Abstract:
Objective To evaluate whether down-regulating antizyme inhibitor(AZIN) can regulate the expression of ornithine decarboxylase(ODC) and the proliferation of prostate cancer cell PC3 or not.Methods siRNA-AZIN transfected prostate cancer cell PC3,the level of antizyme(AZ),AZIN and ODC were measured by RT-PCR and westernblot. MTT was used to measure the proliferation of cells. Results The mRNA level of AZIN declined(P<0.01);the protein level of AZIN and ODC declined(P<0.05). Knockdown of AZIN significantly inhibited the proliferation of PC3(P<0.05). Conclusions Transfecting siRNA-AZIN can decrease the level of AZIN, then the decline level of ODC inhibits the proliferation of PC3.
