Further exploring the molecular mechanism by which miR-203 affects SRC, SNAI2, and KIF2A expression in tumor cells, we identified predicted miR-203-binding sites in the 3′UTR regions of the SRC, SNAI2, and KIF2A mRNA transcripts (Figure 4B), suggesting that SRC, SNAI2, and KIF2A mRNAs are putative miR-203 targets. This evidence concerns the gene SNAI2 and neoplasm.
