BMI1 and neoplasm: Of note, the described microRNAs target not only EMT‐TFs themselves, but also genes like BMI1, CD44, CD133, JAG1, or MYC that are involved in tumor‐relevant “non‐classical” EMT functions like stemness and survival as discussed below (Brabletz & Brabletz, 2010; Brabletz et al, 2011).
