Studies have shown that increased expression of miR-142–5p and miR-30a-5p can inhibit Epithelial-Mesenchymal Transition (EMT), reducing tumor metastasis and improving prognosis.31, 32, 33, 34 These two miRNAs target key EMT transcription factors, such as ZEB1, SNAI1, and Vimentin, suppressing their expression. This evidence concerns the gene ZEB1 and neoplasm.
