Human pharmacology of positive GABA-A subtype-selective receptor modulators for the treatment of anxiety.

Acta Pharmacol Sin 2018 Dec 5. Epub 2018 Dec 5.

Centre for Human Drug Research, Leiden, 2333 CL, The Netherlands.

Anxiety disorders arise from disruptions among the highly interconnected circuits that normally serve to process the streams of potentially threatening stimuli. The resulting imbalance among these circuits can cause a fundamental misinterpretation of neural sensory information as threatening and can lead to the inappropriate emotional and behavioral responses observed in anxiety disorders. There is considerable preclinical evidence that the GABAergic system, in general, and its α2- and/or α5-subunit-containing GABA(A) receptor subtypes, in particular, are involved in the pathophysiology of anxiety disorders.

Authors:
John D Fernstrom

Ann Nutr Metab 2018 3;73 Suppl 5:43-52. Epub 2018 Dec 3.

The non-essential amino acid glutamate participates in numerous metabolic pathways in the body. It also performs important physiologic functions, which include a sensory role as one of the basic tastes (as monosodium glutamate [MSG]), and a role in neuronal function as the dominant excitatory neurotransmitter in the central nervous system. Its pleasant taste (as MSG) has led to its inclusion as a flavoring agent in foods for centuries. Read More

Department of Mental Health, Parc Taulí Hospital Universitari, Institut d'Investigació Sanitària Parc Taulí (I3PT), Translational Neuroscience Unit, Universitat Autònoma de Barcelona (UAB), CIBERSAM. Sabadell, Barcelona, Spain. Electronic address:

For many years, the study of the psychotic phenotpe and approach to treatment of schizophrenia has been focused on positive psychotic symptoms, although the functional outcome is more clearly associated with negative and cognitive symptoms. Recently, there has been a growing interest in identifying biomarkers associated with these symptoms at early stages of the illness, including the risk of psychosis in vulnerable individuals (at-risk mental states [ARMS]). In this paper, the role of cortisol and prolactin in the clinical expression of psychosis will be reviewed. Read More

Histone deacetylase inhibitors suppress transdifferentiation of gonadotrophs to prolactin cells and proliferation of prolactin cells induced by diethylstilbestrol in male mouse pituitary.

Histochem Cell Biol 2018 Dec 3. Epub 2018 Dec 3.

Department of Histology and Cell Biology, Nagasaki University Graduate School of Biomedical Sciences, 1-12-4 Sakamoto, Nagasaki, 852-8523, Japan.

Diethylstilbestrol (DES), an estrogen agonist, increases prolactin (PRL) cells through transdifferentiation of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) cells to PRL cells as well as proliferation of PRL cells in adult male mouse pituitary. Since hyperacetylation of histone H3 is implicated in the regulation of activation of various genes, we examined the effect of DES on the state of histone H3 acetylation. DES significantly reduced the immunohistochemical signal for acetylated histone H3 at lysine 9 (H3K9ac) in PRL, LH and FSH cells, but not for H3K18ac or H3K23ac. Read More

Seasonal expressions of luteinising hormone receptor, follicle-stimulating hormone receptor and prolactin receptor in the epididymis of the male wild ground squirrel (Spermophilus dauricus).

Reprod Fertil Dev 2018 Dec 4. Epub 2018 Dec 4.

Luteinising hormone (LH), follicle-stimulating hormone (FSH) and prolactin (PRL) are pituitary-derived hormones and mediate their functions through LH receptor (LHR), FSH receptor (FSHR) and PRL receptor (PRLR) respectively. This study aimed to investigate the seasonal expression patterns of LHR, FSHR and PRLR in the epididymis of the male wild ground squirrel during the breeding and non-breeding seasons. Histologically, principal cells, basal cells, cilia and mature spermatozoa were found in the lumen of caput, corpus and cauda epididymidis in the breeding season, whereas in the non-breeding season, cilia and basal cells were rarely found and the epididymidal duct was devoid of spermatozoa.

Prolactin prevents the kainic acid-induced neuronal loss in the rat hippocampus by inducing prolactin receptor and putatively increasing the VGLUT1 overexpression.

Neurosci Lett 2018 Nov 27. Epub 2018 Nov 27.

Escuela Superior de Medicina, Instituto Politécnico Nacional, Plan de San Luis y Díaz Mirón s/n, Col. Sto. Tomás, 11340, Ciudad de México, Mexico. Electronic address:

Neuroprotective effects of short prolactin (PRL) pre-treatment against kainic acid (KA)-induced damage include neuron loss avoidance in all hippocampal regions and attenuation of seizures. Recent evidence points PRL receptor (PRL-R) as mediator of such neuroprotective effects and seizures as regulators of neuronal marker transcript expression in the hippocampus. Here, we investigated if a daily PRL dose of 100 μg or vehicle for 14 days in ovariectomized rats (OVX) prevents neuron loss induced by KA administered on the third day of PRL treatment in a systemic single dose of 7.

Serum and intratesticular sex steroids in azoospermic men: how do they correlate?

Physiol Res 2018 Nov;67(Supplementum 3):S521-S524

Department of Urology, Military University Hospital Prague, Czech Republic, Institute of Endocrinology, Prague, Czech Republic.

Five intratesticular sex steroids (testosterone, dihydrotestosterone, androstenedione, estradiol and epitestosterone) along with six serum hormones (LH, FSH, prolactin, SHBG, testosterone and estradiol) were determined in 84 non-obstructive azoospermic men, in order to evaluate to what extent serum and testicular tissue as well as individual hormones in the same material mutually correlate. With exception of androstenedione, tight correlations were found among tissue content of sex steroids, while only weak correlation was recorded between serum and testicular concentrations of major sex steroids testosterone and estradiol. It points to importance of measurement of intratesticular steroids in combination with examination of sperm parameters for assessment of testicular function and spermatogenesis. Read More

Dominique Maiter

Neuroendocrinology 2018 Nov 27. Epub 2018 Nov 27.


Dopamine agonists are usually very effective in the treatment of prolactinomas. Nonetheless, a subset of individuals does not respond satisfactorily to these agents and this resistance is characterized by failure to achieve normoprolactinaemia and a 30% or more reduction in maximal tumor diameter (in the case of macroprolactinoma) under maximally tolerated doses. Its overall prevalence is 20-30% for bromocriptine (BRC) and around 10% for cabergoline (CAB). Read More

Stathmin is required for normal mouse mammary gland development and Δ16HER2-driven tumorigenesis.

Cancer Res 2018 Nov 26. Epub 2018 Nov 26.

Molecular Oncology Unit, Centro di Riferimento Oncologico di Aviano (CRO), IRCCS, National Cancer Institute

Post-natal development of the mammary gland relies on the maintenance of oriented cell division and apico-basal polarity, both of which are often deregulated in cancer. The microtubule (MT) network contributes to control these processes, however very little is known about the impact of altered MT dynamics in the development of a complex organ and on the role played by MT-interacting proteins such as stathmin. In this study, we report that female stathmin knock-out (STM KO) mice are unable to nurse their litters due to frank impairment of mammary gland development. Read More

Prolactinomas are the most frequent type of pituitary tumors, which represent 10-20% of all intracranial neoplasms in humans. Prolactinomas develop in mice lacking the prolactin receptor (PRLR), which is a member of the cytokine receptor superfamily that signals via Janus kinase-2-signal transducer and activator of transcription-5 (JAK2-STAT5) or phosphoinositide 3-kinase-Akt (PI3K-Akt) pathways to mediate changes in transcription, differentiation and proliferation. To elucidate the role of the PRLR gene in human prolactinomas, we determined the PRLR sequence in 50 DNA samples (35 leucocyte, 15 tumors) from 46 prolactinoma patients (59% males, 41% females).

Changes in the gills of the European eel (Anguilla anguilla) after chronic exposure to environmental cocaine concentration.

Ecotoxicol Environ Saf 2018 Nov 13;169:112-119. Epub 2018 Nov 13.

Department of Biology, University of Naples Federico II, Via Cinthia, Edificio 7, 80126 Naples, Italy. Electronic address:

The recent discovery of illicit drugs in the aquatic environment has raised concerns about the possible effects on the aquatic fauna, because of the pharmacological activity of these substances. Cocaine is an illicit drug widespread in surface waters since it is the third most widely used drug in North America, Western and Central Europe, and the second in Latin America and the Caribbean. The aim of this study was to evaluate the influence of environmental concentrations of cocaine on the gills of the European eel (Anguilla anguilla). Read More

The Impact of the Opioid Antagonist Naloxone on Experimentally Induced Craving in Nicotine-Dependent Individuals.

Eur Addict Res 2018 13;24(5):255-265. Epub 2018 Nov 13.

Department of Psychiatry and Psychotherapy, University Hospital, LMU Munich, Munich, Germany.

Objective: Preclinical and clinical findings suggest a substantial association of the endogenous opioid system in nicotine dependence. The present study investigates the possible dose-dependent influence of naloxone, an unspecific opioid-receptor-antagonist, combined with cue exposure on the physiological state, locomotor activity, craving and the hypothalamic-pituitary-adrenal axis in nicotine-dependent humans.

Methods: Twenty nicotine-dependent, outpatient participants were deprived of nicotine for over 4 h, before receiving challenges with naloxone (1. Read More

Hormonal Risk Factors for Osteoporosis: Different Profile Among Antipsychotics.

J Child Adolesc Psychopharmacol 2018 Nov 13. Epub 2018 Nov 13.

1 Department of Child and Adolescent Psychiatry, Assistance Publique-Hôpitaux de Paris, University Hospital Pitié-Salpêtrière , Paris, France .

Objectives: Osteoporosis is a major risk factor for fracture and treatment is mainly preventive. Patients with severe psychiatric condition and treated with antipsychotics are at risk for vitamin D deficiency and iatrogenic hyperprolactinemia, two serious risk factors of osteoporosis. We aim to determine whether all antipsychotics are similar regarding the risk of osteoporosis in young patients. Read More

Less known aspects of central hypothyroidism: Part 1 - Acquired etiologies.

J Clin Transl Endocrinol 2018 Dec 26;14:25-33. Epub 2018 Sep 26.

Department of Medical Endocrinology and Metabolism, Rigshospitalet, National University Hospital, Copenhagen University, Copenhagen, Denmark.

Central hypothyroidism (CH) is a rare cause of hypothyroidism. CH is frequently overlooked, as its clinical picture is subtle and includes non-specific symptoms; furthermore, if measurement of TSH alone is used to screen for thyroid function, TSH concentrations can be normal or even above the upper normal reference limit. Indeed, certain patients are at risk of developing CH, such as those with a pituitary adenoma or hypophysitis, those who have been treated for a childhood malignancy, have suffered a head trauma, sub-arachnoid hemorrhage or meningitis, and those who are on drugs capable to reduce TSH secretion.

During pregnancy, the regulation of several neuroendocrine systems is altered to support the pregnancy and facilitate the transition to motherhood. These adaptations are organised by the mother's brain and include those that serve to optimise foetal growth, protect the foetus(es) from adverse prenatal programming by maternal stress, facilitate timely parturition and ensure the offspring are nourished and cared for after birth. Although pregnancy hormones are important in inducing and maintaining many of these adaptations, their effects are often mediated via interactions with neuropeptide systems in the brain. Read More
