• Although increasing long noncoding RNAs (lncRNAs) have been identified by high‐throughput sequencing, their functions in human cancer remain largely unknown. The function of lncRNA miR143HG has not been explored before. In the present study, we found that miR143HG expression was significantly downregulated in bladder cancer tissues (BCa) compared with normal tissues. We showed that miR143HG high expression was associated with a high survival rate in BCa patients. Gain‐of‐function assays demonstrated that miR143HG overexpression suppressed the proliferation, arrested cell cycle progression, and attenuated migration and invasion of BCa cells in vitro. In vivo assay illustrated that ectopic expression of miR143HG inhibited BCa growth in vivo. Mechanistically, miR143HG was identified to inhibit the level of miR‐1275, whereas miR‐1275 directly targeted AXIN2, a negative regulator of the Wnt/β‐catenin pathway. Restoration of miR‐1275 or knockdown of AXIN2 significantly rescued the proliferation, migration, and invasion abilities of BCa cells. In summary, our findings demonstrated that miR143HG/miR‐1275/AXIN2 axis regulates BCa development by modulating the Wnt/β‐catenin pathway. Our findings demonstrated that miR143HG/miR‐1275/AXIN2 axis regulates bladder cancer tissue development by modulating Wnt/β‐catenin pathway.
