Progestin activation of nongenomic pathways via cross talk of progesterone receptor with estrogen receptor beta induces proliferation of endometrial stromal cells
(Endocrine Society, 2005-12)
Uterine decidualization is characterized by stromal cell proliferation and differentiation, which are controlled by ovarian hormones estradiol and progesterone. Here we report that the proliferative response of UIII rat ...
Occurrence of Sexual Hormones in Sediments of Mangrove in Brazil
(SPRINGER, 2011)
The presence of sexual hormones (female estrogens) was assessed in sediments of a mangrove located in the urban region of southern Brazil. The estrogens are involved in human sexual reproduction. They act as the chemical ...
Estrogen receptor-α promotes endothelial cell motility through focal adhesion kinase
(Oxford University Press, 2011-04)
Sex steroids play a key role in cell movement and tissue organization. Cell migration requires the integration of events that induce changes in cell structure such as protrusion, polarization and traction toward the direction ...
A transcriptomics model of estrogen action in the ovine fetal hypothalamus: evidence for estrogenic effects of ICI 182,780
(The Physiological Society, 2018-09)
Estradiol plays a critical role in stimulating the fetal hypothalamus?pituitary?adrenal axis at the end of gestation. Estradiol action is mediated through nuclear and membrane receptors that can be modulated by ICI 182,780, ...
17-β Estradiol e resveratrol nos parâmetros bioquímicos e hematológicos de ratas ovariectomizadas submetidas a desmielinização pelo brometo de etídio
(Universidade Federal de Santa MariaBRMedicina VeterináriaUFSMPrograma de Pós-Graduação em Medicina Veterinária, 2012-03-05)
Among the neurodegenerative diseases those involving the demyelination of the nervous system, such as multiple sclerosis (MS) that affects young and middle-aged adults, have great importance. Thus, the goal of this study ...
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 ...
Possible role of phytoestrogens in breast cancer via GPER-1/GPR30 signaling
(2018-12-01)
Estrogens generated within endocrine organs and the reproductive system act as ligands for at least three types of estrogen receptors. Estrogen receptors α (ERα) and β (ERβ) belong to the so-called classical family of ...
