For total protein extraction, cells and tissue samples were washed with cold PBS prior to lysis with Laemmli Lysis Buffer (50 mM Tris–HCl pH 6.8, 2% SDS, 50 mM NaF, 10 mM β-glycerophosphate, 0.5 mM Na
3VO
4 and 1 × EDTA free protease inhibitors (Roche)) and then the cell lysates were normalized by
NanoDrop (Thermo Scientific). Western blotting was carried out as previously described [26 (
link)]. Briefly, samples were loaded on 8–10% acrylamide/bis-acrylamide gels and then transferred onto
PVDF membrane (Millipore) before immunoblotting with the appropriate primary antibodies overnight at 4 °C. Primary antibodies were used at the following concentrations; AR (dilution 1:000, Cell Signaling #5153), PSA (dilution 1:1000, Cell Signaling #2475), CDC6 (dilution 1:250, Santa Cruz #9964), p21
WAF1/Cip1 (dilution 1:500, Cell Signaling #2947),
E-Cadherin (CDH1; dilution 1:500, Cell Signaling #3195) and
GAPDH (dilution 1:2000, Cell Signaling #5174). Anti-mouse (Cell Signaling #7076) and anti-rabbit (Cell Signaling #7074) HRP-linked secondary antibodies were used at a dilution of 1:1000.
