OBJECTIVE: Insulin resistance (IR) is a common disorder, which can impair female fertility and is characterized by phenotypic heterogeneity. Life-style treatment and insulin sensitizers are commonly used in the management of women with IR and consequent hyperinsulinemia, in order to restore the normal endocrinological and clinical parameters. Metformin (MET) is considered one of the first approaches to this pathology but new evidences are showing promising results using myo-inositol (MYO) in the management of this pathology...

Ying Liang, Xin Yu
BACKGROUND: Effective management strategies for the negative symptoms of schizophrenia remain an unmet need, and data on the use of antipsychotics in this population are scarce, particularly in Chinese patients. Therefore, we investigated amisulpride for the treatment of Chinese patients with predominantly negative symptoms of schizophrenia. METHODS: This post hoc subanalysis of the prospective Effectiveness and Safety of Amisulpride in Chinese Patients with Schizophrenia (ESCAPE) study included adult Chinese patients with an International Classification of Diseases-10 diagnosis of schizophrenia and predominantly negative symptoms, who received amisulpride for 8 weeks...

PURPOSE: Dopamine agonist (DA) therapy is recommended as the first-line treatment for prolactinomas. However, it requires long treatment duration, and a high recurrence rate after DA withdrawal has been reported. We aimed to elucidate the predictors for long-term remission following DA withdrawal and propose the best candidates who can achieve complete remission after DA withdrawal. METHODS: In a retrospective cohort study, we included 89 patients with prolactinoma who have withdrawn DAs with normal prolactin (PRL) levels at Seoul National University Hospital, from 2000 to 2016...

The MEN1 gene, which encodes the protein Menin, was investigated for its regulatory role in milk protein synthesis in mammary glands. Menin responds to nutrient and hormone levels via the PI3K/Akt/mTOR pathway. Bovine mammary epithelial cells and tissues were used as experimental models in this study. The results revealed that the milk protein synthesis capacity of mammary epithelial cells could be regulated by MEN1/Menin. The overexpression of Menin caused significant suppression of factors involved in the mTOR pathway, as well as milk protein κ-casein (CSNK)...

Fetal alcohol exposure (FAE) is known to increase prolactin (PRL) secretion from the pituitary lactotropes. In this study we determined whether microRNAs (miRs) are involved in FAE induced alteration in PRL release. We employed a rat animal model of FAE involving feeding pregnant Fisher 344 rats with a liquid diet containing 6.7% alcohol between gestational day 7 to 21 (AF). Both cyclic and estradiol implanted FAE females showed increased levels of plasma PRL and pituitary PRL mRNA but reduced levels of pituitary dopamine D2 receptor (D2R) and its short spliced form (D2S)...

Context Management of prolactinomas during pregnancy has always been a challenge. There is a concern about the risk of tumor growth, as well as the effects of the treatment on the developing fetus. Another issue that has been less studied is the outcome of women with prolactinoma after pregnancy and lactation. Objectives To evaluate remission of hyperprolactinaemia after pregnancy and lactation in women with prolactinoma. To describe the safety of dopamine agonists for the fetus and pregnancy outcomes. Methods A retrospective study of 32 pregnancies in women with prolactinoma was conducted in a single-centre...

Animal studies have linked the estrogenic properties of bisphenol A (BPA) to adverse effects on the endocrine system. Because of concerns for similar effects in humans, there is a desire to replace BPA in consumer products, and a search for BPA replacements that lack endocrine-disrupting bioactivity is ongoing. We used multiple cell-based models, including an established multi-parametric, high throughput microscopy-based platform that incorporates engineered HeLa cell lines with visible ERα- or ERβ-regulated transcription loci, to discriminate the estrogen-like and androgen-like properties of previously uncharacterized substituted bisphenol derivatives and hydroquinone...

BACKGROUND: In the neonatal period, pituitary hormones including prolactin (PRL) and growth hormone (hGH) are secreted in high amounts due to immature feedback mechanisms. As both hormones are secreted in part by the same somatomammotrophic cells, we investigated their relationship in newborns in relation to sex, gestational week, method of delivery and anthropometric data. METHODS: Serum levels of PRL and hGH were measured in blood from 225 newborns. Newborn data were extracted from medical records...

Folliculo-stellate (FS) cells are non-endocrine cells found in the adenohypophysis and are identified in many animals by the S100 protein marker. Although keratin is another FS marker in several animals, there is no information on localization of keratin in the avian adenohypophysis. In this study, localization of cytokeratin in chicken adenohypophyseal cells was investigated immunohistochemically. Basic cytokeratin (bCK)-positive cells were arranged radially in the cell cords with their cytoplasmic processes reaching the basal lamina...

INTRODUCTION: The polypeptide hormone prolactin (PRL) represents the pituitary modulator of lactation and reproduction. Currently, we discuss the wide range of PRL actions "beyond the mammary horizon". Multiple studies had showed the role of PRL as a cytokine, with comparable structural motifs, similar receptor structures and signal transduction pathways. Almost two decades ago it was fi rst hypothesized that PRL acts as a neuroendocrine modulator of both skin epithelial growth and the skin immune system...

Elephant ovaries contain multiple corpora lutea (CLs) throughout pregnancy. Two CLs (P-1 and P-2) collected from a pregnant African elephant were used to investigate their origin and physiological state in this study. The mRNA expressions of prolactin receptor, CYP11A and inhibin betaB subunit were higher in P-2 than in P-1, while LHCGR and inhibin betaA subunit mRNA were higher in P-1 than in P-2. Protein expression of cleaved caspase-3 was detected in P-1 but not in P-2. These results suggest different origins for the two CLs in this one pregnant elephant, and we also demonstrated the production of bioactive prolactin by the elephant placenta...
