Acute lymphoblastic leukemia (ALL) is a heterogeneous clonal disease originated from B- or T-cell lymphoid precursor cells. ALL is often refractory or relapses after treatment. Novel treatments are anxiously needed in order to achieve a better response and prolonged overall survival in ALL patients. In the present study, we aimed at examining the antitumor effect of niclosamide on ALL. We investigated the effects of niclosamide on the proliferation and apoptosis in vitro , the growth of ALL cells in xenografted NOD-Prkdcem26Cd52 il2rgem26Cd22 /Nju (NCG) mice. The results showed that niclosamide treatment potently inhibited the growth of ALL cells and induced apoptosis via elevating the levels of reactive oxygen species and activating TP53. These findings suggest that niclosamide may be a promisingly potential agent for ALL therapy.
