Figure 4. miR-424-5p targeted WIF1. (A) The downstream molecules of miR-424-5p were predicted by StarBase database (https://web.archive.org/web/20110222111721/http://starbase.sysu.edu.cn/), and miR-424-5p was found to be the target of WIF1. (B) The binding association between miR-424-5p and WIF1 was testified by dual-luciferase reporter assay. (C) RIP was conducted to determine the targeting correlation between miR-424-5p and WIF1. (D) IP was applied to examine the association between WIF1 and Wnt. (E, F) MiR-424-5p and WIF1 levels were tested by qRT-PCR.
