Abstract:
The growth inhibition and pro-apoptosis effects of dracorhodin perchlorate on human prostate cancer PC-3 cell line were examined.After administration of 10-80 μmol/L dracorhodin perchlorate for 12-48 h,cell viability of PC-3 cells was measured by MTT colorimetry.Cell proliferation ability was detected by colony formation assay.Cellular apoptosis was inspected by acridine orange-ethidium bromide fluorescent staining,Hoechst 33258 fluorescent staining,and flow cytometry (FCM) with annexin V-FITC/propidium iodide dual staining.The results showed that dracorhodin perchlorate inhibited the growth of PC-3 in a dose- and time-dependent manner.IC50 of dracorhodin perchlorate on PC-3 cells at 24 h was 40.18 μmol/L.Cell clone formation rate was decreased by 86％ after treatment with 20 μmol/L of dracorhodin perchlorate.Some cells presented the characteristic apoptotic changes.The cellular apoptotic rates induced by 10-40 μmol/L dracorhodin perchlorate for 24 h were 8.43％ to 47.71％ respectively.It was concluded that dracorhodin perchlorate significantly inhibited the growth of PC-3 cells by suppressing proliferation and inducing apoptosis of the cells.
