A cell-permeable estradiol derivative that acts as an estrogen antagonist and down-regulates estrogen receptors without affecting estrogen Fulvestrant (ICI 182,780) is a selective estrogen receptor down-regulator (SERD).

ICI significantly decreased the size of the lobular structures, Ki-67 labeling index, andinsulin-like growth factor binding protein (IGFBP)-2and IGFBP-5gene expression. Treatment 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

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 Fulvestrant, sold under the brand name Faslodex among others, is a medication used to treat hormone receptor (HR)-positive metastatic breast cancer in postmenopausal women with disease progression as well as HR-positive, HER2-negative advanced breast cancer in combination with palbociclib in women with disease progression after endocrine therapy. In late pregnant sheep ICI 182 780 also mildly and acutely (for 5–30 min) elevated mean arterial pressure and heart rate (P < 0.05).

Breast cancer is a sex steroid hormone-dependent malignant neoplasia. The role of oestradiol in this malignancy has been well documented Genistein versus ICI 182, 780: an ally or enemy in metastatic progression of prostate cancer. Hisae Nakamura et.

The immunoprecipitation results confirmed that CaBP-9k interacts directly with ERα, and E2 increases the interaction between CaBP-9k and ERα. tamoxifen, 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. The effects of these compounds on the cell proliferation of the six uterine cancer cell lines were studied in the presence and absence of estrogens (phenol red and serum deprivation of sex steroids). fulvestrant Faslodex Pharmacologic class: Estrogen receptor antagonist Therapeutic class: Antineoplastic Pregnancy risk category D Action Inhibits cell division by binding with and downgrading estrogen receptor protein in breast cancer cells Availability Prefilled syringes: 125 mg/2.5 ml, 250 mg/5 ml Indications and dosages Hormone receptor-positive Using a second xenograft model which was derived from another patient, we showed that genistein promoted disease progression in vivo and ICI 182, 780 inhibited metastatic spread. The microarray analysis revealed that the metallothionein ( MT ) gene family was differentially expressed in tumors treated by these compounds.

ICI 182 780 suppressed the stimulatory effect of E2 on CaBP-9k expression in GH 3 cells. The level of CaBP-9k expression was significantly reduced by co-administration of E2 with ICI 182 780 in GH 3 cells. The immunoprecipitation results confirmed that CaBP-9k interacts directly with ERα, and E2 increases the interaction between CaBP-9k and ERα.

Additionally, an ER antagonist (ICI 182 780) was used as an inhibitor of ER to examine the potential involvement of the ER pathway in the induction of CaBP-9k in GH3cells. Co-immunoprecipitation was used to determine if CaBP-9k interacts directly with ER and whether or not the expression of CaBP-9k in GH3cells is related to an ER pathway. The effects of estrogen, its antagonist ICI 182, 780, and interferon-tau on the expression of estrogen receptors and integrin alphaV beta 3 on cycle day 16 in bovine endometrium.
