IL6 and gastric cancer: In addition, one such study demonstrated that omental tissue-derived exosomes of gastric cancer patients shuttle higher levels of interleukin-6 (IL-6), interleukin-8 (IL-8), intercellular adhesion molecule-1 (ICAM-1), growth related oncogene (GRO), basic fibroblast growth factor (bFGF), adiponectin, and C-C Motif Chemokine Ligand (CCL4) (45), which had been studied as GC-related cytokines facilitating gastric cancer proliferation, angiogenesis, invasion, immunomodulation, and peritoneal metastasis (46–48).
