Coactivation of HE11/Sp1 by DRIP150 in ZR-75 (A), MCF-7 (B) and MDA-MB-231 (C) cells and ERΔZF1/Sp1 (D) and ERΔZF2/Sp1 (E) in ZR-75 cells. Cells were transfected with pSp13 and ERα deletion mutants, treated with DMSO or E2, and luciferase activity was determined as described in the Materials and Methods. Significant coactivation by DRIP150 is indicated (**). Coactivation with lower concentration of DRIP150 (i.e. 2.5 and 5.0 ng) were not observed in experiments summarized in Figures 2A and 2C (data not shown).
