Decursin is a major component of the root of Angelica gigas(Umbelliferae), which has been traditionally used in Korea as a tonic and to treat anemia, hemiplegia, and women’s diseases. The objective of this study is to identify the anti-cancer mechanism induced by decursin on apoptosis of human leukemia and lymphoma cells. Cytotoxicity of decursin on U937, HL- 60, MOLT-4, THP-1 cells showed the significant effects. First of all, IC<SUB>50</SUB> of decursin on four cell lines was 27.1, 32.4, 17.4, 15.1 μM, respectively. So IC<SUB>50</SUB> in THP-1 cells was the smallest among 4 cell lines treated with decursin(15.1 μM). In order to understand the apoptosis-mechanism by decursin, we examined the gene expression of bcl- (anti-apoptotic), bax(pro-apoptotic) and p53(tumor suppressor)after treating the THP-1 cells with decursin(10, 50 and 100 μM). It was found bcl-2 gene was decreased dose dependently, the expression level of bax gene of THP-1 cells treated with 100 μM of decursin was about 3 times higher than those of control, and p53 gene was increased In the same concentration(100 μM), p53 gene was increased dose dependent manner. In protein express, bcl-2 and p53 protein showed a tendency to decrease. bax was increased about 4 fold. Therefore decursin is a useful chemotherapeutic agent against leukemia.
