  1. 11. Galanin and NPY in the rodent brain: rapid effects of 17beta-estradiol and possible roles in hippocampal plasticity

    Författare :Susanne Hilke; Elvar Theodorsson; Tomas Hökfelt; Bruce S. McEwen; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sex-hormones; Brain; Neuropeptides; Neurochemistry; Neurokemi;

    Sammanfattning : The neuropeptides galanin and neuropeptide Y (NPY) play an important role in the reproduction of rodents, e.g. by modulating the release of gonadal hormones, the nutritional status by effects on feeding behavior and also by influencing mating behavior. LÄS MER

  3. 12. Expression and Regulation of Neuropeptide Y (NPY) in the Islets of Langerhans

    Författare :Ulrika Myrsén Axcrona; Neuroendokrin cellbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrinology; regulatory peptides; diabetes; glucocorticoids; beta cell; islet hormones; neuropeptide Y; insulin; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : This thesis deals with the expression, localization and regulation of neuropeptide Y (NPY) in the pancreatic islets of Langerhans under normal and experimental conditions. NPY is widely distributed in the mammalian nervous system and belongs to a family of closely related petides also comprising peptide YY (PYY) and pancreatic polypeptide (PP). LÄS MER

  4. 13. LXR regulation of hepatic gene expression and pituitary dependent hormones

    Författare :Pia Kotokorpi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Liver X receptor; growth hormone; gene regulation; metabolism; hepatocyte; hepatic steatosis; species differences;

    Sammanfattning : The liver X receptors (LXRs) are ligand activated transcription factors involved in the regulation of metabolic genes. LXRs are considered potential drug targets to treat metabolic disorders, however, unwanted side effects, as revealed from rodent studies, include increased lipogenesis in the liver and increased plasma triglyceride levels.

  5. 14. Alcohol and the effect on some appetite-regulating hormones in man

    Författare :Jan Calissendorff; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Leptin; ghrelin; octanoylated; PYY3-36; GLP-1; obestatin; alcohol; NPY; IGF-1; IGFBP-1; insulin; glucose; testosterone; cortisol; catecholamines;

    Sammanfattning : Beverage containing alcohol has been used for centuries to stimulate appetite. Ingestion of a moderate amount of alcohol increase energy intake. Regulation of food intake is complex. Several factors cooperate such as neural impulses from sensory organs; sight, smell, gut distension, social setting, memory, current energy status and hormones.

  7. 15. The regulation of renal tubular Na+ transport is dependent on interaction between different hormones

    Författare :Yoshiyuki Ohtomo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Norepinephrine; oc-adrenergic; beta-adrenergic; neuropeptide Y; Na ; K -ATPase activity; C-peptide; ontogeny;

    Sammanfattning : Renal Na+,K+-ATPase (NKA) is of great importance for the regulation of salt metabolism and its activity can be inhibited by several natriuretic hormones. So far, the effect of antinatriuretic factors have been less well studied. LÄS MER
