We then overexpressed IPW in DCIS.com (Fig. 2B), SUM225 (Additional file 1: Fig. S2A) and S2 (Additional file 1: Fig. S2F) cells by lentivirus-mediated transduction and studied the effect of IPW in cell growth and colony formation ability of these cells. Here, SNHG14 is linked to ductal breast carcinoma in situ.
