL‐8 and SDF‐1 could contribute to phenotypic changes observed in myofibroblasts cocultured with H. pylori. This evidence concerns the gene IL6 and neoplasm.
