SNAI1 and neoplasm: 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.
