Objective:To investigate the preventive effect of erythropoietin(EPO) on doxorubicin(DOX)-induced apoptosis in myocardial cells of rats.Methods:Cells were cultured in vitro and treated with different concentrations(6.25
50
100 IU /ml) of EPO for 24 hours
then the myocardial cells were exposed to DOX(5 μg/ml).After 24 hours
the apoptosis ratio was detected by flow cytometry
and cell viability was detected by methyl thiazolyl tetrazolium.The expression of apoptotic protein Bcl-2/Bax was detected by flow cytometry.Results:The antiapoptotic effect of EPO was in a concentration manner.The survival rate of cells was increased
and the apoptosis ratio decreased.Conclusion:EPO has protective effect against DOX-induced apoptosis in myocardial cells.EPO may increase the expression of apoptosis protein Bcl-2/Bax and decrease the apoptosis ratio.
