Research Abstract |
We investigated anticancer activities of HP-b-CyD using BCR-ABL-induced leukemia models. We show that HP-b-CyD-mediated cholesterol efflux inhibits leukemic cell proliferation by induction of apoptosis and cell-cycle arrest. Furthermore, we found that HP-b-CyD is also effective to inhibit the proliferation of CML cells harboring the T315I mutation and stem cell-like CML cells. In vivo, systemic administration of HP-b-CyD in murine BCR-ABL-induced leukemia models suppressed leukemia progression, resulting in improved survival. Based on these novel findings, we provide evidence that HP-b-CyD is a promising anticancer agent.
