Translation of NOTCH1 mRNA is inhibited by microRNAs miR-200B and miR-200C, which bind to the 3'UTR of NOTCH1 mRNA. Levels of miR-200B and miR-200C are decreased in pancreatic cancer cells with an EMT (epithelial to mesenchymal transition) phenotype, and the EMT phenotype is reversed by exogenous overexpression of miR-200B/C microRNAs, suggesting that miR-200B and mir-200C may be acting as tumor suppressors.
