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.

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. 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 microarray analysis revealed that the metallothionein ( MT ) gene family was differentially expressed in tumors treated by these compounds.
