Furthermore, DANCR‐expressing cells generated larger (Fig. 6C) and more mammospheres (Fig. 6D), which corresponded to the elevations of CSC biomarkersg CD44, CD133, OCT3/4, and NANOG (on both mRNA and protein levels; P < 0.05, when compared with vector cells; Fig. 6E–H), suggesting the potency of DANCR in promoting EMT and cancer stemness in normal breast epithelial cells or breast cancer cells of low malignancy. Here, CD44 is linked to breast carcinoma.
