Primordial germ cells (spermatogonial stem cells) of bullfrogs express sex hormone-binding globulin and steroid receptors during seasonal spermatogenesis
(2013-01-01)
In vertebrate species, testosterone seems to inhibit spermatogonial differentiation and proliferation. However, this androgen can also be converted, via aromatase, into estrogen which stimulates spermatogonial differentiation ...

Aryl hydrocarbon receptor activation leads to impairment of estrogen-driven chicken vitellogenin promoter activity in LMH cells
(Elsevier Science Inc., 2013-03)
The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that mediates most of the toxic effects of environmental contaminants. Among the multiple pleiotropic responses elicited by AHR agonists, the ...
Estradiol stimulates cell proliferation via classic estrogen receptor-alpha and G protein-coupled estrogen receptor-1 in human renal tubular epithelial cell primary cultures
(Academic Press Inc Elsevier Science, 2019-04)
This work was aimed to determine the effect of 17β-estradiol (17βE) on cell proliferation in human renal tubular epithelial cells (HRTEC) isolated from kidneys from pediatric subjects, as well as the role of estrogen ...
Efeito do receptor de Estradiol ERβ na diferenciação de osteoclastos
(Universidade Federal de UberlândiaBrasilBiotecnologia, 2018)
Role of estrogen receptors, PKC and Src in ERK2 and p38 MAPK signaling triggered by 17β-estradiol in skeletal muscle cells
(Pergamon-Elsevier Science Ltd, 2010-10)
We have previously reported in C2C12 murine skeletal muscle cells that 10-8M 17β-estradiol promotes MAPKs stimulation which in turn mediates the activation of CREB and Elk-1 transcription factors. In this work, we demonstrated ...
The Subcellular Localization and Physiological Roles of Estrogen Receptors α and β in Classical and Non-Classical Tissues
(Nova Science Publishers, 2017)
It is now firmly established that estrogens elicit a variety of rapid effects in many tissues in addition to their delayed action on gene expression in the cell nucleus. Moreover, the classic estrogen receptors have been ...
Evaluation of estrogenic, antiestrogenic and genotoxic activity of nemorosone, the major compound found in brown Cuban propolis
(2013-07-31)
Background: Brown propolis is the major type of propolis found in Cuba; its principal component is nemorosone, the major constituent of Clusia rosea floral resins. Nemorosone has received increasing attention due to its ...
