Hemochromatosis is an inherited or secondary disorder caused by excessive iron storage leading to multiple organ damage. We describe 2 patients with diabetes mellitus caused by hemochromatosis secondary to multiple blood transfusions due to severe aplastic anemia. Subject 1, who was diagnosed with severe aplastic anemia at 15 years of age, received multiple red blood cell transfusions before he underwent autologous peripheral blood stem cell transplantation (PBSCT) at 22 years of age. At 21 years of age, hyperglycemia was detected with increased hemoglobin A1c and serum ferritin levels, 9...

Depression and use of antidepressant medications are both associated with increased risk of obesity, potentially attributed to a reduced serotonin transporter (SERT) function. However, how SERT deficiency promotes obesity is unknown. Here, we demonstrated that SERT (-/-) mice display abnormal fat accumulation in both white and brown adipose tissues, glucose intolerance and insulin resistance while exhibiting suppressed aromatase (Cyp19a1) expression and reduced circulating 17β-estradiol levels. 17β-estradiol replacement in SERT (-/-) mice reversed the obesity and glucose intolerance, supporting a role for estrogen in SERT deficiency-associated obesity and glucose intolerance...

Primary ovarian insufficiency describes a spectrum of declining ovarian function and reduced fecundity due to a premature decrease in initial follicle number, an increase in follicle destruction, or poor follicular response to gonadotropins. The sequelae of primary ovarian insufficiency include vasomotor symptoms, urogenital atrophy, osteoporosis and fracture, cardiovascular disease, and increased all-cause mortality. In women with primary ovarian insufficiency, systemic hormone therapy (HT) is an effective approach to treat the symptoms of hypoestrogenism and mitigate long-term health risks if there are no contraindications to treatment...

A Japanese senior high school girl aged 18 years and 5 months with growth hormone deficiency was referred for primary amenorrhea. Her height was 1.36 m, and her bodyweight was 23.5 kg. She had received daily growth hormone therapy from the age of 5 years. Growth hormone therapy was discontinued at the age of 16 years and 11 months, and estrogen-replacement therapy (ERT) was started to stimulate secondary sexual characteristics. Although ERT was performed until the age of 18 years and 11 months, genital bleeding did not occur...

Epidemiological data demonstrated that hormone replace treatment has protective effect against colorectal cancer (CRC). Our previous studies showed that this effect may be associated with DNA mismatch repair. This study aims to investigate the mechanism of estrogen induction of MLH1, and whether colorectal tumor proliferation can be inhibited through induction of MLH1 by estrogen signal pathway. Human CRC cell lines were used to examine the regulation of MLH1 expression by over-expression and depletion of estrogen receptor-α (ERα) and estrogen receptor-β (ERβ), under the treatment with 17β-estradiol or β-Estradiol 6-(O-carboxy-methyl)oxime:BSA, followed by a real-time Q-PCR and Western blotting analysis...

Bisphenol A (BPA; 4-[2-(4-Hydroxyphenyl)propan-2-yl]phenol), a suspected endocrine disruptor with a weak estrogenic activity is used in a variety of consumer products, including food contact materials made of paper and cardboard products. Due to restrictions for the use of BPA because of its potential health risks, BPA is gradually being replaced by other bisphenols, as no limitations exist for these substances. The present study presents a method for the simultaneous analysis of bisphenol A (BPA), bisphenol AF (BPAF), bisphenol B (BPB), bisphenol E (BPE), bisphenol F (BPF) and bisphenol S (BPS) in paper and board products, using gas chromatography-tandem mass spectrometry (GC-MS/MS)...

BACKGROUND: Estrogens are critical players in prostate growth and disease. Estrogen therapy has been the standard treatment for advanced prostate cancer for several decades; however, it has currently been replaced by alternative anti-androgenic therapies. Additionally, studies of its action on prostate biology, resulting from an association between carcinogens and estrogen, at different stages of life are scarce or inconclusive about its protective and beneficial role on induced-carcinogenesis...

Background. Our previous Gräfenberg spot findings confirmed that the distal-third areas of the anterior vaginal wall bore a significantly greater number of nerves and sexual hormone may have certain degree of influence on these significant differences. However, the role of estrogen in vaginal innervations remains controversial. Methods. To investigate whether hormonal-neural interactions occur in the vagina, sixty rats were randomly divided into six groups: Sham-operated, ovariectomy, and 4 treatment groups...

INTRODUCTION: Modifiable lifestyle factors have been consistently associated with breast cancer, and risk may vary by menopausal status. However, whether these associations vary according to age among postmenopausal women remains unresolved. METHODS: Using postmenopausal women from a population-based case-control study (990 cases and 1006 frequency-matched controls), we conducted multivariable-adjusted unconditional logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for lifestyle factors (lifetime alcohol intake, body mass index [BMI] in the year before diagnosis, lifetime recreational physical activity [RPA], and nonsteroidal anti-inflammatory drug use) in association with breast cancer stratified by age (<65 vs...

BACKGROUND: Association between exogenous estrogen intake and cholelithiasis risk has been reported in several epidemiological studies, including oral contraceptive (OC) and hormone replacement therapy (HRT), while the results were controversial. This study aimed to perform a comprehensive meta-analysis of this issue. METHODS: PUBMED, EMBASE, and Cochrane library database were searched up to October 2016. Two reviewers independently extracted data from eligible studies, relative risks (RRs), and/or odds ratios (ORs) with 95% confidence intervals (95% CIs) for the highest versus lowest categories of intake were adopted...

Background: Plasma aldosterone/renin ratio (ARR) is the most popular screening test for primary aldosteronism (PA). Because both estrogen and progesterone (including in oral contraceptive agents) affect aldosterone and renin levels, we studied effects of combined hormonal replacement therapy (HRT) on ARR, measuring renin as both direct renin concentration (DRC) and plasma renin activity (PRA). Methods: Fifteen normotensive, healthy postmenopausal women underwent measurement (seated, midmorning) of plasma aldosterone, DRC, PRA, electrolytes and creatinine and urinary aldosterone, cortisol, electrolytes and creatinine at baseline and after 2 weeks and 6 weeks treatment with combined HRT (conjugated oestrogens 0...

Hormone replacement therapy (HRT) is necessary in adolescents with primary ovarian insufficiency (POI) in order to avoid estrogen deficiency. The goal of this minirewiew is to present the different types of estrogens (17β-estradiol, estradiol valerate, ethinyl estradiol, and combined equine estrogens) as well as the different types of progestins available. In order to choose among the different types of HRTs, the features of each regimen are being discussed as well as their risks and their respective benefits...

INTRODUCTION: Selective estrogen receptor modulators (SERMs) have been used off-label in men for more than 50 years. SERMs exert their action on the estrogen receptor agonistically or antagonistically. A fundamental knowledge of the complex molecular action and physiology of SERMs is important in understanding their use and future directions of study in men. AIM: To review the basic science and mechanism of the action of estrogens, the estrogen receptor, and SERMs, and the existing clinical publications on the use of SERMs in men for infertility and hypogonadism with their strengths and weaknesses and to identify the need for future studies...

Kisspeptins are considered critical regulators in the hypothalamic-pituitary-gonadal axis because they can stimulate secretion of Gonadotropin-releasing hormone in mammals, and may also mediate the feedback regulation of sex steroids in the hypothalamus. Two kiss1 paralogues (kiss1 and kiss2) were identified in teleosts, hinting at their increased complexity of signaling for sex-steroid feedback regulation. In the present study, molecular pathways by which 17β-estradiol (E2 ) exerted feedback regulation on two kiss genes, via three types of estrogen receptors, were investigated in the protogynous orange-spotted grouper (Epinephelus coioides)...

High sodium, high glucose, and obesity are important risk factors for age-related diseases such as cardiovascular disease (CVDs), stroke, and cancer. Coupling factor 6 (CF6) is released from vascular endothelial cells and functions as a circulating peptide that inhibits prostacyclin and nitric oxide generation by intracellular acidosis. High glucose elevates CF6 by activation of protein kinase C and p38 mitogen-activated protein kinase, whereas CF6 causes type 2 diabetes mellitus, resulting in a high glucose vicious cycle...

The molecular mechanism by which 17β-oestradiol (E2) increases urethral tone is unclear. As human tissue is limited in availability, we explored changes in the urethras of ovariectomized (OVX) mice. Twenty-four virgin female mice were randomised into three groups: mice with a sham operation only (control), OVX mice without E2 replacement (OVX), and OVX mice with E2 replacement (OVX + E2). Two weeks after the ovariectomy, mice received either E2 or placebo for 4 weeks. Leak point pressure (LPP) and maximum urethral closure pressure (MUCP) were assessed in these mice at 6 weeks after OVX, under anaesthesia...
