Increasing evidence has recently accumulated suggesting that IGF1 system is involved in the regulation of longevity. While in animal models alterations of IGF1 signalling increase life expectancy, in humans there are contradictory data. Centenarians are an extraordinary model to study human longevity, however, they present a number of drawbacks: rarity, frailty due to extreme age and lack of a control group of the same age. The availability of an age-matched control group is c...

Ninety percent of patients had multiple pituitary hormone deficiencies whic...

Purpose: Individuals with mood disorders and schizophrenia (SCZ) exhibit altered function of the HPA axis in response to stress. The glucocorticoid receptor (GR) plays an important role in negative feedback regulation of the HPA-axis. There are two protein isoforms, GRα and GRβ, which have activating and blocking activity respectively. In line with aberrant expression of GR mRNA in the brains of depressed, SCZ and bipolar (BD) patients (1), lymphocytes of depressed, ...

Background: Rats on a free-choice (fc) diet of saturated fat and liquid sugar in addition to chow (fcHFHS) overeat persistently, and show increased hypothalamic neuropeptide Y and decreased melanocortin signaling, which reflects a hunger state despite hyperphagia. This response is specific for a fcHFHS diet, because when given the choice between fat and chow (fcHF) or between liquid sugar and chow (fcHS) hyperphagia is not observed. Because leptin signaling is important for th...

During fasting neuropeptide Y (NPY) neurons in the mediobasal hypothalamus are activated to increase food intake and to conserve energy. Under conditions of food deprivation, lipid metabolism plays an important role in providing fuel for muscle. We investigated if central NPY affects VLDL-TAG secretion directly via the autonomic nervous system. We measured VLDL-TAG secretion in Wistar rats by an intravenous bolus of tyloxapol to inhibit uptake of triglycerides by peripheral ti...

Introduction: DHEAS is among the most abundant sex steroid products of the adrenal gland. DHEAS levels have been repeatedly associated with cardiovascular disease, but data concerning cerebrovascular disease, especially in women, is lacking. In this study, we aimed to investigate the role of DHEAS in a female population suffering an acute stroke.Patients and methods: We studied 302 consecutive female patients presenting with an acute stroke hospitalized ...

Introduction: TAC3/TACR3 mutations have been reported in normosmic congenital hypogonadotropic hypogonadism (nCHH). In the absence of animal models, studies of human neuroendocrine phenotypes associated with neurokinin B and NK3R receptor dysfunction can help to decipher the pathophysiology of this signaling pathway. Our objective was to characterize novel TACR3 mutations and to analyze neuroendocrine profiles in nCHH patients with TAC3/TACR3 biallelic mut...

Introduction: X-linked adrenoleukodystrophy (X-ALD) is an important cause of primary adrenocortical insufficiency (PAI) in men. It’s characterized by impairment in peroxisomal degradation of very-long-chain-fatty-acids (VLCFA), leading to its accumulation on central nervous system, adrenal cortex and testes.Adrenomyeloneuropathy, the most common phenotype of X-ALD, coexists with PAI in up to 70% cases.Case report: A 28-year-ol...

The currently curative therapy for pancreatic endocrine tumours (PET), accounting for <3% of pancreatic tumors, is complete surgical resection, which is achieved in the minority of cases. Most tumors are diagnosed in a late stage, especially in endocrine-inactive forms, indicating the need for further medical therapy. The serine–threonine protein kinase C (PKC) family plays central regulatory roles in several cellular processes, including cell proliferation. PKC signa...

GH and insulin-like growth factor 1 (IGF1) are known to promote breast carcinogenesis. Breast cancer (BC) incidence in not increased in female acromegalic patients, but mortality is greater as compared to general population. We previously demonstrated that GH/IGF1 excess influences BC response to therapy, possibly accounting for the increased mortality. We indeed showed that GH and IGF1 induce cell proliferation of a BC cell line, the MCF7 cells, providing protection towards t...

Introduction: The concentrations of pituitary hormones in the cerebrospinal fluid (CSF) are much lower that their serum counterpart.Aim: To study the CSF access for pituitary glycoprotein hormones (GPH) in patients with pituitary adenomas (PA).Patients and methods: In 221 cases submitted to transsphenoidal surgery for PA (85 acromegaly – ACM, 92 nonfunctioning pituitary adenomas – NFA, 44 prolactinomas – PRM) the sur...

Introduction: Posttraumatic stress disorder (PTSD) is anxious disorder that occurs following exposure to trauma. In the last two decades, numerous studies showed that dysregulation of hipothalamo–pituitary–adrenal axis (HPAA) is a core feature of the PTSD. Still, results are heterogeneous and often conflicted with one another. Therefore, we conducted strictly controlled study in order to characterize relationship between ACTH and cortisol secretion in patients with c...

Vasopressin acts through G protein-coupled receptors on the cardiovascular and renal system to induce vasoconstriction and antidiuresis. Vasopressin also has important functions within the CNS influencing cognition, olfaction and a range of complex social interactions and behaviours. In addition, vasopressin has been reported in the mammalian retina and here we investigated the location and expression of vasopressin and vasopressin receptors (V1a, V1b, and V2) in the rat retin...

Introduction: Leptin receptors have been identified in many peripheral tissues as well as the CNS including the hippocampus, which is particularly vulnerable in Alzheimer’s disease (AD). Animal data shows that leptin may be implicated in the pathophysiology of AD. The aim of this study was to examine if there is any differences in serum leptin levels between patients with AD and normal controls.Material and methods: Ninety patients with AD and 95 no...

Background: Previous studies reported that direct injection of estrogen (E2) into different hypothalamic nuclei affects food intake, body weight and locomotor activity. We hypothesized that E2 signaling in the hypothalamus regulates glucose metabolism independently of circulating estrogen levels.Methods: We investigated the effects of hypothalamic estrogen administration on basal glucose production as well as on hepatic and peripher...
