Methods CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The nonsteroidal antiestrogen EM-800 is approximately 10-fold more potent than ICI 182 780, the most potent known steroidal antiestrogen, at inhibiting estrone-stimulated uterine weight in ovariectomized mice (half-maximal inhibitory daily sc doses of 0.2 and 2.0 g, respectively). Differential effects of estrogen and estrogen receptor antagonist, ICI 182 780, on the expression of calbindin-D9k in rat pituitary prolactinoma GH3 cells. Overview of attention for article published in International journal of clinical and experimental pathology, December 2014 Our previous study revealed that the ectoplasmic specialization (ES) was deleted by the treatment of anti-estrogen, ICI 182.780 (ICI), and anti-androgen, flutamide (FLUT) in mouse testis. Also, expression of cortactin, an F-actin-binding protein, was decreased by the treatment of FLUT in mouse testis.
