Abstract：Objective To study the effects of S-adenosyl-homocysteine hydrolase inhibitor DZNep (3-Dea zaneplanocin A) on human prostatic cancer PC3 cells growth and further explore its potential value in anti-human prostatic cancer treatment.Methods MTT method was used to analyze the effects of EZH2 gene silencing,EZH2 over-expression and DZNep treatment on cell proliferation.Gene expression of EZH2,Bax and Bcl-2 in PC3 cells was detected with western blot.Results DZNep could significantly inhibit PC3 cell growth and induce apoptosis which was identified with Bax expression up-regulation and Bcl-2 expression down-regulation.EZH2 knock-down inhibited PC3 cells growth,and over-expression of EZH2 partially counteract the inhibitory effects of DZNep on PC3 cells growth.Conclusions DZNep can inhibit PC3 cells growth by targeting EZH2 inhibition which leads to endogenous apoptosis.DZNep has the potential value in the treatment of human prostatic cancer.
