Astroglia are targets for estrogen and testosterone and are apparently involved in the action of sex steroids on the brain. Sex hormones induce changes in the expression of glial fibrillary acidic protein, the growth of astrocytic processes, and the degree of apposition of astroglial processes to neuronal membranes in the rat hypothalamus. These changes are linked to modifications in the number...
The importance of estrogens for the regulation of longitudinal bone growth is unequivocal. However, any local effect of estrogens in growth plate cartilage has been debated. Recently, several enzymes essential for estrogen synthesis were shown to be expressed in rat growth plate chondrocytes. Local production of 17beta-estradiol (E2) has also been demonstrated in rat costal chondrocytes. We aim...
Estrogen-responsive endometrial cancer (EC) is prevalent in uterine cancer. Its precise molecular mechanisms remain to be elucidated partly because of limited availability estrogen-sensitive EC models recapitulating clinical pathophysiology. We previously established patient-derived cell (EC-PDC) spheroid culture with high expression estrogen receptor α (ERα). Using this EC-PDC, we study the tr...
The steroidal regulation of vertebrate neuroanatomy and neurophysiology includes a seemingly unending list of brain areas, cellular structures and behaviors modulated by these hormones. Estrogens, in particular have emerged as potent neuromodulators, exerting a range of effects including neuroprotection and perhaps neural repair. In songbirds and mammals, the brain itself appears to be the site...
BACKGROUND Estrogen is an established enhancer of breast cancer development, but less is known on its effect on local progression or metastasis. We studied the effect of estrogen receptor recruitment on actin cytoskeleton remodeling and breast cancer cell movement and invasion. Moreover, we characterized the signaling steps through which these actions are enacted. METHODOLOGY/PRINCIPAL FINDIN...
STUDY OBJECTIVE Standard treatment for girls with labial fusion has included topical estrogen cream, manual separation, or surgery. Side effects may limit the use of topical estrogen. Betamethasone has recently shown efficacy at separating labial fusion. Local irritation and inflammation may be an initiator of labial fusion. No adverse effects of betamethasone treatment have been documented. Lo...
Effect of β-agonist on the dexamethasone-induced expression of aromatase by the human monocyte cells
Emerging evidence suggests that sex steroids are important for human skin health. In particular, estrogen improves skin thickness, elasticity and moisture of older women. The major source of circulating estrogen is the ovary; however, local estrogen synthesis and secretion have important roles in, for example, bone metabolism and breast cancer development. We hypothesized that infiltrated perip...
Binge eating afflicts approximately 5% of US adults, though effective treatments are limited. Here, we showed that estrogen replacement substantially suppresses binge-like eating behavior in ovariectomized female mice. Estrogen-dependent inhibition of binge-like eating was blocked in female mice specifically lacking estrogen receptor-α (ERα) in serotonin (5-HT) neurons in the dorsal raphe nucle...
OBJECTIVE To create an evidence-based position statement published by The North American Menopause Society (NAMS) on the role of local vaginal estrogen therapy (ET) for the treatment of vaginal atrophy in postmenopausal women. DESIGN NAMS followed the general principles established for evidence-based guidelines to create this document. A panel of clinicians and researchers acknowledged to be ...
