Estrogen receptors and signaling pathways in lactotropes and somatotropes
Estrogens are crucial determinants in the regulation of anterior pituitary function and maintenance of tissue homeostasis. Estrogen actions in this gland are exerted through both classical and non-classical mechanisms of ...
Immunoexpression of aromatase and estrogen receptors β in stem spermatogonia of bullfrogs indicates a role of estrogen in the seasonal spermatogonial mitotic activity
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 ...
Estrogenic Compounds: Chemical Characteristics, Detection Methods, Biological and Environmental Effects
Several chemical compounds are being studied for their capacities to cause imbalances in several biological systems. Some of those are able to affect the endocrine system and are known as endocrine disruptors. Many negative ...

Estrogenic and mutagenic activities of crotalaria pallida measured by recombinant yeast assay and ames test
Background: Crotalaria pallida Ailton is a plant belonging to the Fabaceae family, popularly known as rattle or rattlesnake and used in traditional medicine to treat swelling of the joints and as a vermifuge. Previous ...
Perinatal estrogen exposure: Later repercussion on the fertility of rats
(Elsevier B.V., 1997-10-01)
The aim of the present study was to investigate the effects of perinatal estrogen exposure in the fertility of rats. Thus, rats were treated with estrogen on the 21st or 22nd day of intra-uterine life or treated with ...
Impact of estrogens and estrogen receptor-alpha in brain lipid metabolism
(American Physiological Society, 2018-07)
Estrogens and their receptors play key roles in regulating body weight, energy expenditure, and metabolic homeostasis. It is known that lack of estrogens promotes increased food intake and induces the expansion of adipose ...
