Forced expression of hnRNPA1 partially rescued the OIP5-AS1 knockdown-mediated inhibition of GC cell growth, migration, and invasion (Figs. 9B–G, 10A, B) whereas inhibition of hnRNPA1 partially reversed the GC cell growth and metastasis promoting effects induced by OIP5-AS1 upregulation (Figs. 11B–G, 12A, B). This evidence concerns the gene PTGDR and gastric cancer.
