To elucidate whether MYEOV transcript operates as a ceRNA for miR-30c-2-3p in NSCLC progression, in vivo gain-of-function studies were performed by overexpressing wild-type full-length MYEOV cDNA (MYEOV-cDNA), MYEOV cDNA carrying mutation in the in-frame start codon (MYEOV-ATGmut), and MYEOV with mutation of all five predicted miR-30c-2-3p binding sites (MYEOV-miRmut), respectively, in A549, which expresses low-level endogenous MYEOV transcript (Fig. 3a and Supplementary Figure S5a). Here, MYEOV is linked to non-small cell lung carcinoma.
