Article Title: SHBG Is an Important Factor in Stemness Induction of Cells by DHT In Vitro and Associated with Poor Clinical Features of Prostate Carcinomas

Figure Lengend Snippet: (A) Stronger immunocytochemical staining of SHBG is shown in LNCaP and PC-3 cells treated with DHT (left panel, bar scale: 50 µm). Immunoblotting demonstrates higher levels of SHBG, Oct3/4 and Nanog expressions in the cells treated with DHT (right panel). (B) SHBG specific siRNA results. SHBG knockdown in both LNCaP and PC-3 cells was verified by immunoblotting (left panel); 10 nM DHT induces expressions of Oct3/4 and Nanog in the cells transfected with the siRNA control, but such an induction disappears in the cells transfected with the specific SHBG siRNA (right panel). (C) LNCaP and PC-3 cells treated with specific SHBG siRNA grow relatively slower compared to the cells cultivated with control siRNA. (* means P <0.05). (D) Flowcytometry of CD44 and CD90 (left and right panel, respectively). While 10 nM DHT treatment for 48 hrs induces its expression in both cell lines for both genes (left parts of both panels), there is no CD44 and CD90 expression difference in these cells after specific SHBG siRNA knockdown compared to the siRNA control cells (right parts of both panels).
Article Snippet: SHBG siRNA (sc-44847) and siRNA control (sc-33007) for transient transfection were obtained from Santa Cruz Biotechnology.
