On the other hand, basal B-like patients express classical EMT/mesenchymal markers such as Fibronectin, the EMT inducers Twist and Slug, and the Zinc-finger transcriptional regulators Zeb1 and Zeb2 which have recently been shown to confer stemness properties that can increase the plasticity and invasive capacity of the tumour cells [54] (Fig. 5c, d). This evidence concerns the gene SNAI2 and neoplasm.
