1mg. Fulvestrant (ICI 182, 780) is a selective estrogen receptor downregulator (SERD) and potent antiestrogen. In estrogen receptor-alpha-positive ERalpha (+) breast cancer, the drug immobilizes ERalpha in the nuclear matrix, inducing receptor polyubiquitination and subsequent degradation via the 26S proteasome. The new, steroidal anti‐estrogen ICI 182,780 was tested for its ability to inhibit the proliferation of a tamoxifen‐resistant variant of the parental MCF‐7 human breast‐cancer cell line. Fulvestrant (ICI 182 780, ICI) has been used in treating patients with hormone-sensitive breast cancer, yet initial or acquired resistance to endocrine therapies frequently arises and, in particular, cancer recurs as metastasis. Fulvestrant Ici 182 780, supplied by Tocris, used in various techniques.

After 24 h, cells were treated with 10 nM E 2 (17 β-estradiol, Sigma #E2758), 10 nM fulvestrant (F, ICI 182, 780, Tocris #1047), 0.5 to 50 μ M BP-3 (Sigma #H36206) or 0.5 to 50 μ M PP (Sigma #P53357).

Currently, ICI is used for the treatment of advanced breast cancer that is resistant to other endocrine therapies. It Yan Chen, Zheng Li, Yan He, Dandan Shang, Jigang Pan, Hongmei Wang, Huamei Chen, Zhuxia Zhu, Lei Wan, Xudong Wang, Estrogen and pure antiestrogen fulvestrant (ICI 182 780) augment cell–matrigel adhesion of MCF-7 breast cancer cells through a novel G protein coupled estrogen receptor (GPR30)-to-calpain signaling axis, Toxicology and Applied Purpose: Thyroid disease is a frequent comorbidity in women with breast cancer, and many require thyroid hormone replacement therapy (THRT). We postulated that THRT has a deleterious clinical effect mechanistically through hormonal interactions, nuclear receptor cross-talk, and upregulation of high-risk breast cancer genes. Experimental Design: Observational studies of patients with lymph node Fulvestrant (ICI 182 780, ICI) has been used in treating patients with hormone-sensitive breast cancer, yet initial or acquired resistance to endocrine therapies frequently arises and, in particular, cancer recurs as metastasis. We demonstrate here that both 17-beta-estradiol (E2) and ICI enhance cell adhesion to matrigel in MCF-7 breast cancer cells, with increased autolysis of calpain 1 (large subunit) and proteolysis of focal adhesion kinase (FAK), indicating calpain activation.

Interestingly, the combination of ICI 182, 780 (fulvestrant) and HCQ was less effective than HCQ alone at inhibiting tumor growth. However, the combination of tamoxifen and HCQ was able to restore anti-estrogen sensitivity and reduce tumor growth.

Fulvestrant treatment caused a significant decrease in MDM2 protein expression in human breast cancer cell lines MCF7 and T47D, and that the reduction Fulvestrant (ICI 182,780) is a selective estrogen receptor down-regulator (SERD). Fulvestrant is a high affinity estrogen receptor antagonist. IC 50 = 0.29 nM.
