Previous studies have demonstrated that miR‐338‐3p could function as a tumor suppressor in GC, NSCLC and CRC.31, 32, 33 We also confirmed the anti‐carcinogenic effect of miR‐338‐3p in CRC in this study, and the function of miR‐338‐3p is inhibited after sponged by SNHG15. Here, SNHG15 is linked to non-small cell lung carcinoma.
