Central Expression of Sex Steroid Receptors during the Ring Dove (Streptopeliarisoria) Breeding Cycle
… regions of the preoptic-hypothalamus of both sexes. In the anterior and posterior hypothalamus, high density of AR-ir and PR-ir neurones was concentrated and co-localised in the nucleus preopticus anterior (POA), nucleus preopticus mediahs (POM), nucleus medialis, pars medianis (POMm), nucleus …

Hormonal modulation of sex steroid hormone receptors and oncogenes in human breast cancer cells
Since sex steroids modulate breast tumor growth, and high levels of the HER-2/neu protooncogene protein may contribute to breast cancer metastasis, the effects of estrogen, progestin and hormone antagonists on the levels of estrogen receptor (ER), progesterone receptor (PR) and HER-2/neu mRNA and …

Localisation of sex steroid receptors and effect of Tamoxifen upon glioma cell lines in vitro
… This study investigated the expression of sex steroid receptors in glioma cell lines using molecular biology technique (RT-PCR), and immunological tecimique (Dot blot, and Western blot). The cells were then separated in different groups of treatment (Tamoxifen, or estradiol and a …

Genetic and Sex Steroid Hormone Contributions to the Sexual Dimorphism in Murine Experimental Allergic Encephalomyelitis
… with susceptibility to EAE. Further, the role of sex steroid hormones and parent-of-origin effects were studied through the use of reciprocal crosses of SJL/J and BI0.S/SgMcdJ mice. We found that adult gonadal hormones selectively regulate sexually dimorphic quantitative traits observed in EAE at …

Sex- and Training-Related Differences in Metabolic, Sex Steroid and Growth Hormone Responses During Prolonged Exercise
… (3) male runners, and (4) female runners. Sex- and training-related differences in resting levels and responses were described for glucose (GLU), lactic acid (HLa), hematocrit (Hct), respiratory exchange ratio (R), growth hormone (hGH), estradiol-B17 (E(,2)), and testosterone (T). Blood …

Determining the endometrial phenotype of women with abnormal uterine bleeding
… conditions. Fibroids and adenomyosis are sex-steroid dependant conditions, and lines of evidence suggest there is an impaired progesterone response in the endometrium from women with adenomyosis, however, there is a dearth of evidence related to the endometrium from women with fibroids. …

Carotenoid metabolism in mice and prostate cancer risk
… in CMO-I KO, CMO-II KO, and WT mice on sex steroid hormone status. Lycopene preferentially accumulated in CMO-II KO mice while β-carotene preferentially accumulated in CMO-I KO mice. Phytofluene and phytoene accumulation was not altered by genotype. Together these data suggest that …

Dietary Soy Protein Isoflavonoid Effects on the Reproductive Tract of the Nonhuman Primate and Neoplastic Human Prostate Gland
… tissue hormone concentrations, prostate tissue sex steroid receptor expression levels, androgen and estrogen receptor polymorphisms, and diet have all been proposed to explain these discrepancies in prostate cancer incidence in men living in Western countries when compared to men living in Asia. …

Sex differences in human perinatal development and autism
… females. To explain this, in 2014, the prenatal sex steroid theory was proposed. This extended the fetal testosterone theory, published in 2004. The prenatal sex steroid theory proposes that exposure to higher levels of prenatal sex steroids (e.g., prenatal androgens and estrogens) that are on …

The immediate and long-term consequences of temporary exposure during adulthood to di(2-ethylhexyl) phthalate and diisononyl phthalate on female reproduction
… structure that produces a variety of sex steroid hormones and participates in several feedback loops within the hypothalamic-pituitary-ovary axis. Further, it is the site of storage and maturation of the female gamete: the oocyte. Females are born with a finite number of oocytes in the …

Male Subfertility and Prostate Cancer Risk: Epidemiological and Genetic Studies
… PCa risk in subfertile men, including in the sex steroid signaling pathway and aryl hydrocarbon receptor (AHR) pathway, which mediates some of the effects of endocrine disrupting chemicals, and also in PCa risk genes implicated in previous genome-wide association studies. Our main findings …

The transgenerational effects of Di(2-ethylhexyl) phthalate on female reproduction in mice
… The primary roles of the ovary are to produce sex steroid hormones and maintain a steady stream of growing follicles. Normal sex steroid hormone production by the mature follicles is essential for the maintenance of normal menstrual/estrous cyclicity, reproductive tract tissues, and …

Effects of fescue toxicosis and chronic heat stress on murine hepatic gene expression
… resulted in down-regulation of genes involved in sex-steroid pathway and in cholesterol and lipid metabolism. Genes coding for ribosomes and protein synthesis were up-regulated by the E+ diet. Mice were also used to study the effects of chronic heat stress on hepatic gene expression. Twenty-five …

Mechanism of Bisphenol A toxicity in adult mouse ovarian antral follicles
… processes such as ovarian follicle growth and steroidogenesis. Follicles are the functional units of the ovary, responsible for ovulating an oocyte and producing sex steroid hormones during steroidogenesis. Follicles grow and develop from primordial, primary, pre-antral, and finally, to antral …

Mechanisms by which di(2-ethylhexyl) phthalate and mono(2-ethylhexyl) phthalate disrupt ovarian folliculogenesis and steroidogenesis
… function is required for reproductive health and steroid hormone controlled non-reproductive health. Two ovarian processes that are essential for normal ovarian function are folliculogenesis and steroidogenesis. Follicles are the functional units of the ovary containing the oocyte required for …

Equol inhibits growth, induces atresia, and inhibits steroidogenesis of mouse antral follicles
Equol is a non-steroidal estrogen metabolite produced by microbial conversion of daidzein, a major isoflavone phytoestrogen in soybean, in the gut of some humans and many animal species. Previous studies indicate that isoflavones and their metabolites can affect endogenous estradiol production, …
