Multiple myeloma (MM) is a malignancy of the bone marrow. The median survival time of patients with MM is only 5 years, with patients frequently experiencing relapse. Currently, there is no effective therapy for recurrent MM. The results of the present study indicated that pyrvinium pamoate (PP), a US Food and Drug Administration-approved oral anthelmintic drug, exhibited potent antitumor activity in MM cells in vitro. It is demonstrated that PP inhibited MM cell proliferation and mediated apoptosis. Notably, PP markedly promoted the degradation of beta-catenin and abrogated its phosphorylation. PP triggered apoptosis in MM cells by inducing the release of cytochrome c and downregulating the expression of myeloid leukemia cell differentiation protein. In addition, PP effectively induced cell death in primary MM cells. In conclusion, PP may be a promising agent for the clinical treatment of MM.
