title: Induction of apoptosis by lupeol isolated from mokumen (Gossampinus malabarica L. Merr) in human promyelotic leukemia HL-60 cells.
abstract: We have investigated the effect of lupeol (lup-20(29)-ene-3beta-ene-3-ol) isolated from mokumen (Gossampinus malabarica L. Merr) on DNA of human promyelotic HL-60 leukemia cells. Induction of apoptosis by lupeol was observed in human leukemia HL-60 cells. Morphological change showing apoptotic bodies was observed in the HL-60 cells treated with lupeol. The fragmentation of DNA by lupeol to oligonucleosomal-sized fragments that is a characteristic of apoptosis was observed to be concentration- and time-dependent in the HL-60 cells. Flow cytometric analysis showed that the hypodiploid nuclei of HL-60 cells were increased to 28.5, 42.0 and 70.9% after a 3-day treatment with 75, 100 and 150 micro M lupeol, respectively. The data of the present study show that the suppression by lupeol of growth of the HL-60 cells results from the induction of apoptosis by this compound.
