IL-17RA signaling activates a protective pathway to prevent excessive inflammation and reduces the risk of stomach cancer (156)Tumor-associated neutrophils induce EMT by IL-17a to promote migration and invasion in GC cells (157)IL-17B signaling in IL-17RB directly promotes cancer cell survival, proliferation, and migration, and induces resistance to conventional chemotherapeutic agents (158)LCN2 Mediated by IL-17 Affects the Proliferation, Migration, Invasion and Cell Cycle of GC Cells by Targeting SLPI (159). This evidence concerns the gene SLPI and gastric neoplasm.
