ABSTRACT
Aim To study the effective mechanism of curcumin on abnormal cell cycle and apoptosis of serum-deprived PC12 cells induced by ?-amyloid peptide 25-35(A?25-35).Methods Synchronized PC12 cells were pretreated with 5 ?mol?L-1 Cur for 1 h,and then 25 ?mol?L-1 A?25-35 for 24 h.Protein and mRNA expression of p21,CDK4,E2F1 and bax were detected by RT-PCR and Western blot respectively.Results After synchronized PC12 cells being pretreated with 5 ?mol?L-1 Cur for 1 h,the mRNA and protein expression of p21 gene were increased gradually,while CDK4,E2F1 and bax gene were decreased.Conclusion Cur maybe effects the redistribution of cell cycle and apoptosis of serum-deprived PC12 cells induced by A?25-35,through increasing the mRNA and protein expression of p21,and decreasing the mRNA and protein expression of CDK4,E2F1 and bax gene.
