Effect of Annonaceous Acetogenin on Proliferation and Apoptosis of Raji Cell / 中国中医药信息杂志

ABSTRACT

Objective To investigate the effects of annonaceous acetogenin on proliferation and apoptosis in Raji cells and its mechanism.Methods Raji cells cultured in vitro were divided into control group,annonaceous acetogenin group and adriamycin group.Raji cells were effected by 6.25,12.5,25,50 ?g/mL annonaceous acetogenin.Proliferation of Raji cells were evaluated by MTT assays,apoptosis percentage was assessed by flow cytometry.Caspase-9 protein was detected by immunohistochemistry.Results The Raji cell proliferation rate of annonaceous acetogenin decreased compared with the control,that of 25,50 ?g/mL group were lower than adriamycin group,and it was related to the concentration,relying on the incubating time.The apoptosis rate was higher than control,that of 25,50 ?g/mL group were higher than adriamycin group,and it was related to the concentration and the incubating time.The expression of caspase-9 protein of annonaceous acetogenin group was higher than control,and it had a positively relationship with the concentration and incubating time.Conclusions Annonaceous acetogenin could inhibit cell proliferation in a dose-dependent and time-dependent manner in Raji cells,and it may induce Raji cells apoptosis by up-regulating caspase-9 expression.
