Estradiol and Testosterone Regulate Arginine-Vasopressin Expression in SH-SY5Y Human Female Neuroblastoma Cells Through Estrogen Receptors-α and -β
(Endocrine Society, 2013-06-01)
The expression of arginine-vasopressin (AVP) is regulated by estradiol and testosterone in different neuronal populations by mechanisms that are not yet fully understood. Estrogen receptors (ERs)have been shown to participate ...
Estrogen and progesterone modulation of eosinophilic infiltration of the rat uterine cervix
(Elsevier Science Inc, 2000-07)
Ripening of the rat cervix involves widespread collagenolysis that follows an eosinophilic leukocyte infiltration. The hormonal control of these events is not well understood. The aims of this study were to investigate the ...
The effect of anandamide on prolactin secretion is modulated by estrogen
(National Academy of Sciences, 2003-02)
Recent research has revealed that endogenous cannabinoid receptors (CB1 and CB2) react with the active ingredient of marijuana, Δ9-tetrahydrocannabinol. Two endogenous ligands activate these receptors. The principal one, ...
Evaluation of Estrogenic Potential of Flavonoids Using a Recombinant Yeast Strain and MCF7/BUS Cell Proliferation Assay
(2013-10-01)
Phytoestrogens are of interest because of their reported beneficial effects on many human maladies including cancer, neurodegeneration, cardiovascular disease and diabetes. Furthermore, there is a search for compounds with ...

Effect of estrogen on intracellular signaling pathways linked to activation of M-2- and M-3-muscarinic acetylcholine receptors in the rat myometrium
(Elsevier B.V., 2000-02-25)
The estrogen treatment of adult female rats induces an increase in myometrium sensitivity to cholinergic agonists and in this tissue the presence of M-2- and M-3-muscarinic acetylcholine (mACh) receptor was shown. We now ...
Contribution of alpha(2)-adrenoceptors to the mitogenic effect of catecholestrogen in human breast cancer MCF-7 cells
(Elsevier, 2008)
Catecholestrogens are estrogen metabolites formed by hydroxylation of 17beta-estradiol and estrone at either the C-2 or C-4 position, rivaling the parent estrogens in concentration. The objective of the present work was ...
Paxillin, a novel controller in the signaling of estrogen to FAK/N-WASP/Arp2/3 complex in breast cancer cells
(Elsevier Ireland, 2016-07-15)
Breast cancer is the major cause of cancer-related death in women. Its treatment is particularly difficult when metastasis occurs. The ability of cancer cells to move and invade the surrounding environment is the basis of ...
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 ...
