To study the effects of pSilencer 1.0-U6-siRNA-STAT3 on the growth of PC3 and LNCaP cells. Three pairs of DNA template coding siRNA were synthesized against STAT3 to reconstruct pSilencer 1.0-U6-STAT3-siRNA, which was transfected into PC3 and LNCaP cells. The STAT3 expression in PC3 cells and LNCaP were transfected with pSilencer 1.0-U6-siRNA-STAT3, and it was detected by Western blot and Northern blot. MTT and FCM were used to observe the growth-inhibiting ratio and apoptosis in PC3 cells. Western blot and Northern blot analyses demonstrated that pSilencer 1.0-U6-siRNA-STAT3 could significantly inhibit the expression of STAT3 in PC3 and LNCaP cells; MIT and FCM results showed that it could suppress the growth of PC3 cells and LNCaP and induce apoptosis of PC3 cells in vitro. PSilencer 1.0-U6-siRNA-STAT3 could significantly inhibit STAT3 expression, suppress the growth of PC3 and LNCaP cells and induce the apoptosis of PC3 cells.
