    Altered structure and function of adipose tissue in long-lived mice with growth hormone-related mutations.
    Adipocyte 2017 Mar 21:1-7. Epub 2017 Mar 21.
    a Department of Internal Medicine , Southern Illinois University School of Medicine , Springfield , Illinois , USA.
    A major focus of biogerontology is elucidating the role(s) of the endocrine system in aging and the accumulation of age-related diseases. Endocrine control of mammalian longevity was first reported in Ames dwarf (Prop1(df)) mice, which are long-lived due to a recessive Prop1 loss-of-function mutation resulting in deficiency of growth hormone (GH), thyroid-stimulating hormone, and prolactin. Following this report, several other GH-related mutants with altered longevity have been described including long-lived Snell dwarf and growth hormone receptor knockout mice, and short-lived GH overexpressing transgenic mice.

    Cooperative Synthesis of Dopamine in Rat Mediobasal Hypothalamus as a Compensatory Mechanism in Hyperprolactinemia.
    Biochemistry (Mosc) 2017 Mar;82(3):366-372
    Koltzov Institute of Developmental Biology, Russian Academy of Sciences, Moscow, 119334, Russia.
    Dopamine (DA), synthesized in the mediobasal hypothalamus by dopaminergic neurons containing two enzymes of DA synthesis - tyrosine hydroxylase and decarboxylase of aromatic L-amino acids, or by monoenzymatic non-dopaminergic neurons containing one DA synthesis enzyme in cooperation, is known to have an inhibitory effect on prolactin secretion. Deterioration of this inhibitory control leads to an increase in prolactin concentration in the blood and to the development of hyperprolactinemia syndrome. In a rat model of hyperprolactinemia induced by administration of a neurotoxin causing degeneration of dopaminergic and noradrenergic neurons, the level of DA first decreases, leading to an increase in prolactin level (decompensation stage), while later both levels are restored to normal (compensation stage).

    Methods: Sex hormone levels were measured in fasting blood samples from male patients with SLE (n = 71) and those with SSc (n = 29) and compared to those population-based, age-matched male controls. Read More

    Testosterone replacement therapy: role of pituitary and thyroid in diagnosis and treatment.
    Transl Androl Urol 2016 Dec;5(6):850-858
    Department of Endocrinology, Diabetes and Metabolism, Cleveland Clinic, Cleveland, OH, USA.
    Crosstalk among hormones characterizes endocrine function, and assessment of the hypogonadal man should take that into consideration. In men for whom testosterone deficiency is a concern, initial evaluation should include a thorough history and physical exam in which other endocrinopathies are being considered. Hypogonadism can be associated with both pituitary and thyroid dysfunction, for which appropriate biochemical evaluation should be undertaken in certain clinical scenarios. Read More

    Nitric Oxide Plays a Key Role in Ovariectomy-Induced Apoptosis in Anterior Pituitary: Interplay between Nitric Oxide Pathway and Estrogen.
    PLoS One 2016 9;11(9):e0162455. Epub 2016 Sep 9.
    Departamento de Química Biológica, IQUIFIB, Facultad de Farmacia y Bioquímica, Universidad de Buenos Aires, Buenos Aires, Argentina.
    Changes in the estrogenic status produce deep changes in pituitary physiology, mainly because estrogens (E2) are one of the main regulators of pituitary cell population. Also, E2 negatively regulate pituitary neuronal nitric oxide synthase (nNOS) activity and expression and may thereby modulate the production of nitric oxide (NO), an important regulator of cell death and survival. Little is known about how ovary ablation affects anterior pituitary cell remodelling and molecular mechanisms that regulate this process have not yet been elucidated. Read More

    Unexpected severe consequences of Pikfyve deletion by aP2- or Aq-promoter-driven Cre expression for glucose homeostasis and mammary gland development.
    Physiol Rep 2016 Jun;4(11)
    Department of Physiology, Wayne State University School of Medicine, Detroit, Michigan
    Systemic deficiency of PIKfyve, the evolutionarily conserved phosphoinositide kinase synthesizing cellular PtdIns5P and PtdIns(3,5)P2 and implicated in insulin signaling, causes early embryonic death in mice. In contrast, mice with muscle-specific Pikfyve disruption have normal lifespan but exhibit early-age whole-body glucose intolerance and muscle insulin resistance, thus establishing the key role of muscle PIKfyve in glucose homeostasis. Fat and muscle tissues control postprandial glucose clearance through different mechanisms, raising questions as to whether adipose Pikfyve disruption will also trigger whole-body metabolic abnormalities, and if so, what the mechanism might be.

    Original Research: Metabolic alterations from early life thyroxine replacement therapy in male Ames dwarf mice are transient.
    Exp Biol Med (Maywood) 2016 Oct 13;241(16):1764-71. Epub 2016 May 13.
    Department of Internal Medicine, Geriatrics Research, Southern Illinois University School of Medicine, Springfield, IL 62794, USA.
    Ames dwarf mice are exceptionally long-lived due to a Prop1 loss of function mutation resulting in deficiency of growth hormone, thyroid-stimulating hormone and prolactin. Deficiency in thyroid-stimulating hormone and growth hormone leads to greatly reduced levels of circulating thyroid hormones and insulin-like growth factor 1, as well as a reduction in insulin secretion. Early life growth hormone replacement therapy in Ames dwarf mice significantly shortens their longevity, while early life thyroxine (T4) replacement therapy does not. Read More

    Neurobiol Aging 2016 Apr 6;40:22-40. Epub 2016 Jan 6.
    Department of Basic Sciences, University of North Dakota School of Medicine and Health Sciences, Grand Forks, ND, USA. Electronic address:
    APP/PS1 double transgenic mice expressing human mutant amyloid precursor protein (APP) and presenilin-1 (PS1) demonstrate robust brain amyloid beta (Aβ) peptide containing plaque deposition, increased markers of oxidative stress, behavioral dysfunction, and proinflammatory gliosis. On the other hand, lack of growth hormone, prolactin, and thyroid-stimulating hormone due to a recessive mutation in the Prop 1 gene (Prop1df) in Ames dwarf mice results in a phenotype characterized by potentiated antioxidant mechanisms, improved learning and memory, and significantly increased longevity in homozygous mice. Based on this, we hypothesized that a similar hormone deficiency might attenuate disease changes in the brains of APP/PS1 mice. Read More

    [Sheehan's syndrome--a forgotten disease with 100 years' history].
    Przegl Lek 2015 ;72(6):313-20
    Although named after Harold Sheehan, postpartum ischemic pituitary necrosis was reported for the first time 100 years ago in Przeglad Lekarski by Leon Konrad Gliński. In the majority of cases, the syndrome is a consequence of severe postpartum bleeding episode resulting in severe hypotension or hemorrhagic shock. The frequency of Sheehan's syndrome has decreased in developed countries as a result of improved obstetrical care, but this clinical entity remains a common cause of hypopituitarism in developing countries.

    POU1F1, a pituitary-specific POU-homeo domain transcription factor, plays an essential role in the specification of the somatotroph, lactotroph and thyrotroph lineages and in the activation of GH1, PRL and TSHβ transcription. Individuals with mutations in POU1F1 present with combined deficiency of GH, PRL and TSH. Here, we identified a heterozygous missense mutation with evidence of pathogenicity, at the POU1F1 locus, in a large family in which an isolated growth hormone deficiency segregates as an autosomal dominant trait.

    a Department of Internal Medicine , Clinical Immunology and Allergy Unit, Antalya Training and Research Hospital , Antalya , Turkey.
    Context: Netherton syndrome (NS) is associated with the mutation in the SPINK5 gene, which codes LEKTI (lymphoepithelial Kazaltype related inhibitor), a serine protease inhibitor. As a result of aging coupled with immune deficiency, clinical symptoms may vary.

    Methods: The patient was presented to our clinic with sparse and brittle hair along with pruritic, erythematous and scaling cutaneous lesions. Read More

    Suppressor of cytokine signaling 2 (SOCS2) deletion protects against multiple low dose streptozotocin-induced type 1 diabetes in adult male mice.
    Horm Mol Biol Clin Investig 2016 Apr;26(1):67-76
    Background: Diabetes type 1 is characterized by the failure of beta cells to produce insulin. Suppressor of cytokine signaling (SOCS) proteins are important regulators of the Janus kinase/signal transducer and activator of transcription (JAK-STAT) pathway. Previous studies have shown that GH can prevent the development of type I diabetes in mice and that SOCS2 deficiency mimics a state of increased GH sensitivity. Read More

    The role of prolactin in andrology: what is new?

    Sexual Medicine and Andrology Unit, Department of Experimental and Clinical Biomedical Sciences, University of Florence, Viale Pieraccini, 6, 50139, Florence, Italy.
    Prolactin (PRL) has been long deemed as a hormone involved only in female reproduction. However, PRL is a surprising hormone and, since its identification in the 1970s, its attributed functions have greatly increased. However, its specific role in male health is still widely unknown. Read More

    [A Novel Clinical Entity "Anti-PIT-1 Antibody Syndrome"--Autoimmunity against a Transcription Factor].
    Rinsho Byori 2015 Apr;63(4):491-7
    Autoimmunity against the pituitary has been observed in patients with hypophysitis. Although various autoantibodies against pituitary proteins have been reported, it is known that most of them are markers for the disease. Recently, a unique autoantibody against pituitary transcription factor PIT-1 (POU1F1) was detected in patients with an acquired combined pituitary hormone deficiency characterized by a specific defect in growth hormone (GH), prolactin (PRL), and thyroid-stimulating hormone (TSH).

    Target Prolactin Range in Treatment of Tetrahydrobiopterin Deficiency.
    J Pediatr 2016 Jan 27;168:236-9.e1. Epub 2015 Oct 27.
    Department of Pediatrics, University of Torino, Torino, Italy.
    The introduction of dopamine agonists for treating tetrahydrobiopterin deficiency imposes the evaluation of peripheral prolactin as the sole reliable biochemical marker of dopaminergic homeostasis. Here we provide the clinical interpretation of the previously described short prolactin profile, based on the longitudinal monitoring of 8 patients with tetrahydrobiopterin deficiency. Read More

    Heat Shock Factor 1 Deficiency Affects Systemic Body Temperature Regulation.
    Neuroendocrinology 2016 30;103(5):605-15. Epub 2015 Oct 30.
    Introduction: Heat shock factor 1 (HSF1) is a ubiquitous heat-sensitive transcription factor that mediates heat shock protein transcription in response to cellular stress, such as increased temperature, in order to protect the organism against misfolded proteins. In this study, we analysed the effect of HSF1 deficiency on core body temperature regulation.

    Materials And Methods: Body temperature, locomotor activity, and food consumption of wild-type mice and HSF1-deficient mice were recorded. Read More
