SNAI2 and breast cancer: In various cancer cell lines, miR-200b reduces EMT through direct repression of Snail1 and Snail2/Slug (Burk et al., 2008; Gregory et al., 2008; Korpal and Kang, 2008; Gill et al., 2011; Kurashige et al., 2012; Liu Y. N. et al., 2013) and, in breast cancer, miR-125b promotes EMT through modulation of Snail and E-cadherin levels (Liu Z. et al., 2013; Nie et al., 2019).
