TMPO-AS1 serves as a miR-1270’s sponge. A The putative binding regions of TMPO-AS1 in miR-1270 were predicted through the Starbase database. B SW480 cells were performed transfection with a luciferase reporter vector combined with the miR-1270 mimics for 48 h, then the luciferase activity was determined. C MiR-1270 levels in the SW480 cells knocked down of TMPO-AS1 or not. D MiR-1270 levels in the tumor and in the normal tissues were assessed via qRT-PCR. *P < 0.05, **P < 0.01, ***P < 0.001, vs. Control group.
