Drug resistance to TKIs and the existance of CML leukemia stem cells is an urgent problem. In this study, we demonstrate that quinacrine (QC) induces apoptosis in BCR-ABL positive CML and acute lymphoblastic leukemia (ALL) cells. Interestingly, QC inhibits the colony formation of primary CD34(+) progenitor/stem leukemia cells from CML patients. QC targets RNA polymerase I, which produces ribosomal (r)RNA, involving in protein translation process. Also, QC treatment prolongs CML-like mice survival and inhibits K562 tumor growth in vivo. In conclusion, we demonstrate that QC depletes BCR-ABL protein and suppresses Ph-positive leukemia cells in vitro and in vivo.
