MYC and neoplasm: Interestingly, miR‐188‐5p and miR‐448 have 3 common targeted mRNAs; among them, USP28 is a famous oncogene that is required for MYC stability in several human tumour cells,32 while MYC is a central regulator of cell growth, proliferation and apoptosis in many human cancers.33 In the future, we will perform RIP, RNA pull‐down assays and luciferase reporter assays to verify the regulatory axes.
