Effect of small heterocyclic compound S1 on inducing PC3 cell line apoptosis / 吉林大学学报(医学版)

ABSTRACT

Objective To study the effect of small heterocyclic compound 8-oxo-3-thiomorpholino-8H-acenaphtho pyrrole-9-carbonitrile(S1) on apoptosis of human androgen independent prostatic carcinoma cells line(PC3) and its mechanism.Methods PC3 cells were cultivated,and divided into different groups 10.00,5.00,1.00,0.50,0.10,0.05 and 0.01 ?mol?L-1 S1 groups,meanwhile,PC3 control group and cyclophosphamide group were set up.MTT was used to detect the inhibitory rate of PC3 cell proliferation.Flow cytometry was used to detect the inducing effect of S1 on apoptosis of PC3 cells.Caspase 3,8,9 kits were used to detect apoptosis route.Results The inhibitory rates of PC3 cells induced by 0.10-10.00 ?mol?L-1 S1 were significantly higher than that in cyclophosphamide group(P
