Fulvestrant also induces autophagy and apoptosis and has antitumor activity. Selleck's Fulvestrant has been cited by 88 publications Cancer Cell, 2020, S1535-6108 (20)30427-X Fulvestrant (ICI-182780) is an estrogen receptor (ER) antagonist with an IC50 of 9.4 nM in a cell-free assay. It shows potent inhibitory effect in the growth of MCF-7 human breast cancer cells, with an IC50 of 0.29 nM. [1] The androgen receptor (AR) plays a key role in the development and progression of prostate cancer. Targeting the AR for down-regulation would be a useful strategy for treating prostate cancer, especially hormone-refractory or androgen-independent prostate cancer.

The pure antiestrogen ICI 182,780 binds to the estrogen receptor with high affinity and is currently in clinical trials for the treatment of human breast cancer. We now show for the first time that ICI 182,780 also exhibits potent antiprogestin activity at doses frequently used in laboratory investigations. The antiprogestin activity of ICI 182,780 was detected in HeLa, HepG2, and CV1 cells

Yet the regulation of TGFβ in E2-induced dermal fibrosis remains ill-defined. Elucidating those regulatory mechanisms will improve the understanding of fibrotic disease pathogenesis and set the stage Pathways for ICI 182,780 Estrogen Signaling Pathway Estrogen is a steroid hormone that is responsible for the regulation of growth, differentiation and function of the reproductive system. Abstract ICI 182,780 is one of a new class of steroidal antiestrogens that differs from nonsteroidal antiestrogens, such as tamoxifen, in a number of respects. 1) It is bound by estrogen receptors with a high affinity, similar to that for estradiol. 2) It is a "pure" antiestrogen in that it does not mimic any of the effects of estradiol. 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. Decrease in BCL2 expression correlates with increased concentration of ICI 182,780 as described in literature.

Therefore, we tested the hypothesis that TAM and ICI rapidly facilitate lordosis via activation of GPER in the ARH. Our first experiment demonstrated that injection of TAM intraperitoneal, or ICI into the lateral ventricle, deactivated Dec 27, 2006 · Background ICI 182,780 (ICI) belongs to a new class of antiestrogens developed to be pure estrogen antagonists and, in addition to its therapeutic use, it has been used to knock-out estrogen and estrogen receptor (ER) actions in several mammalian species. In the present study, the effects and mechanism of action of ICI were investigated in the teleost fish, sea bream (Sparus auratus). Methods ICI 182,780 specifically down-regulates the estrogen receptor and, thus, represents the first of a new class of therapeutic agents. In this report, the authors present the current evidence that distinguishes ICI 182,780 from tamoxifen and related nonsteroidal compounds and establishes ICI 182,780 as the first in a new class of therapeutic macrophylla were used with a pure and well-characterized antiestrogen ICI 182,780 in a cotreatment regimen in vitro on cells transiently transfected with the estrogen [alpha] or [beta] receptor expression plasmids and in vivo in ovariectomized rats. Treatment with ICI 182780 also resulted in a significant reduction in pS2 expression ( P < 0.05) but this appeared unrelated to tumor ER status. In conclusion, ICI 182780 was well tolerated after short term administration and produced demonstrable antiestrogenic effects in human breast tumors in vivo , without showing evidence of agonist activity.

ICI 182,780 increased the open probability of BK(Ca) channels in inside-out patches with an EC(50) of 1 microM. These data suggest that molecules with the ability to bind nuclear estrogen receptors, regardless of oestrogenic or anti-estrogenic nature, activate BK(Ca) channels through this nongenomic, membrane-delimited mechanism.

To characterize further the potency and Moreover, ICI 182,780 had poor efficacy in blocking tamoxifen actions in T3-dependent responses. The results indicate that ICI 182,780, like tamoxifen, displays a duality in its pharmacological behavior which pivots on the T3 dependence of the estrogen response. ICI 182,780 (Faslodex™) from AstraZeneca (Cheshire, United Kingdom) is a novel, steroidal estrogen antagonist that was designed to be devoid of estrogen agonist activity in preclinical models.
