Experimental details

Western blot analysis of SRC1 was performed by loading 25 µg of LNCaP (lane 1), PC-3 (lane 2) and NIH-3T3 (lane 3) cell lysates onto an SDS polyacrylamide gel. Proteins were transferred to a PVDF membrane and blocked at 4ºC overnight. The membrane was probed with a SRC1 monoclonal antibody (Product # MA1-840) at a dilution of 1:2000 overnight at 4°C, washed in TBST, and probed with an HRP-conjugated secondary antibody for 1 hr at room temperature in the dark. Chemiluminescent detection was performed using Pierce ECL Plus Western Blotting Substrate (Product # 32132). Results show a band at ~152 and ~157 kDa.

Figure 4. NHERF2 and SRC-1 form a complex to enhance ERalpha transactivation. ( A ) NHERF2 enhances the activity of the steroid receptor coactivator 1 (SRC-1). Control MCF7 cells and FLAG-NHERF2-MCF7 cells were transfected with pcDNA-SRC1 vector and ERalpha activity was determined by luciferase assay using the ERE-TK-Luc reporter. The cells were grown in the absence (white bars) or presence (gray bars) of E2 for 48 h. All results were normalized to luciferase activity observed in control MCF7 cells transfected with empty pcDNA vector ('Control'). Results were expressed as mean relative luciferase activity +- S.E. ( B ) NHERF2 knockdown impairs SRC1 coactivator activity on ERalpha transactivation. MCF7 cells were transfected with pcDNA-SRC1 in the presence of an NHERF2-specific siRNA (gray bar) or an unrelated control siRNA (white bars) as described in Materials and Methods. ERalpha activity was determined using the ERE-luciferase reporter in the presence of 100 nM E2. The results were normalized to luciferase activity of control MCF7 cells transfected with empty pcDNA vector and the unrelated control siRNA. ( C ) NHERF2 interacts with ERalpha and SRC-1 in ZR-75-1 breast cancer cells. Whole cell protein extracts were subjected to IP using anti-ERalpha (upper panel), anti-SRC-1 (lower panel) followed by immunoblot using anti-NHERF2, anti-ER or anti-SRC-1 antibodies. As a negative control immunoprecipitation was performed using anti-IgG (IgG, upper and lower panels). (
