Fulvestrant treatment caused a significant decrease in MDM2 protein expression in human breast cancer cell lines MCF7 and T47D, and that the reduction of MDM2 For example, the clustering analysis placed ICI 182 780 closer in its gene expression profile to low-dose 17β-estradiol treatment than the two other SERMs. Based on QRT-PCR results, Klk1 and Ihh expression changes in the ICI 182 780-treated mice also echoed those in mice treated with high-dose 17β-estradiol . Jul 21, 2014 · First, MCF7 cells were grown in E2-depleted media for three days and then treated with 50 μM ICI 182 780 (a specific ERα inhibitor also known as Fulvestran) for 24 h prior to the addition of 50 μM DIM for another 24 h. We observed a two-fold increase in CYP1A1 induction in cells treated with DIM and ICI compared to DIM alone (Figure 2A).

A high affinity estrogen receptor antagonist (IC50 = 0.29 nM), devoid of any partial agonism both in vitro and in vivo. Also high affinity agonist at the membrane

Fulvestrant is a high affinity estrogen receptor antagonist. IC 50 = 0.29 nM.

ICI 182,780, CAS: 129453-61-8, is an estrogen receptor inhibitor and GPR30 activator. MF: C32H47F5O3S, MW: 606.77. Cited in 53 publications

IC50 = 0.29 nM. Hence, it lacks estrogen agonist activity. Shown to be more effective than tamoxifen in reducing estrogen receptors in breast tumor cells.

Cited in 53 publications The estrogen antagonist ICI-182-780 does not inhibit the transformation phenotypes induced by 17-β-estradiol and 4-OH estradiol in human breast epithelial cells". International Journal of Oncology 26.2 (2005): 423-429.

Mar 28, 2002 · Read "The Estrogen Receptor Ligand ICI 182,780 Does Not Impair the Bone-Sparing Effects of Testosterone in the Young Orchidectomized Rat Model, Calcified Tissue International" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. of rats with 1, 1.5, and 2 mg of ICI/kg body weight/week resulted in a 2-, 7-, and 8-fold increase in IGFBP-3 tran-scripts. High doses of ICI increased mammary IGF-1gene expression by 2-fold (P < 0.01) but decreased IGF-1R and its autophosphorylation to 30% of the control mammary gland. IRS-1, IRS-2, and c-Raf-1 levels in the ICI-treated ICI 182 780 (Tocris Bioscience, Ellisville, MO, USA) treatments were performed at a final concentration of 1.0 and 0.1 μM. For Tamoxifen (Sigma–Aldrich) based studies, a final concentration of 1.0 μM or equal volumes of vehicle control were utilized.

following ICI 182 780, although to a lesser degree; again, combined anti-estrogen and SSE produced a dose-dependent regulation in TSP-1 and KLK6 tumor level, with a further reduction in the mRNA gene expression at 50 SSE (compared with ICI 182 780) and a partial reversion of the drug-induced down-regulation at 100 mg/kg per day. Determine the inhibitory effect of ICI 182780 on the development of metastasis, as measured by disease-free survival and overall survival, in women with operable stage I or II primary breast cancer. Determine toxicity of this regimen in these patients. OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. The impact of 17β-estradiol and antiestrogens on uterine cancer cells is poorly understood. The aim of this study was to determine the impact of 17β-estradiol, 4-hydroxytamoxifen, raloxifene and ICI 182 780 on the cell proliferation of six uterine cancer cell lines: HeLa, HEC-1-A, KLE, RL-95-2, Ishikawa and EN-1078D.

ICI 182,780, CAS: 129453-61-8, is an estrogen receptor inhibitor and GPR30 activator. MF: C32H47F5O3S, MW: 606.77. Cited in 53 publications Samples treated with 100 nmol/l ICI 182.780 (ICI) (Zeneca Pharmaceuticals, London, UK) were included as an anti-oestrogen control in all experiments. α-zearalanol and its metabolites (α-zearalenol, β-zearalanol, β-zearalenol, zearalenone and zearalanone) were obtained both from Sigma (Z0292, Z0166, Z0417, Z2000, Z2125, Z0167 respectively) and from The European Reference Laboratory (Laboratory for Residue Analysis, NL 3720 BA Bilthoven, The Netherlands). The anti-oestrogen ICI 182,780, but not tamoxifen, inhibits the growth of MCF-7 breast cancer cells refractory to long-term oestrogen deprivation through from Sigma (Poole, Dorset, UK). Dr A Fulvestran is a newer type of estrogen receptor (ER) antagonist with IC50 value of 9.4 nM [1]. Fulvestrant treatment caused a significant decrease in MDM2 protein expression in human breast cancer cell lines MCF7 and T47D, and that the reduction of MDM2 For example, the clustering analysis placed ICI 182 780 closer in its gene expression profile to low-dose 17β-estradiol treatment than the two other SERMs.
