IGF-2-As regulates SHOX2 by adsorbing miR-503, thus affecting GC transfer; LIFR-AS1 promotes the GC advancement through miR-29a-3p/COL1A2; LINC01667 affects the proliferation of GC through miR-1385p/CyclinE1; LINC00641 initiates autophagy through miR-5825p, which affects the resistance of GC cells to oxaliplatin. Here, LIFR is linked to gastric cancer.
