Abstract:
This study was purposed to explore the biological effects suppressing growth and inducing apoptosis of Chinese medicine compound FFJZ on leukemia cell line K562 and its possible mechanisms of FFJZ. The growth status of K562 cells cultured in vitro was determined by trypan blue exclusion test; the suppressive effect of FFJZ on K562 cells was assayed by MTT method; the inducing apoptosis of FFJZ on K562 cells was detected by flow cytometry. The results showed that after K562 cells were treated with FFJZ in certain concentration range, the inhibited rate of FFJZ on K562 cell growth was remarkably increased along with enhancement of FFJZ, the IC(50) value of FFJZ on K562 cells was 5.6 mg/ml after treatment for 48 hours. At 4 mg/ml of FFJZ the early apoptosis predominated in K562 cells, at 8 mg/ml of FFJZ the late apoptosis ratio significantly increased. As compared with control group without FFJZ, there was significant difference (p < 0.01). It is concluded that the FFJZ in range of certain concentration can suppress growth and proliferation of K562 cells and induce their apoptosis in concentration-dependent manner, the mechanism of which may be associated to inducing apoptosis of K562 cells.
