The Wnt signaling pathway has been identified for its function in carcinogenesis and embryonic development. It is known to play a vital role in the initiation and development of colorectal cancer (CRC). Therefore, it is of great importance for CRC research to illuminate the mechanisms which regulate Wnt pathway activity. Here, we intended to examine the effect of hsa-miR-942 (miR-942) on the Wnt signaling activity, cell cycle progression, and its expression in CRC tissues. RT-qPCR results indicated that miR-942 is significantly upregulated in colorectal cancer. Then, overexpression of miR-942 promoted, whereas its inhibition decreased the Wnt signaling activity, detected by RT-qPCR and Top/Fop flash assay. Inhibition of Wnt signaling by using PNU-74654 or IWP-2 small molecules indicated that miR-942 applies its effect to the β-catenin degradation complex level. Then, RT-qPCR and dual luciferase assay …
