Phytoestrogens can produce inhibitory effects on gonadotropin secretion in both animals and humans, although little is known about the mechanisms and the role of direct action on oestrogen receptors (ER) in this process. We examined the effect of cou

We describe an assay employing the competitive binding of estrogen receptor (ER) with basal transcription factors on a constitutive promoter (cytomegalovirus-hormone response element[s]-chloramphenicol acetyltransferase [CMV-(HRE)n-CAT, containing a

Background Premature thelarche is defined as breast development before 8 years of age. This is most often caused by central hormone disregulation and is accompanied by concurrent bone maturation. However, we present a case of premature thelarche with

The relationship of the classical receptors and their transcriptional activity to nongenotropic effects of steroid hormones is unknown. We demonstrate herein a novel paradigm of sex steroid action on osteoblasts, osteocytes, embryonic fibroblasts, an

Recently, we developed a novel triaryl-substituted pyrazole ligand system that has high affinity for the estrogen receptor (ER) (Fink, B. E.: Mortenson, D. S.: Stauffer, S. R.; Aron, Z. D.: Katzenellenbogen, J. A. Chem. Biol. 1999, 6, 205). Subsequen

This study examines whether the serine/threonine protein kinase, Akt, is involved in the cross-talk between epidermal growth factor (EGF) and insulin-related growth factor I (IGF-I) receptors and ER-alpha. Treatment of MCF-7 cells with either EGF or

Estrogen receptor alpha (ERalpha) is a soluble protein that mediates the effects of the gonadal estrogens such as 17beta-estradiol. Upon ligand binding, a cytoplasmic pool of ERalpha translocates to the nucleus, where it acts as a transcription facto

We have studied the two estrogen receptor (ER) subtypes, ER alpha and ER beta, and chimeric constructs with ER alpha and ER beta to examine the bioactivities of these receptors and their responses to estrogen and antiestrogen ligands. Transcriptional

Antiestrogens have proven to be highly effective in the treatment of hormone-responsive breast cancer. However, resistance to antiestrogen therapy often develops. In addition, although tamoxifen-like antiestrogens are largely inhibitory and function
