The knockdown of ABCC1 and ABCC3 reduced the expression of stemness genes (e.g., Nanog and Bmi1) in TNBC cell lines, and the knockdown of ABCC3, but not ABCC1, also reduced the CD44high/CD24low breast cancer stem-like subpopulation [104]. The gene discussed is ABCC3; the disease is breast carcinoma.
