Endometrial mucosa histopathology and hormonal receptors in postmenopausal women receiving hormone therapyAspectos histopatológicos y receptores hormonales en mucosa endometrial de mujeres posmenopáusicas con terapia hormonal
(Universidad Nacional Mayor de San Marcos, Facultad de Medicina Humana, 2005)
Regulation of aromatase expression in the anterior amygdala of the developing mouse brain depends on ERβ and sex chromosome complement
(Nature Publishing Group, 2017-12-13)
During development sex differences in aromatase expression in limbic regions of mouse brain depend on sex chromosome factors. Genes on the sex chromosomes may affect the hormonal regulation of aromatase expression and this ...
Estrogen and progesterone receptors have distinct roles in the establishment of the hyperplastic phenotype in PR-A transgenic mice
(BioMed Central, 2009-09)
Introduction: Expression of the A and B forms of progesterone receptor (PR) in an appropriate ratio is critical for mammary development. Mammary glands of PR-A transgenic mice, carrying an additional A form of PR as a ...
The tumor microenvironment modulates tamoxifen resistance in breast cancer: a role for soluble stromal factors and fibronectin through β1 integrin
(Springer, 2012-06)
Tamoxifen resistance has been largely attributed to genetic alterations in the epithelial tumor cells themselves, such as overexpression of HER-2/Neu. However, in the clinic, only about 15–20% of cases of HER-2/Neu ...
Glyphosate-based herbicide enhances the uterine sensitivity to estradiol in rats
(BioScientifica, 2018-11)
In a previous work, we detected that postnatal exposure to a glyphosate-based herbicide (GBH) alters uterine development in prepubertal rats causing endometrial hyperplasia and increasing cell proliferation. Our goal was ...
Estrogens in Human Male Gonadotropin Secretion and Testicular Physiology From Infancy to Late Puberty
(Frontiers Media, 2020-02)
Several reports in humans as well as transgenic mouse models have shown that estrogens play an important role in male reproduction and fertility. Estrogen receptor alpha (ERα) and beta (ERβ) are expressed in different male ...
17Beta-estradiol enhances leptin expression in human placental cells through genomic and nongenomic actions
(Society for the Study of Reproduction, 2010-07)
The process of embryo implantation and trophoblast invasion is considered the most limiting factor in the establishment of pregnancy. Leptin was originally described as an adipocyte-derived signaling molecule for the central ...
Estradiol and progesterone regulate proliferation and apoptosis in colon cancer
(BioScientifica, 2019-03)
Epidemiological studies describe estrogens as protectors in the development of colon cancer in postmenopausal women treated with hormone replacement therapy. However, the role of progesterone in colon cancer has been ...
