In cancer, cadherin-17 expression reportedly correlates with clinical association with tumor metastasis and advanced tumor stages in hepatocellular carcinoma [9], knockdown of cadherin-17 inhibited cell proliferation, adhesion, migration, and invasion in gastric cancer [10], and an anti-cadherin-17 antibody suppresses subcutaneous hepatocellular carcinoma growth and lung metastasis [11]. This evidence concerns the gene CDH17 and cancer.
