The miR‐200 family was found to act as a tumor‐suppressive group of miRNAs that targets ZEB1, ZEB2, and Slug genes, which drive epithelial–mesenchymal-transition and tumor progression in prostate cancer cells (Mongroo and Rustgi, 2010; Liu et al., 2013; Feng et al., 2014). This evidence concerns the gene SNAI2 and neoplasm.
