Abstract

Ailanthus altissima belonging to the family Simaroubaceae has been used to settle an upset stomach, to combat a fever, and as an insecticide. Apoptosis is an active process, which is a critical feature of the regulated development of multicellular organisms. We investigated whether the extract of A. altissima induced apoptotic cell death in Jurkat T-acute lymphoblastic leukemia (ALL) cells. Upon treatments with the extract, the dose-dependent inhibitions of cell viability were observed. It also caused apoptosis as measured by cell morphology and DNA fragmentation. The capability of the extract to induce apoptosis was associated with proteolytic cleavage of specific target protein such as poly(ADP-ribose)polymerase (PARP) protein, suggesting the possible involvement of the activations of caspases. Further study showed that Bcl-2 protein levels were not changed in all treated groups compared to control group. These results suggest that A. altissima induces Bcl- 2-independent apoptosis in Jurkat T cells.
