ABSTRACT
OBJECTIVE:
To investigate the effect of 4' -hydroxywogonin on proliferation and apoptosis of human acute lymphoblastic leukemia SUP-B15 and Jurkat cells, and to analyze its possible mechanism.METHODS:
SUP-B15 and Jurkat cells were cultivated in vitro and treated with different concentrations of 4' -hydroxywogonin, the inhibitory effect of 4' -hydroxywogonin on the proliferation of SUP-B15 and Jurkat cells was detected by CCK-8 method; the cell apoptosis was examined by the flow cytometry with Annexin V-APC/7-AAD donble staining; the expression of C-MYC, BCL-2 and cleaved caspase 3 in SUP-B15 and Jurkat cells were measured with Western blot.RESULTS:
4' -hydroxywogonin inhibited the proliferation of SUP-B15 and Jurkat cells in a dose-dependent manner (r=0.78, r=0.89), with IC50 value of (6.32± 0.53) µg/ml in SUP-B15 cells and (12.04± 0.42) µg/ml in Jurkat cells at 24 h. The early apoptotic rate of cell was also enhanced with the increase of 4' -hydroxywogonin concentrations. The results of Western blot showed that 4' -hydroxywogonin could down-regulate the expression of proliferation-related molecule C-MYC(P<0.01) and apoptosis-related molecule BCL-2(P<0.01), the expression of apoptosis-related molecule cleaved caspase 3 was up-regulate(P<0.01).CONCLUSION:
4' -hydroxywogonin shows the effects of anti-tumor by inducing cell apoptosis and inhibiting cell proliferation, its molecular mechanism maybe relate with down-regulation of C-MYC and BCL-2 expression and up-regulation of the cleaved caspase 3 expression.
