NRAS and gastric cancer: It has been suggested that regulatory networks of hsa_circ_0050102–hsa-miR-4537–NRAS–Tgd cells and hsa_circ_0003763–hsa-miR-145-5p–FGF10–StromaScore may play important roles in the proliferation, migration, and invasion of GC by involving signaling pathways of Rap1 and Ras.
