Among the gastric cancer-related targets, B-Cell CLL/Lymphoma 2 (BCL2)16, Caspase 3 (CASP3)17, interleukin-10 (IL-10), nitric oxide synthase, inducible (NOS2), nuclear factor kappa-B (NFκB), Cyclooxygenase 2 (COX2)18 and other proteins were involved in the immunoregulation, apoptosis and inflammatory processes of gastrointestinal diseases, which may indicate the synergistic effect of compounds and targets on gastric cancer. The gene discussed is NOS2; the disease is gastric cancer.
