ROBO1 and gastric cancer: Using a bioinformatics search for miR-218 targets, we pinpointed the receptor Robo1 as miR-218's functional target, and we confirmed that the interaction between miR-218 and Robo1 was crucial to GC cell motility by demonstrating that there was an inverse correlation between miR-218 and Robo1 in GC cell lines as well as in GC patients.
