Based on the role of miRNAs in tumour development and the regulation of mRNAs [42], we used bioinformatics databases, including miRwalk, miRdb and TargetScan (Supplementary Table 2), to predict the upstream miRNAs that may regulate NEDD9, and we selected miR-103a-3p and miR-107 as candidates. This evidence concerns the gene NEDD9 and neoplasm.
