Abstract:
ABSTRACTAs adipose tissue depots are active endocrine organs, they secrete a variety of hormones (including estrogens from white adipose) and inflammatory mediators, which have important implications in numerous obesity‐associated diseases. Adipose tissues are broadly characterized as consisting of white, beige, and brown depot types. The endocrine, metabolic, and inflammatory profiles of adipose are depot dependent and influenced by the estrogenic and androgenic status of the adipose tissue. Estrogen receptors mediate both the genomic and nongenomic actions of estrogens and are expressed in t

AbstractBreast cancer etiology is associated with both proliferation and DNA damage induced by estrogens. Breast cancer risk factors (BCRF) such as body mass index (BMI), smoking, and intake of estrogen-active drugs were recently shown to influence intratissue estrogen levels. Thus, the aim of the present study was to investigate the influence of BCRF on estrogen-induced proliferation and DNA damage in 41 well-characterized breast glandular tissues derived from women without breast cancer.

Abstract:
Deleted in malignant brain tumors 1 (DMBT1) is a candidate suppressor of malignancies of the brain, lung, gut, and breast. We have been studying gene expression in the uterus in the presence of estrogens and their antagonists. Here, we show that DMBT1 RNA levels are robustly increased by estrogen treatment in the uteri of ovariectomized monkeys and rats. In monkeys, the progestin antagonist mifepristone inhibits estrogen-dependent uterine proliferation. As determined by a microarray experiment and quantitative analysis of RNA levels, mifepristone inhibited estrogenic induction of DMBT1. DMBT1

Although serum testosterone levels decrease acutely in critically ill patients, estrogen levels rise.

Each patient received priming doses of [14C]androgen and [3H]estrogen that were immediately followed by peripheral infusions for 210 min.

Estrogen plays an important role in skeletal physiology by maintaining a remodeling balance between the activity of osteoblasts and osteoclasts. In an attempt to decipher the mechanism through which estrogen elicits its action on osteoblasts, experimentation necessitated the development of a culturing environment reduced in estrogenic compounds. The selected medium (OPTI-MEM) is enriched to sustain cultures under reduced fetal bovine serum (FBS) conditions and is devoid of the pH indicator phenol red, a suspected estrogenic agent.

By using sex hormone-binding globulin (SHBG) transgenic mice, we produced a humanoid environment, and facilitated deposition and modulation of sex hormones.

There has been an increase in reports of male reproductive disorders that include male infertility and testicular cancer worldwide.

The response ofa testicular cell line to estrogenic pesticides was examined. The effect of estrogenic pesticides on the growth and protein levels of ERα and ERβ of mouse Sertoli cells was investigated. Pyrethroids are widely used insecticides due to their insecticidal

The gonadotropin-releasing hormone (GnRH) neurons of the hypothalamus are the principal regulators of reproductive function and are strongly modulated by estrogen (E₂).

One most interesting action of E₂ is that of modulating intracellular calcium concentration [Ca�⁺]I: this has been shown to happen in many different cell types, including embryonic models of GnRH neurons.

Abstract:
Background: Urinary Tract Infection (UTI) is a condition where pathogens invade the urinary tract and can travel up the urethra and into the bladder. UTIs occur more commonly in females compared to males and in the post-menopausal population this rate increases significantly. While these infections may be asymptomatic, they can also cause severe discomfort and lead to serious and even life threatening complications. Recent investigation into the vaginal microbiome has opened the doors to a possible mechanism behind the increased incidence of UTIs after menopause. Understanding the pathogenesis

Abstract:
Introduction: Approximately two-thirds of all breast cancer patients overexpress hormonal receptors and are treated with endocrine therapy, being tamoxifen (TAM) the standard treatment. However, many of the initial responders to TAM as first-line experience relapse. Several mechanisms have been proposed to explain the occurrence of acquired TAM resistance. Previous studies showed that estrogen receptor β (ERβ) expression is associated with better response to tamoxifen treatment, as the co-expression of ERα and ERβ is associated with TAM antiproliferative effects. Moreover, there is a growing i

Abstract:
Objective: Previous studies indicated a positive correlation between gastrin-releasing peptide receptor (GRPR) and estrogen receptor (ER) levels, suggesting a potential association between these receptors and tumor progression. This study aimed to verify the expression and prognostic implications of GRP and GRPR in breast cancer by analyzing multiple cancer-related databases. Methodology: The expression and prognosis of GRP and GRPR in breast cancer were assessed using different databases, including ONCOBD, Gent2, and Gene Expression Profiling Interactive Analysis (GEPIA).

Abstract:
Both the genes and cDNA sequences encoding the b-subunits of black carp LH and FSH were isolated, cloned and sequenced. Sequence analysis of the bcFSHb and LHb5'flanking regions revealed that the promoter region of both genes contains canonical TATA sequences, 30 bp and 17 bp upstream of the transcription start site of FSHb and LHb genes, respectively. In addition, they include several sequences of cis-acting motifs, required for inducible and tissue-specific transcriptional regulation: the gonadotropin-specific element (GSE), GnRH responsive element (GRE), half sites of estrogen and androgen
