Patients with active Cushing's syndrome (CS) exhibit an increase of the visceral adipose tissue, increasing the risk of cardiovascular events. Until now, it is not yet clear whether remission of CS leads to a normalization of body composition, or if different strategies to control hypercortisolism could result in a different clinical outcome concerning adipose tissue distribution. Therefore, we analyzed body composition changes using dual-energy X-ray absorptiometry (DXA) in patients with CS in a prospective and controlled study...

PGRMC1 is known to be highly expressed in breast cancer tissue and is associated with chemoresistance in breast cancer cells. However, its role in breast cancer signaling is not fully understood yet. In the present study, the expression status of PGRMC1 and its phosphorylated version (pPGRMC1) in breast cancer tissue and surrounding stroma before and after neoadjuvant therapy was examined to find a possible association to therapy response. Tissue biopsies of 69 breast cancer patients were analyzed by immunohistochemistry for expression levels of PGRMC1 and pPGRMC1...

Obesity has increased dramatically worldwide, which is associated with male infertility. Androgen deficiency, impaired spermatogenesis, and erectile dysfunction are characteristics of male infertility. The balance of androgens and estrogens is essential for maintaining normal reproductive function in males. Aromatase, the rate-limiting enzyme in the conversion of androgens into estrogens, is present in various tissues. The expression of aromatase is proportional to body fat mass and causes more fat accumulation, thus forming a vicious cycle...

The association between a low-carbohydrate diet (LCD) score and the risk of diabetes mellitus (DM) is contradictory. This study is a systemic review of cohort studies that have focused on the association between the LCD score and DM. We searched PubMed/Medline, Scopus, Embase, ISI Web of Science, and Google Scholar for papers published through January 2017 with no language restrictions. Cohort studies that reported relative risks (RRs) with 95% confidence intervals (CI) for DM were included. Finally, 4 studies were considered for our meta-analysis...

Sclerostin inhibits Wnt/β-catenin signaling pathway, thereby decreasing bone formation. Osteoblast stimulating actions of parathyroid hormone (PTH) are mediated by suppression of sclerostin. Thus, sclerostin may reflect both bone metabolism and parathyroid function. The study was aimed to analyze the patterns of the changes of mineral and bone biomarkers for 9 months following kidney transplantation (KTx). Thirty-five patients after KTx were included into a 9-month observational study. Serum creatinine, calcium, phosphorus, 25-OH vitamin D, PTH, fibroblast growth factor 23 (FGF-23), sclerostin, and bone-specific alkaline phosphatase (BAP) were measured before KTx, and 1, 2 weeks, and 1, 2, 3, 4, 5, 6, and 9 months thereafter...

Despite recent comprehensive genetic analyses, molecular evidence for a pathophysiological continuum linking benign adrenocortical adenoma (ACA) and highly aggressive adrenocortical carcinoma (ACC) is still elusive. Using human tumor samples and the established ACC cell line SW-13, this study investigated potential regulatory roles for FOXO transcription factors, in modulating adrenocortical tumorigenesis. Adrenocortical tumor specimens (20 ACAs, 10 ACCs, and 9 normal adrenal tissue samples) obtained from 30 patients were analyzed for ubiquitously expressed FOXO transcription factors, FOXO1 and FOXO3 using qRT-PCR and immunohistochemistry...

The aim of this study was to assess the impact of dietary control on VLDL1- and VLDL2-TG kinetics and associated metabolic parameters. Twelve overweight/obese men were randomized to a provided 3 day isocaloric diet with fixed macronutrient composition (diet group, n=6) or to their regular unrestricted diet (non-diet group, n=6). VLDL1- and VLDL2-TG turnovers were measured twice 2-4 weeks apart, using primed-constant infusion of ex vivo labeled [1-(14)C]VLDL1-TG and [9,10-(3)H]VLDL2-TG. Isocaloric diet intervention lowered the difference in the mean of both VLDL2-TG secretion and clearance rate (p<0...

Epicardial adipose tissue (EAT) is an easily measurable visceral fat of the heart with unique anatomy, functionality, and transcriptome. EAT can serve as a therapeutic target for pharmaceutical agents targeting the fat. Glucagon-like peptide-1 (GLP-1) and GLP-2 analogues are newer drugs showing beneficial cardiovascular and metabolic effects. Whether EAT expresses GLP- 1 and 2 receptors (GLP-1R and GLP-2R) is unknown. RNA-seq analysis and quantitative real-time polymerase chain reaction (qRT-PCR) were performed to evaluate the presence of GLP-1R and GLP-2R in EAT and subcutaneous fat (SAT) obtained from 8 subjects with coronary artery disease and type 2 diabetes mellitus undergoing elective cardiac surgery...

17β-Estradiol is known to regulate energy metabolism and body weight. Ovariectomy results in body weight gain while estradiol administration results in a reversal of weight gain. Isoflavones, found in rodent chow, can mimic estrogenic effects making it crucial to understand the role of these compounds on metabolic regulation. The goal of this study is to examine the effect of dietary isoflavones on body weight regulation in the ovariectomized rat. This study will examine how dietary isoflavones can interact with estradiol treatment to affect body weight...

The thyroid functions as a regulator of cardiac function and rhythm through genomic and nongenomic actions of triiodothyronine (T3) in cardiac myocytes. Atrial fibrillation is a common complication of thyrotoxicosis. Hypothyroidism is not considered a risk factor for arrhythmias despite well-known EKG changes in this condition. This case control study was conducted to analyze the differences, if any, in the prevalence of cardiac arrhythmias between hypothyroid patients and euthyroid controls. Three hundred and four consecutive patients admitted at our medical center for a period of one year were included in the study...

There is scarce data on the clinical utility of volume measurement for growth hormone (GH)-secreting pituitary adenomas. The current study objective was to assess the association between pituitary adenoma volumes and baseline endocrine evaluation, initial surgical success rate, and disease control among patients with acromegaly. A retrospective cohort study was conducted at a clinical research center including patients with acromegaly due to GH-secreting pituitary adenomas. Baseline hormonal evaluation and adenoma characteristics according to MRI were collected...

Insulinomas are rare pancreatic neuroendocrine tumors. The genetic causes underlying insulinoma are still being investigated. Recently, 3 independent studies reported a recurrent somatic mutation in YY1 gene (C>G; Thr372Arg) among insulinoma patients belonging to Chinese and Western Caucasian populations, which was found to increase insulin secretion by β-cells. However, the status of this key gene variation remains unknown in patients of other ethnicities. We, therefore, screened Indian sporadic insulinoma patients for YY1 T372R mutation in the present study...

Insulin resistance is the underlying mechanism for the metabolic syndrome and associated dyslipidaemia that theoretically implies a practical tool for identifying individuals at risk for cardiovascular disease and type-2-diabetes. Another screening tool is the hypertriglyceremic-waist phenotype (HTW). There is important impact of the ethnic background but a lack of studied European populations for the association of the triglyceride/high-density lipoprotein cholesterol (HDL-C) ratio and insulin resistance. This observational, retrospective study evaluated lipid ratios and the HTW for predicting the metabolic syndrome/insulin resistance in 1932 non-diabetic individuals from Germany in the fasting state and during a glucose tolerance test...

Obesity appears to be associated with female reproductive dysfunction and infertility. Women with obesity undergoing in vitro fertilization (IVF) had poor oocyte quality, decreased embryo development, and poor pregnancy outcome. However, the mechanism linking obesity to poor reproductive outcomes is still unclear. Obesity is frequently accompanied with elevated leptin levels. Here we aimed to evaluate the effect of high leptin level in follicular fluid (FF) on the proliferation and apoptosis in granule cells and correlate these findings with poor reproductive outcomes in infertile women with overweight or obesity who underwent IVF treatment...
