Blocking the IL-6 receptor (IL-6R) or IL-8 receptor (CXCR1) reduces the adhesion of ovarian cancer cells to the omentum, a fat-rich tissue primarily composed of adipocytes, and reduces the migration of ovarian cancer cells to primary adipocytes in vitro, indicating that the metabolic cooperation between cancer cells and adipocytes is mediated by adipokine signalling molecules [14]. This evidence concerns the gene IL6R and cancer.
