CXCR6 expression is also positively associated with the migration of breast cancer MCF-7 and MDA-231 cells [31], gastric cancer HGC-27 cells [102], gastric cancer SGC-7901 cells [118], hepatocellular carcinoma SMMC-7721 cells [33], hepatocellular carcinoma SK-HEP-1 and HCCLM3 cells [32], osteosarcoma MG-63 cells [92], and prostate cancer PC3 and C4-2B cells [29]. This evidence concerns the gene CXCR6 and gastric cancer.
