Abstract
- Tanshinone II-A is a derivative of phenanthrene-quinone isolated from Salvia
miltiorrhiza BUNGE, a traditional herbal medicine that is known to induce
antiinflammatory, anti-oxidative and cytotoxic activity. We have examined
cellular effects of Tanshione II-A on HL60 human promyelocytic leukemic cells
and K562 human erythroleukemic cells. Tanshione II-A induced a dose- and
time-dependent DNA fragmentation into the multiples of 180 bp and specific
proteolytic cleavage of poly(ADP-ribose) polymerase in both cell lines.
PI-staining and flow cytometry analysis of K562 cells following Tanshione II-A
treatment showed an increase of the cells possessing hypodiploid DNA indicative
of apoptotic state of cells. Caspase-3 activity was significantly increased
during Tanshinone II-A treatment of both HL60 and K562 cells, whereas caspase-1
activity was not changed. These results suggest that Tanshione II-A induced HL60
and K562 cellular apoptosis that may be associated with the selective members of
caspase family. Copyright 2000 Academic Press.
