We have investigated the effects of glycyrrhizin (GL) on cell proliferations of human stomach cancer KATO III and promyelotic leukemia HL-60 cells, and on DNA of those cell lines. GL displayed growth inhibitory effect against KATO III and HL-60 cells. Morphological change showing apoptotic bodies was observed in the KATO III and HL-60 cells treated with GL. The fragmentation of DNA by GL to oligonucleosomal-sized fragments that is a characteristic of apoptosis was observed to be concentration- and time-dependent in both cell lines. Caspase inhibitors such as Z-VAD-FMK and Z-Asp-CH2-DCB suppressed the DNA fragmentation induced by GL. The data of the present study show that the suppression of KATO III and HL-60 cell-growth by GL results from the induction of apoptosis by GL, and that caspase is involved in the induction of apoptosis by GL in these cells.
