Fulvestrant also induces autophagy and has antitumor efficacy. - Mechanism of Action & Protocol. ICI 182,780 was a more effective inhibitor of MCF-7 growth than 4'-hydroxytamoxifen, producing an 80% reduction of cell number under conditions where 4'-hydroxytamoxifen achieved a maximum of 50% inhibition. Sustained antioestrogenic effects of ICI 182,780, following a single parenteral dose of ICI 182,780 in oil suspension, were apparent in ICI 182,780 is an estrogen receptor inhibitor and GPR30 activator. Purity: ≥98%. Category: Chemicals Protein Interacting Inhibitors Activators Substrates Protein MCF-7 cells were treated with 10 nmol/L E 2, 10 nmol/L ICI 182,780 (ICI), E 2 + ICI 182,780 (E2+ICI), 100 ng/mL leptin (LPT), or ICI 182,780 + leptin (ICI+LPT) for 24 hours or were left untreated (SFM).

Targeting the AR for down-regulation would be a useful strategy for treating prostate cancer, especially hormone-refractory or androgen-independent prostate cancer. In the present study, we showed that the antiestrogen fulvestrant [ICI 182,780 (ICI)] effectively suppressed AR expression in ICI 182,780 increased the open probability of BK(Ca) channels in inside-out patches with an EC(50) of 1 microM.
