Figure 1E shows that LIPG was pulled down 3-fold more in the MS2-DANCR cells than the MS2 cells. The ectopic overexpression of LIPG in luminal breast cancer cell line MCF-7 (hereafter abbreviated MCF7OE) promotes migration, stemness, and basal/EMT features [7]. Similar results were observed in MCF7OE cells (Supplementary Figure S1). To determine a specific DANCR-binding region, pcDNA3-MS2-DANCRwt (1–855 bp) was deleted into DANCR1 (219–855 bp), DANCR2 (429–855 bp), and DANCR3 (639–855 bp). These constructs were transfected into MCF7OE cells (Supplementary Figure S2). Here, DANCR is linked to breast cancer.
