Bladder samples were snap frozen in liquid nitrogen, homogenized with a mortar and pestle, and RNA extracted with the TRIzol (Invitrogen). Quantitative RT-PCR and western blot was performed as previously described39 (link)40 (link). The primers used for RT-PCR is listed below. Antibodies of mouse E-cadherin (20874-1-AP), Vimentin (10366-1-AP), Snail1 (13099-1-AP), Snail2 (Slug, 12129-1-AP), Twist1 (18125-1-AP), Zeb1 (21544-1-AP) and beta-actin (60008-1-Ig) were provided by ProteinTech.
