Compared to adjacent non-cancerous tissues or normal tissue, the expression of CXCL16 within tumors is elevated, for example in colon cancer [171], colorectal cancer [153,172], gastrointestinal stromal tumors [107], gastric carcinomas [173], glioblastoma multiforme [99,134,174], lung cancer [28], nasopharyngeal carcinoma [148], osteosarcoma [89], ovarian cancer [27,113,128], pancreatic ductal adenocarcinoma [87,106], papillary thyroid cancer [90,145], prostate cancer [116,175], and schwannomas [101]. Here, CXCL16 is linked to colonic neoplasm.
