Abstract
Objective:To study whether NF-κB has the relationship with the apoptosis effect of daunorubicin (DNR) on HL-60 cells in vitro.Methods:This study observed the apoptosis of HL-60 by optic microscope,flow cytometry (FCM) and detected expression or activation of NF-κB with immunocytochemistry (IC) and flow cytometry (FCM) or EMSA of the groups:control HL-60 cells,HL-60 cells treated with DNR,HL-60 cells treated PDTC or FBI before DNR.Results:When treated with 1.0 μmol/L DNR,there showed the typical apoptotic cells.It was shown that after HL-60 cells were treated with 1.0 μmol/L DNR,the expression of NF-κB increased markedly compared with the control HL-60 cells.When adding PDTC,this effect of DNR was decreased,but FBI hadn′t presented these activation.Conclusion:It is suggested from the results that NF-κB has something to do with this apoptosis process and ROS had the marked correlation with the apoptosis process.
