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. Fulvestrant is the first "pure" antiestrogen with no agonistic activity both in vitro and in vivo. OSTI.GOV Journal Article: 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 ICI 182, 780 (Faslodex™), a steroidal estrogen antagonist, is the first in a new class of agent—an estrogen receptor downregulator. Pre-clinical breast cancer models show that ICI 182, 780 leads to a prolonged duration of response, and that it exerts its effects via a different mode of action to tamoxifen.

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.
