Gastric cancer is one of the most common malignant tumors of the digestive tract, and its formation and development entail multi-stage, multi-step, and multi-factor accumulation.Tumor-suppressor genes, oncogenes, and growth factors have an important function on gastric cancer formation and development.Gastrokine 2 is a newly identified gene that is specifically expressed in stomach tissue and significantly inhibits gastric cancer cell growth.Survivin is a new member ofapoptosis protein (IAP) inhibitors, which function in inhibiting apoptosis and are closely linked to tumor progression.
