To assess whether DANCR regulates EMT or cancer stemness of malignant breast cancer cells, we first examined the expressions of EMT‐related biomarkers, including SNAIL1, SLUG, MMP‐2, MMP‐9, E‐cadherin, and Vimentin in shDANCR vs. shNC (MDA‐MB‐231 and MDA‐MB‐468) cells. Here, DANCR is linked to breast carcinoma.
