Objective:To observe the protective effect of cryptotanshinone on glutamate-induced apoptosis in cultured cortical neurons.Methods:Cell viability was detected by MTT assay.Intracellular reactive oxygen species(ROS) level was detected using DCFH-DA.The apoptosis rate was measured by Hoechst 33342
and the expression of Bcl-2 was detected by Western blot.Results:Compared with glutamate group
cryptotanshinone could increase cell survival rate
decrease apoptosis rate and the level of intracellular ROS.Moreover
cryptotanshinone could remarkably increase the expression of Bcl-2 protein and decrease Bax protein.Conclusion:Cryptotanshinone could significantly protect cortical neurons from the apoptosis induced by glutamate
the mechanisms of which may be the inhibition or decrease of ROS formation
