To investigate the underlying mechanisms of OIP5-AS1 in the development of GC, starbase, RMBase V2.0, RM2Target and POSTAR3 were used to predict the targets of OIP5-AS1, and found that IGF2BP3 and YTHDC1 that bind to OIP5-AS1 (Supplementary Fig. 2A). This evidence concerns the gene YTHDC1 and gastric cancer.
