Abstract :
[en] The viability, cytolysis and apoptosis-mediated cellular death induced by giganteosides D and E (Gig-D and Gig-E) and hederacolchisides A and A1 (Hcol-A and Hcol- A1) were analysed in HL-60 cells. Materials and Methods: the end-point metabolic (WST1) and lactate dehydrogenase (LDH) assays were used. Cell cycle analysis and apoptosis were measured by flow cytometry, DNA laddering and caspase 3 analyses. Results: the HL-60 cell line was more sensitive to Hcol-A1 and Gig-D (IC50 3-5 ÌM) than to Gig-E and Hcol-A (IC50 8-13 ÌM; WST1 assay). This was related to LDH release. The induction of apoptosis could be detected without caspase 3 activation after 24 h of treatment. DNA fragmentation could be detected only with Gig-D. With Hcol- A1 and Gig-D, an accumulation of cells in the S-phase and an increase of cells in sub-G1 peak were observed. By the annexinV-fluorescein isothiocyanate (FITC)/7-aminoactinomycin D (AAD) assay, the majority of cells were in late apoptosis with Gig-D, and in necrosis with Hcol-A1. Conclusion: Hcol-A1 is more cytotoxic than Gig-D, followed by Gig-E and finally Hcol-A. This is related to a membrane permeabilization effect, leading to cytolysis
