Objective: To study the effects of curcumol on the expression of apoptosis induce factor(AIF)
poly ADP-ribose polymerase(PARP)and caspase-3 protein in lung cancer cell A549. Method: A549 cells were treated with different concentrations(0
12.5
25
50
100 mg·L-1)of curcumol for 48 hours
then the total protein was extracted from each group respectively. The expression of AIF
PARP and caspase-3 was detected by Western blotting. Result: The PARP and AIF protein expressions were significantly elevated in the treatment groups(1.661 3 and 2.212 4 respectively)compared with the model group(0.545 3 and 0.358 6 respectively)
in a dose dependent manner(P<0.01). The caspase-3 precursor(32×103)protein expression showed no significance difference among all the groups. Conclusion: Curcumol could induce apoptosis through caspase-independent pathway in human lung cancer cell A549
whose mechanism might be linked to up-regulation of the PARP protein and translocation of AIF.
