G-Protein Coupled Receptors Modulating Incretin Hormone Secretion
The incretin hormones glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), secreted from K-cells and L-cells respectively, augment insulin secretion. In addition, GIP facilitates triglyceride storage and GLP-1 has anorexic effects. Incretins are released from the …

Mechanisms underlying monosaccharide stimulated incretin hormone secretion from the intestine
… prevalence worldwide. Drugs which mimic the gut hormone glucagon-like peptide-1 (GLP-1), e.g. Semaglutide, are currently the most effective obesity and T2D therapeutics, activating GLP-1 receptors in the pancreas and brain to improve blood glucose and appetite control. Due to the therapeutic …

Calcium and growth hormone secretion in the domestic fowl (Gallus domesticus)
… required for secretagogue induced growth hormone release from somatotroph cells of the chicken anterior pituitary. Growth hormone release can be induced via different intracellular pathways and these in turn can act to produce a synergistic hormone release. This thesis sought to further …

The Effects of Vasoactive Intestinal Peptide on Adrenal Steroid Hormone Secretion
… We have studied the effects of VIP on steroid hormone secretion from the outer zones of the normal rat adrenal cortex. Intact capsule-glomerulosa preparations, consisting of the capsule, zona glomerulosa, and a small portion of the zona fasciculata were perifused in vitro. The secretory …

Exocytosis in Type 2 Diabetes- Functional and genetic studies of hormone secretion
… by dysregulated beta-and alpha-cell hormone secretion leading to elevated blood glucose levels. Several proteins are crucial in maintaining exocytosis of the hormone-containing granules such as Syntaxin1A (Stx1A), SNAP25, Munc-18 (Stxbp1) and the family of Synaptotagmins (Syts). The …

The Effect of Yoga on Growth Hormone Secretion in Young Men and Women
… effects of an acute bout of yoga exercise on the secretion of growth hormone (GH) in healthy, young males and females. <strong>METHODS</strong> Seventeen participants (mean age 23.9 ± 3.9) were volunteered and completed the university IRB approved study. Participants completed a 60-min, certified …

The Free Fatty Acid Receptor GPR40 - expression and role in islet hormone secretion
… islets. A similarly increased glucagon secretion from alpha-cells was demonstrated after we established that these cells also express GPR40. Antisense knock-down of GPR40 abolished the effect of FFA stimulation on hormone secretion from both cell types. In the final part of this work, …

Applications of a radioimmunoassay technique to the study of luteinizing hormone secretion in the rat
… The assay system was applied to the study of LH secretion in rats under both normal and experimentally manipulated conditions. Particular attention was focussed upon comparison of circulating LH levels in conscious, unstressed animals with those in anaesthetized animals, with or without surgical …

The Effect of Feeding, Bilateral Parotidectomy, and Pilocarpine Treatment on Parotid Hormone Secretion in the Pig
… olfactory, and masticatory stimuli on parotid hormone (PH) secretion is reported. Feeding a regular chow was shown to be a potent stimulus for PH secretion. The parotid endocrine system is highly sensitive to the eating stimulus, since a period of feeding lasting 30 sec is enough to cause a …

Role of Endogenous Dopamine in Regulation of Anterior Pituitary Hormone Secretion During Early Postpartum and Various Stages of the Estrous Cycle in Holstein Cows
… FLU), in modulation of gonadotropin, growth hormone (GH) and prolactin (PRL) secretion during the early postpartum period and various stages of the estrous cycle was investigated in Holstein cows. Experiment 1 was conducted in anovulatory early postpartum cows. Fluphenazine caused a decrease …

The metabolic sequelae of oesophago-gastric resection
… symptoms. By profiling and challenging the gut hormone axis in healthy volunteers and patients who had undergone total or subtotal gastrectomy, or oesophagectomy, this thesis explores the possible causative mechanisms for the challenges faced by this patient population. In the surgical groups, …

Molecular biology and biochemistry of brain tumours
… able to induce mitosis of rat gliomas as well as hormone secretion by the anterior pituitary, via the CCK-B receptor. The significance of a polymorphism in the growth hormone releasing hormone (GHRH) receptor (GHRH-R) gene was also determined. Finally, defects in the ß-catenin gene, an important …

Somatostatin Receptor 2 Regulation By C-Terminal Motifs and Pdz Domain Proteins
… main medical approach to controlling excessive hormone secretion from neuroendocrine tumors. Activation of sst2 decreases hormone secretion by inhibiting cAMP production and decreasing intracellular calcium concentrations. In addition, treatment with somatostatin analogs has been shown to …
