Leptin, critical in regulation of energy metabolism, is also important for normal bone growth, maturation and turnover. Compared to wild type (WT) mice, bone mass is lower in leptin-deficient ob/ob mice; osteopenia in growing ob/ob mice is due to decreased bone accrual, and is associated with reduced longitudinal bone growth, impaired cancellous bone maturation and increased marrow adipose tissue (MAT). However, leptin deficiency also results in gonadal dysfunction, disrupting production of gonadal hormones which regulate bone growth and turnover...

We previously reported that the cutaneous vasodilator response to local warming in males required noradrenaline (NA) and neuropeptide-Y (NPY). Animal work has shown no role for NPY in female vascular control. We investigated the contribution of NA and NPY in human female cutaneous vascular control. Nine female and nine male participants volunteered. To elucidate whether synthetic oestrogen and progesterone altered cutaneous vascular responses, females were tested in high-hormone (HH) and low-hormone (LH) phases of oral contraceptive pill (OCP)...

INTRODUCTION: Given the current postulated plasticity between epithelial and mesenchymal states of migratory cancer cells the detection of non-epithelial CTCs is an important scientific and clinical goal. METHODS: We used the filtration-based ISET technology to enrich circulating tumour cells (CTCs) in early breast cancer blood samples and identify them using a morphology-based immunocytochemistry (ICC) approach. RESULTS: We found greater numbers of putative CTCs by this approach than by the cytokeratin-based CellSearch technology, but a high number of CTC false positives were identified in healthy volunteer samples which were not reduced in successive blood draws...

AIMS: Progesterone receptor (PR) expression is prognostic in early stage breast cancer. There are several reports of discordant expression between primary tumour and axillary lymph node (ALN) metastasis expression of oestrogen receptor (ER) and PR. We sought to determine whether expression of these biomarkers in the synchronous ALN metastases of ER positive (+), HER2 negative (-) breast cancer could provide more accurate prognostic information. METHODS: The retrospective cohort included 229 patients from a single institution with ER+, HER2- breast cancer who had synchronous ALN metastatic disease (2005-2014)...

Among 95,057 patients ≥50 years with new anti-osteoporosis medications (AOM) (2001-2013) in primary care, 1-year cessation was 51% (28%-68%), higher in men, smokers, patients with missing lifestyle data, and out normal BMI, and lower in those aged 60-79, with recent fractures or other anti-osteoporotics, suggesting non-severe osteoporosis and less risk awareness. PURPOSE: Low compliance to anti-osteoporosis medications (AOM) has been previously reported. We aimed to estimate 1-year cessation rates of different AOMs as used in Spanish healthcare settings, and to identify associated risk factors...

Vulvar and vaginal atrophy (VVA) is a chronic medical condition in postmenopausal women, which is predominantly due to a permanent cessation of ovarian oestrogen production. Current available treatment options for VVA are over-the-counter (OTC) symptomatic relief products or local oestrogen therapy (LET) aiming to treat this underlying atrophic condition. Recent surveys indicated that these products decrease sexual spontaneity, are messy and indiscrete. Ospemifene is an oral daily drug, which has proven to treat vaginal dryness and dyspareunia effectively...

During their lifetime, females are subjected to different nutritional and hormonal factors that could increase the risk of obesity and associated comorbidities. From early postnatal periods until the postmenopausal phase, exposure to over nutrition, high-energy diet and oestrogen deficiency, are considered as significant obesity risk factors in women. In this study, we assessed how key transitional life events and exposure to different nutrition influence energy homeostasis in a rat model. Specifically, we assessed the sequential exposure to postnatal over nutrition, high-fat diet (HFD) after weaning, followed later by ovariectomy (OVX; as a model of menopause)...

BACKGROUND: Hot flushes affect 70% of menopausal women and often severely impact physical, psychosocial, sexual, and overall wellbeing. Hormone replacement therapy is effective but is not without risk. Neurokinin B signalling is increased in menopausal women, and has been implicated as an important mediator of hot flushes. METHODS: This phase 2, randomised, double-blind, placebo-controlled, single-centre, crossover trial assessed the effectiveness of an oral neurokinin 3 receptor antagonist (MLE4901) on menopausal hot flushes...

Male breast cancers constitute less than 1% of all the breast cancers. Papillary carcinoma is a very rare tumour of the male breast. Due to rarity, Fine Needle Aspiration Biopsy (FNAB) findings of papillary carcinoma in male breast are seldom reported. A 55-year-old male presented with a lump in the left breast of two years' duration. FNAB was reported as fibroadenoma. Histopathological examination of the excised breast lump revealed invasive papillary carcinoma. Immunohistochemistry showed expression of pancytokeratin, oestrogen receptor, and progesterone receptor...

Bisphenol A (BPA) is considered a potent endocrine disruptor, causing changes in the endocrine system due to its oestrogenic activity. Male individuals may be susceptible to endocrine, morphological and physiological alterations during testicular postnatal development. The aim of the present study was to evaluate whether exposure to BPA during the peripubertal period can damage testicular development. To this end, male Wistar rats were treated with BPA via gavage at doses of 20 or 200µgkg-1 on Postnatal Days (PND) 36-66...

BACKGROUND: Constitutional mismatch repair deficiency syndrome results from bi-allelic inheritance of mutations affecting the key DNA mismatch repair genes: MLH1, MSH2, MSH6 or PMS2. Individuals with bi-allelic mutations have a dysfunctional mismatch repair system from birth; as a result, constitutional mismatch repair deficiency syndrome is characterised by early onset malignancies. Fewer than 150 cases have been reported in the literature over the past 20 years. This is the first report of the founder PMS2 mutation - NM_000535...

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...

The oestrogen receptor-related receptors (ERRs) are orphan nuclear receptors that were originally identified on the basis of their close homology to the oestrogen receptors. The three mammalian ERR genes participate in the regulation of vital physiological processes including reproduction, development and metabolic homeostasis. Although unique ERRs have been found in insects, data on the function and regulation of these receptors remain sparse. In the present study, a 2095-bp full-length cDNA encoding an ERR, termed AiERR, was isolated from males of the moth Agrotis ipsilon and deposited in the GenBank database under the accession number KT944662...

Oestrous signs affect timely mating and reproductive efficiency in swine breeding herds. To study the genetic difference of oestrous signs between Chinese and European pigs, 100 Landrace-Large White (LLW) cross gilts and 50 Chinese Mi gilts were assessed for oestrous signs and the concentrations of serum estradiol-17β and progesterone were determined. The genotype of 39 single nucleotide polymorphisms (SNPs) in 11 oestrogen metabolism and function-related genes was determined by Sequenom iPLEX platform. Compared with LLW gilts, Mi gilts had longer time of standing reflex (p < ...

PURPOSE: Breast cancer (BC) is the most common malignancy among women, while isolated operable liver metastases (LMs) from BC are very rare and occur in only 1-5% of the patients. Besides, positive steroid receptor (SR) status for oestrogen and/or progesterone is known as a factor which improves disease free survival (DFS) and overall survival (OS). The primary aim of this study was to examine the impact of SR status on DFS and OS after liver metastasectomy in female patients with primary BC...
