FGF18, a ligand for FGFR2, interacts with FGFR2, enhances F‐actin, and then promotes nuclear aggregation of YAP1; FGFR2 also activates the MAPK pathway and its downstream molecule, c‐Jun, which upregulates YAP1 transcription to promote the progression of gastric cancer.216. This evidence concerns the gene YAP1 and gastric cancer.
