Estrogens, estrogen receptors and melanoma
Expert Review of Anticancer Therapy, 2011The skin is the largest nonreproductive target tissue on which estrogen plays many beneficial and protective roles. Although neither exogenous hormones nor pregnancy represent significant risk factors for melanoma, epidemiological data suggest a higher survival rate in women with metastatic disease versus men and in premenopausal versus postmenopausal ...

Critical Reviews in Eukaryotic Gene Expression, 2002
Today we have to consider the existence of two estrogen receptors, alpha and beta, in our attempts to understand the role of estrogen receptors in physiology and pathology, and to explain the pharmacology of estrogens, antiestrogens, and SERMs. Both ERalpha and ERbeta belong to the large family of nuclear receptors that function as hormone-dependent ...

Molecular and Cellular Endocrinology, 1998
The purpose of this paper is to review potential novel functional pathways by which estradiol and estrogenic compounds elicit biological responses in mammals. We will limit our approach to those novel functions suggested by phenotypes associated with estrogen receptor-alpha (ER alpha) gene mutations and polymorphisms.

Estrogen receptors in the pancreas
Journal of Steroid Biochemistry, 1974Minced rat pancreas retained a large portion of estradiol (E2) after incubation with either 5 nM or 1 μM concentrations of radioactive E2. The mince was homogenized in low salt buffer and separated into nuclei, mitochondria, microsomes, and cytosol by centrifugations at 1000 g, 10,000 g, and 105,000 g, respectively.

Estrogen or estrogen receptor?
Trends in Endocrinology & Metabolism, 2003View Large Image | Download PowerPoint SlideAs a clinical breast oncologist, I was eager to review Endocrine Therapy in Breast Cancer. Hormonal manipulation has been the predominant form of breast cancer treatment for >50 years. Surgical ablation, high-dose estrogens, LHRH agonists and antiestrogens have all shown clinical benefit.

Estrogen receptor phosphorylation [PDF]
Steroids, 2003 Estrogen receptor alpha (ERalpha) is phosphorylated on multiple amino acid residues. For example, in response to estradiol binding, human ERalpha is predominately phosphorylated on Ser-118 and to a lesser extent on Ser-104 and Ser-106. In response to activation of the mitogen-activated protein kinase pathway, phosphorylation occurs on Ser-118 and Ser ...

Current Opinion in Obstetrics and Gynaecology, 1999
A significant flow of new data is currently being generated within the field of estrogen receptors and their mechanisms of action. This is primarily a result of the development of estrogen receptor knockout mice and the discovery of the second estrogen receptor, estrogen receptor beta.

The standardization of estrogen receptors
The Journal of Steroid Biochemistry and Molecular Biology, 1993Tumour estrogen receptor (ER) status may determine the medical treatment of a patient with breast cancer; yet inter-laboratory results can vary markedly, particularly when absolute cut-offs in fmol/mg cytosol protein are used. The use of standardized log units is proposed to permit greater inter-laboratory comparability.

Fulvestrant: an estrogen receptor antagonist that downregulates the estrogen receptor
Seminars in Oncology, 2003Fulvestrant, a novel antiestrogen classified as an estrogen receptor antagonist without known agonist effects, was recently approved in the United States for the treatment of postmenopausal, hormone receptor-positive women with progressive metastatic breast cancer after antiestrogen therapy.

Estrogen and estrogen receptors in thyroid carcinomas
Journal of Surgical Oncology, 1991AbstractThyroid tissues, composed of normal thyroid (10 cases), Graves' thyroid (4), and papillary carcinoma (10), were measured for the presence of receptors for estrogen (ER) using an enzyme‐immunoassay method. The mean value of ER in papillary carcinoma tissues (4.0 ± 3.6 fmol/mg protein) was higher than that in normal thyroid tissues (0.8 ± 0.4 ...
