Vasomotor symptoms (VMS, or hot flashes) plague millions of reproductive age men and women who have natural or iatrogenic loss of sex steroid production. Many affected individuals are left without treatment options because of contraindications to hormone replacement therapy and the lack of equally effective non-hormonal alternatives. Moreover, development of safer, more effective therapies has been stymied by the lack of an animal model that recapitulates the hot flash phenomenon and enables direct testing of hypotheses regarding the pathophysiology underlying hot flashes...

Peroxiredoxin 3 (PRX3) plays a role as a regulator of the adipocyte mitochondrial function due to its antioxidant activity. We have previously reported the existence of a sexual dimorphism in the mitochondrial oxidative stress status of many rat tissues such as white (WAT) and brown (BAT) adipose tissues. The aim was to elucidate whether sex hormones may play a role in PRX3 expression in the adipose tissues of rats. In in vivo experiments, male and female standard diet fed rats, high fat diet (HFD) fed rats and rosiglitazone-supplemented HFD (HDF+Rsg) fed rats, as well as ovariectomized (OVX) and 17beta-estradiol-supplemented OVX (OVX+E2) female rats were used...

Depression induced by stress is affected by sex, age and hormonal status of the animal and also by duration and type of the stressors. Moreover, higher prevalence of depression and comorbidities in women than men implies the need to include the sex variable in studies on animal models of depression. The present study was therefore initiated to evaluate the effect of sex and ovarian hormones on depression-like phenotypes in mice exposed to a 21-day Chronic Variable Mild Stress (CVMS) paradigm. Adult male, intact female and, ovariectomized (OVX) female mice exposed to CVMS displayed despair behavior, a depression-like phenotype, in all the groups...

PURPOSE: Children from smoking mothers have a higher risk of developing obesity and associated comorbidities later in life. Different experimental models have been used to assess the mechanisms involved with this increased risk. Using a rat model of neonatal nicotine exposure via implantation of osmotic minipumps in lactating dams, we have previously shown marked sexual dimorphisms regarding metabolic and endocrine outcomes in the adult progeny. Considering that more than four thousand substances are found in tobacco smoke besides nicotine, we then studied a rat model of neonatal tobacco smoke exposure: adult male offspring had hyperphagia, obesity, hyperglycemia, hypertriglyceridemia, secondary hyperthyroidism and lower adrenal hormones...

Nonalcoholic fatty liver disease (NAFLD) spans steatosis through nonalcoholic steatohepatis, cirrhosis, and hepatocellular carcinoma (HCC) associated with striking systemic features and excess cardiovascular and liver-related mortality. The pathogenesis of NAFLD is complex and multifactorial. Endocrine derangements are closely linked with dysmetabolic traits. For example, in animal and human studies, female sex is protected from dysmetabolism thanks to young individuals' ability to partition fatty acids towards ketone body production rather than very low density lipoprotein (VLDL)-triacylglycerol, and to sex-specific browning of white adipose tissue...

The difference between men and women is clear even just by looking at an electrocardiogram: females present higher resting heart rate, a shorter QRS complex length and greater corrected QT interval. The development of these differences from pubertal age onward suggests that sexual hormones play a key role, although their effect is far from being completely understood. Different incidences between sexes have been reported for many arrhythmias, both ventricular and supraventricular, and also for sudden cardiac death...

INTRODUCTION: Recent research found gender-related differences in resting-state functional connectivity (rs-FC) measured by functional magnetic resonance imaging (fMRI). To the best of our knowledge, there are no studies examining the differences in rs-FC between men, women, and individuals who report a discrepancy between their anatomical sex and their gender identity, i.e. gender dysphoria (GD). METHODS: To address this important issue, we present the first fMRI study systematically investigating the differences in typical resting-state networks (RSNs) and hormonal treatment effects in 26 male-to-female GD individuals (MtFs) compared with 19 men and 20 women...

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder of reproductive age females, leading to infertility. Despite extensive research, the exact pathophysiology and treatment are lacking. The aim of the current study was to evaluate the direct role of adiponectin either alone or together with luteinizing hormone (LH) on sex hormone synthesis and changes in insulin receptor (IR) in the ovary of dehydroepiandrosterone (DHEA)-treated PCOS-mice. Immunohistochemical study showed decreased expression of adiponectin receptor (AdipoR1) in PCOS-ovary which correlated with increased synthesis of androgen and decreased expression of IR...

INTRODUCTION: Psychological stress is known to cause exacerbation of different skin pathologies including alopecia areata (AA). A hyperactivity of the HPA axis in patients affected by AA (AA-patients) was proposed to be a neuroendocrine response to stress. Still little is known about MSH and cortisol production in AA settings. AIM: The aim of the study was to compare trends in a production of melanocyte-stimulating hormone (MSH) and cortisol in patients with AA-patients and healthy controls...

Female sex is a risk factor for inherited and acquired Long-QT associated Torsade de Pointes (TdP) arrhythmias, and sympathetic discharge is a major factor in triggering TdP in female Long-QT syndrome patients. We used a combined experimental and computational approach to predict 'the perfect storm' of hormone concentration, IKr block, and sympathetic stimulation that induces arrhythmia in females with inherited and acquired Long-QT. More specifically, we developed mathematical models of acquired and inherited Long-QT syndrome in male and female ventricular human myocytes by combining effects of a hormone and a hERG blocker dofetilide or hERG mutations...

It is shown that in the development of stroke observed sex differences, which manifest themselves both clinically and by laboratory parameters. While men have a higher incidence of stroke for most of his life, a woman in a more advanced age have a higher risk for stroke. Sex differences in the development of stroke depend on several factors, including genetic and hormonal changes throughout life. Studies sex differences in the risk of stroke is only in the initial stage, but the first results show that there are differences in neuronal cell death in males and females after experimental ischemic stroke...

BACKGROUND: Depression and anxiety are risk factors for cardiovascular disease, but their relationship to blood pressure (BP) is less clear. Age-related comorbidity and lifestyle factors may confound these relationships. This study aimed to assess the relationships among BP, depression and anxiety symptom scores and self-reported history of depression in young adults. METHOD: Data on 1014 participants aged 20 years from the Western Australian Cohort (Raine) Study were analyzed for cross-sectional associations between clinic BP and Depression, Anxiety, Stress Scale questionnaire scores or a reported history of depression, accounting for relevant confounders...

BACKGROUND: Cyproterone acetate (CA) is an antiandrogenic progestin commonly used in adult transwomen to suppress endogenous androgens, often in combination with estrogens to induce feminization. AIM: To assess the (side) effects and biochemical changes of CA alone and in combination with estrogens in adolescent trans-girls. METHODS: This study was a retrospective analysis of clinical and biochemical data from 27 trans-girls who presented at Tanner stage G4 and were treated with CA monotherapy for at least 6 months (mean = 12 months) and then in combination with incremental doses of estrogens (CA + E; mean = 16 months)...

Cucumber (Cucumis sativus L.) is characterized by its diverse and flexible sexual types. Here, we evaluated the effect of low temperature (LT) exposure on cucumber femaleness under short-day conditions. Shoot apices were subjected to whole-genome bisulfate sequencing (WGBS), mRNA-seq, and sRNA-seq. The results showed that temperature had a substantial and global impact on transposable element (TE)-related small RNA-directed DNA methylation (RdDM) mechanisms, resulting in large amounts of CHH-type cytosine demethylation...

We investigated the effects of juvenile hormone analogue (methoprene) and 20-hydroxyecdysone on female and male reproduction in a nymphalid butterfly, Polygonia c-aureum. This butterfly has a facultative adult diapause controlled by the corpora allata and brain. Methoprene seems to terminate reproductive diapause, although transplantation experiments indicate that the activity of the corpora allata does not affect male mating behavior Endo (Dev Growth Differ 15:1-10, 1973a), suggesting that the brain may be involved in diapause...
