| 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.
