Abstract

Seed oil ofBrucea javanica(BJO) is extracted from the seeds of herb medicineBrucea javanica(L.), and its emulsion formulation (BJOE) has been used clinically to treat carcinomas for many years in China. The antileukemia potential of BJO was investigated in human acute myeloid leukemia cell lines (AML) U937 and HL-60in vitroand in a mouse U937 xenograft tumor model. BJO induced AML cell apoptosis through activation of caspase-8 and modulation of apoptosis-related proteins. Meanwhile, the inhibition of survivin and XIAP increased the cytotoxicity of BJO. Consistent with these findings, BJO also increased subG1phase cells and cause PARP cleavage in AML patients' leukemia cells. In contrast, only weak cytotoxicity of BJO was found in peripheral blood lymphocytes (PBLs) of healthy volunteers. Moreover, oleic acid and linoleic acid were found to be the active components of BJO. Our study provided strong evidence for the first time that BJO induced apoptosis of both cultured and primary AML cells. Furthermore, intravenous injection of BJO significantly inhibited U937 tumor growth in the xenograft mouse model. These results suggest that BJO may have a therapeutic role in the treatment of human leukemia.
