(A) Cells were brought to 50% confluence and then cultured in RPMI 1640 with 10% FBS medium with DMSO or 15 µM 2Py for 48 h, cell lysates were isolated and Western blotting analysis performed using antibodies to Cyclin D1 (n=3), c-Myc (n=3), AR (n=3), PSA (n=3), and β-catenin (n=2) with β-actin as control (n=3). (B) Immunocytochemical analysis of β-catenin in LNCaP and C4-2 cells cultured in 10% FBS medium with DMSO or 15 µM 2Py for 24 h. Arrows indicate cytoplasmic relocalization of β-catenin after 2Py treatment.
