SATB1 expression is correlated with the invasion ability of prostate cancer cells. A-C: The invasion of LNCaP, DU-145 and PC-3 cells was measured by Transwell chamber. A, DU-145. B, PC-3.C, LNCaP. Magnification: 200×. D: Western blot analysis of the relative protein level of SATB1 in LNCaP, DU-145 and PC-3 cells (n = 3). β-actin served as loading control. *P < 0.05 compared to DU-145 cells. Note that SATB1 antibody could not detect SATB2 protein in the cell lysates.
