Senescence and steroid hormone receptor reactivities in accessory sex glands of elderly rats (Sprague-Dawley) following exogenous hormonal therapy
(Churchill LivingstoneEdinburghEscócia, 2012)
The phthalate DEHP modulates the estrogen receptors α and β increasing lactotroph cell population in female pituitary glands
(Pergamon-Elsevier Science Ltd, 2020-11)
Humans are exposed to numerous endocrine disruptors on a daily basis, which may interfere with endogenous estrogens, with Di-(2-ethylhexyl) phthalate (DEHP) being one of the most employed. The anterior pituitary gland is ...
Inhibition of mammary tumor growth by estrogens: Is there a specific role for estrogen receptors alpha and beta?
(Springer, 2010-10)
To evaluate the extent to which each estrogen receptor (ER) subtype contributes to the stimulation or to the inhibition of mammary tumor growth, we evaluated the effects of specific agonists in MC4-L2 cells, which are ...
The Impact of Estrogen and Estrogen-Like Molecules in Neurogenesis and Neurodegeneration : Beneficial or Harmful?
(2021-03-08)
Estrogens and estrogen-like molecules can modify the biology of several cell types. Estrogen receptors alpha (ERα) and beta (ERβ) belong to the so-called classical family of estrogen receptors, while the G protein-coupled ...
Immunoexpression of aromatase and estrogen receptors beta in stem spermatogonia of bullfrogs indicates a role of estrogen in the seasonal spermatogonial mitotic activity
(Elsevier B.V., 2013-02-01)
Bullfrog stem spermatogonia, also named primordial germ cells (PGCs), show strong testosterone immunolabeling in winter, but no or weak testosterone immunoexpression in summer. Thus, the role of testosterone in these cells ...
Estrogen receptor beta (ER beta) mediates expression of beta-catenin and proliferation in prostate cancer cell line PC-3
(Elsevier Ireland Ltd, 2016)
The aim of the present study was to characterize the mechanism underlying estrogen effects on the androgen-independent prostate cancer cell line PC-3. 17 beta-estradiol and the ER beta-selective agonist DPN, but not the ...
Melatonin and ethanol intake exert opposite effects on circulating estradiol and progesterone and differentially regulate sex steroid receptors in the ovaries, oviducts, and uteri of adult rats
(2013-08-01)
Chronic ethanol intake is associated with sex hormone disturbances, and it is well known that melatonin plays a key role in regulating several reproductive processes. We report the effects of ethanol intake and melatonin ...
