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.

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

Rationale: There are many psychotropic drugs available for treatment of schizophrenia. The clinician's choice of the most effective first-line antipsychotic treatment for patients with schizophrenia should balance considerations of differential efficacy of antipsychotics against the relative risk of different side effects.
Method: We reviewed recent studies using meta-analytic techniques and additional studies of new antipsychotics which quantitatively evaluate the efficacy of side effects of first- and second-generation antipsychotics and studies of the efficacy on add-on secondary medications. Read More

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

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

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.

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.

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

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).

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
