ABSTRACT
OBJECTIVE:
To investigate the effects of curcumin on the proliferation, apoptosis, and cell cycle of human acute myeloid leukemia cell line K562.METHODS:
MTT method was used to detect the proliferation inhibition of logarithmic growth phase human acute myeloid leukemia K562 cells, flow cytometry was used to detect the cell cycle, Annexin V-FITC was used to detect the apoptosis rate, and real-time fluorescent quantitative PCR and Western blot were used to detect the expression of Bax, BCL-2 and caspase-3 mRNA and protein, respectively.RESULTS:
The inhibition rate of cell proliferation in curcumin 10, 20, and 40 µmol/L group for 24 h and 48 h were higher than that in the control group (curcumin 0 µmol/L), and the cell proliferation inhibition rate was concentration-time dependent (r=0.879, r=0.914). The proportion of G0/G1 cells and apoptosis rate of K562 cells in the curcumin 10, 20, and 40 µmol/L group were higher than those in the control group, and showed drug concentration dependent (r=0.856, r=0.782). The expression of Bax and Caspase-3 mRNA in the curcumin 10, 20, and 40 µmol/L group was higher, while BCL-2 mRNA was lower than those in the control group, and showed drug concentration dependent (r=0.861, r=0.748, r=-0.817). The gray value of Bax protein expression in the curcumin 10, 20, and 40 µmol/L group was higher than that in the control group, while the gray value of BCL-2 and Caspase-3 protein expression was lower than that in the control group, and showed drug concentration dependent (r=0.764, r=-0.723, r=-0.831).CONCLUSION:
Curcumin can inhibit the proliferation of human acute myeloid leukemia cell line K562 cells, block the cell cycle at G0/G1 phase, promote cell apoptosis, and induce apoptosis by regulating Bax, BCL-2, and Caspase-3.Palavras-chave
