The onset of puberty in the bull is regulated by the timing of early GnRH pulsatility release from the hypothalamus, which has been demonstrated to be affected by plane of nutrition during calf-hood. The aim of this study was to determine the effect of plane of nutrition on growth rate, scrotal development, metabolite concentrations and exogenous gonadotrophin (GnRH) induced release of luteinizing hormone (LH), follicle stimulating hormone (FSH) and testosterone (TT) in pre-pubertal bulls of two contrasting dairy breeds...

Cancer cachexia is a progressive wasting syndrome characterized by anorexia and weight loss, specifically muscle wasting and fat depletion. There is no therapeutic agent for treatment of this syndrome. We investigated the anti-cachexia effects of Z-505 hydrochloride (Z-505), a new oral growth hormone secretagogue receptor 1a (GHSR1a) agonist, using a mouse model of cancer cachexia. We performed a calcium flux assay in Chinese hamster ovary (CHO-K1) cells stably expressing human GHSR1a to quantify the agonistic activity of Z-505...

Coordination of growth between individual organs and the whole body is essential during development to produce adults with appropriate size and proportions [1, 2]. How local organ-intrinsic signals and nutrient-dependent systemic factors are integrated to generate correctly proportioned organisms under different environmental conditions is poorly understood. In Drosophila, Hippo/Warts signaling functions intrinsically to regulate tissue growth and organ size [3, 4], whereas systemic growth is controlled via antagonistic interactions of the steroid hormone ecdysone and nutrient-dependent insulin/insulin-like growth factor (IGF) (insulin) signaling [2, 5]...

Determination of the role of insulin-like growth factor (IGF) family components in carcinogenesis of several human tumors is based on numerous epidemiological and pre-clinical studies, experiments in vivo and in vitro and on attempts at application of drugs affecting the IGF axis. Investigative hypotheses in original studies were based on biological functions manifested by the entire family of IGF (ligands, receptors, linking proteins, adaptor molecules). In the context of carcinogenesis the most important functions of IGF family involve intensification of proliferation and inhibition of cell apoptosis and effect on cell transformation through synthesis of several regulatory proteins...

OBJECTIVES: To identify endocrinologic problems, particularly those concerning growth, in collodion babies (CBs). METHODS: Clinically identified newborn CBs were included in the study group (group 1). Because CBs are generally born premature, small for gestational age (SGA), or both, a control group matched to the study group in terms of gestational age and birthweight (group 2) was also established. Blood specimens were collected from both groups for thyroid function tests and to measure serum growth hormone (GH), insulinlike growth factor 1 (IGF-1) and IGF binding protein-3 (IGFBP-3) levels...

There is increasing evidence that growth hormone (GH) and insulin-like growth factor 1 (IGF-1) signaling (collectively referred to as somatotropic signaling) during development has a profound influence on aging and longevity. Moreover, the absence of GH action was shown to modify responses of adult mice to calorie restriction (CR) and other antiaging interventions. It was therefore of interest to determine whether GH resistance in GH receptor knockout (GHR-KO) mice would modify the effects of mild pre-weaning CR imposed by increasing the number of pups in a litter (the so-called litter crowding)...

Klotho was first discovered as an aging-suppressor gene. Mice that do not express klotho die prematurely with multiple symptoms of aging, several of which are also characteristic of decreased GH/IGF-1 axis activity. Klotho is highly expressed in the brain, the kidney, and parathyroid and pituitary glands, but can also serve as a circulating hormone by its shedding, forming soluble klotho (sKlotho) that can be detected in blood, cerebrospinal fluid and urine. Several lines of evidence suggest an association between klotho levels and activity of the GH/IHG-1 axis: The GH-secreting cells in the anterior pituitary of klotho-deficient mice are hypotrophic; klotho levels are altered in subjects with pathologies of the GH/IGF-1 axis; and accumulating data indicate that klotho is a direct regulator of GH secretion...

Anorexia nervosa (AN) is characterized by severe undernutrition associated with alterations in multiple endocrine axes, which are primarily adaptive to the state of caloric deprivation. Hormonal changes include growth hormone (GH) resistance with low insulin like growth factor-1 (IGF-1) levels, hypothalamic hypogonadism, relative hypercortisolemia and changes in appetite regulating hormones, including leptin, ghrelin, and peptide YY. These alterations contribute to abnormalities in bone metabolism leading to low bone mass, impaired bone microarchitecture, and increased risk for fracture, and may also negatively impact cognition, emotions and mood...

BACKGROUND: Fanconi anemia (FA) is a condition characterized by genetic instability and short stature, which is due to growth hormone (GH) deficiency in most cases. However, no apparent relationships have been identified between FA complementation group genes and GH. In this study, we thereby considered an association between FA and Laron syndrome (LS) (insulin-like growth factor 1 [IGF-1] deficiency). METHODS: A 21-year-old female Mexican patient with a genetic diagnosis of FA was referred to our research department for an evaluation of her short stature...

Vita Birzniece, P Hugh R Barrett, Ken K Y Ho
CONTEXT: Growth hormone (GH) stimulates hepatic synthesis of very-low-density lipoproteins (VLDL), whereas hepatic steatosis develops as a result of GH deficiency. Steatosis is also a complication of tamoxifen treatment, the cause of which is not known. As tamoxifen inhibits the secretion and action of GH, we hypothesize that it induces steatosis by inhibiting hepatic VLDL export. AIM: To investigate whether tamoxifen reduces hepatic VLDL secretion. DESIGN: Eight healthy, normolipidemic women (age 64...

Apart from being individually associated with cardiometabolic health, 25(OH)D and IGF-1 interplay with a positive correlation between them, which raises questions about the role of vitamin D for the adverse cardiovascular (CV) risk profile in hyposomatotropism. Thus, we aimed to investigate vitamin D status in GH deficiency (GHD) and the association between 25(OH)D and metabolic syndrome (MetS), its components, and other surrogate markers of CV risk. A total of 129 GHD adults (childhood-onset GHD, 41.9%) underwent blood testing (glucose, insulin, lipid profile, uric acid); blood pressure, anthropometric and bioelectrical-impedance measurements...

PURPOSE: Obesity is an established risk factor for renal cell carcinoma (RCC). It is unclear what biologic mechanisms underlie this association, although recent evidence suggests that the effects of circulating hormones such as insulin-like growth factors (IGF) and adipokines may play a role. METHODS: To address this question, we conducted a nested case-control study of RCC (252 cases, 252 controls) within the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial investigating associations with pre-diagnostic serum levels of total adiponectin, high-molecular-weight (HMW) adiponectin, IGF-1, IGF-binding protein-3 (IGFBP-3), and C-peptide...

BACKGROUND: The growth rate often varies among individual broilers of the same breed under a common management condition. To investigate whether a variation in the growth rate is associated with a difference in hormone levels and myogenic gene expression profile in broilers, a feeding trial was conducted with 10,000 newly hatched Ross 308 chicks in a commercial production facility under standard management. At 38 d of age, 30 fast-, 30 medium-, and 30 slow-growing broilers were selected among 600 healthy male individuals...

Type 1 diabetes mellitus (T1DM) is one of the most common chronic diseases diagnosed in childhood. Childhood and adolescent years are also the most important period for growth in height and acquisition of skeletal bone mineral density (BMD). The growth hormone (GH)/insulin like growth factor -1 (IGF-1) axis which regulates growth, is affected by T1DM, with studies showing increased GH and decreased IGF-1 levels in children with T1DM. There is conflicting data as to whether adolescents with TIDM are able to achieve their genetically-determined adult height...

Growth hormone (GH) and insulin like growth factor-1 (IGF-1) are anabolic hormones that facilitate somatic and skeletal growth, and regulate metabolism via endocrine and autocrine/paracrine mechanisms. We hypothesized that excess tissue production of GH will protect skeletal growth and integrity in states of reductions in serum IGF-1 levels. To test our hypothesis we used the bovine GH (bGH) transgenic mice as a model of GH hypersecretion and ablated the liver-derived acid labile subunit (ALS), which stabilizes IGF-1 complexes with IGF-binding protein-3 (IGFBP-3) and -5 in circulation...

BACKGROUND: Cell necrosis, oxidative damage, and fibrogenesis are involved in cirrhosis development, a condition in which insulin-like growth factor 1 (IGF-1) levels are diminished. This study evaluates whether the exogenous administration of low doses of IGF-1 can induce hepatoprotection in acute carbon tetrachloride (CCl4)-induced liver damage compared to healthy controls (Wt Igf (+/+)). Additionally, the impact of IGF-1 deficiency on a damaged liver was investigated in mice with a partial deficit of this hormone (Hz Igf1 (+/-))...

STUDY QUESTION: How does a maternal diabetic hyperadiponectineamia affect signal transduction and lipid metabolism in rabbit preimplantation blastocysts? SUMMARY ANSWER: In a diabetic pregnancy increased levels of adiponectin led to a switch in embryonic metabolism towards a fatty acid-dependent energy metabolism, mainly affecting genes that are responsible for fatty acid uptake and turnover. WHAT IS KNOWN ALREADY: Although studies in cell culture experiments have shown that adiponectin is able to regulate lipid metabolism via 5'-AMP-activated protein kinase (AMPK) and peroxisome proliferator-activated receptor α (PPARα), data on the effects of adiponectin on embryonic lipid metabolism are not available...

BACKGROUND: Yukmijihwangtang (YJT) is a traditional Korean medicine that has been used to treat kidney-yin deficiency symptoms such as dizziness and tinnitus. In addition, because it is also thought to nourish kidney-yin, it has been used to treat short stature from congenital deficiency.

OBJECTIVE: The GH/IGF-1 axis has important roles in growth and metabolism. GH and GH receptor (GHR) are active in the central nervous system (CNS) and are crucial in regulating several aspects of metabolism. In the hypothalamus, there is a high abundance of GH-responsive cells, but the role of GH signaling in hypothalamic neurons is unknown. Previous work has demonstrated that the Ghr gene is highly expressed in LepRb neurons. Given that leptin is a key regulator of energy balance by acting on leptin receptor (LepRb)-expressing neurons, we tested the hypothesis that LepRb neurons represent an important site for GHR signaling to control body homeostasis...
