ABSTRACT
Objective To study the effect of grape seed procyanidin extract(GSPE) on the cell cycle arrest in human bladder cancer BIU87 cells and investigate the underlying molecular mechanism.Methods BIU87 cells were treated with different concentrations of GSPE(50,100 and 200 ?g/ml) and cultured for 24 h.The untreated group served as control.Flow cytometry was used to evaluate the cell cycle,and RT-PCR and Western blotting were used to detect the mRNA and protein expressions of CyclinD1 and cyclin-dependent kinase 4(CDK4).Results GSPE inhibited the cell growth through cell cycle arrest at G1 phrase in a dose-dependent manner.Semi-quantitated RT-PCR and Western blot analyses indicated that GSPE decreased CyclinD1 and CDK4 expressions in a dose-dependent fashion(P
