Apr 24, 2003 · Following induced estrus, 3 heifers per treatment were randomly assigned to receive uterine infusion of a control solution (0.1% BSA in saline), or estradiol-17β (117 ng/dose; Sigma, Saint Louis, MO), or ICI 182, 780 (3 mg/dose, Tocris, Avonmouth, Bristol, United Kingdom) or recombinant ovine IFN-τ (0.25 mg/dose = biological activity of 5 May 11, 2005 · 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). We conclude that exogenous E 2 β‐induced increases in UBF in the Ovx animal and endogenous E 2 β‐mediated elevations of UBF during the follicular phase and late pregnancy are partially mediated by ER The anti-estrogen ICI 182, 780 is classified as a pure antiestrogen due to its lack of estrogen-like activity [22,23]. ICI 182,780 acts by binding ER, which causes disassociation of receptor associated proteins and results in impaired receptor dimerisation and increased receptor degradation [22,23]. 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). The effects of estrogen, its antagonist ICI 182, 780, and IF.-tau on the expression of estrogen receptors and integrin alphaV beta 3 on cycle day 16 in bovine endometrium.

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.

1mg. 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.
