Estrogens and development.
The normal development of the genital organs of mammals, including humans, is under hormonal control. A role for the female sex hormone estrogen in this process is still unclear. However, exposure of experimental animals or humans to the potent exogenous estrogen, diethylstilbestrol (DES), results in persistent differentiation effects. Since many chemicals in the environment are weakly estrogen...
متن کاملEnvironmental estrogens alter early development in Xenopus laevis.
A growing number of environmental toxicants found in pesticides, herbicides, and industrial solvents are believed to have deleterious effects on development by disrupting hormone-sensitive processes. We exposed Xenopus laevis embryos at early gastrula to the commonly encountered environmental estrogens nonylphenol, octylphenol, and methoxychlor, the antiandrogen, p,p-DDE, or the synthetic andro...
متن کاملRole of estrogens in development of prostate cancer.
Estrogens have previously been extensively used in prostate cancer treatment. Serious side effects, primarily in cardiovascular system have, however, limited their use. The therapeutic effect of estrogen in preventing prostate cancer growth was mainly obtained indirectly by feedback inhibition of the hypothalamic release of LRH leading to lowered serum androgen levels and castration like effect...
متن کاملEstrogens and atherosclerosis.
Numerous epidemiological as well as experimental studies have suggested that estradiol (E2) prevents atherosclerosis development. However two controlled prospective and randomized studies in women using hormone replacement therapy (HRT) did not confirm this beneficial effect. We then decided to use mouse models of atherosclerosis to define the possible mechanisms involved and the reasons for th...
متن کاملEstrogens and brain function.
Cognitive decline is well recognized during ageing but is often accelerated in women after menopause. Studies have shown that there are significant gender differences in brain ageing with significantly greater changes in brain structure, function and metabolism between females and males. Estrogens exert protective effects on neuronal cells in culture but the exact underlying mechanism for their...
