  1. 11. Importance of insulin-like growth factor-1 receptor and EWS/FLI-1 fusion protein in growth and survival of two different types of neuroectodermal tumor cells

    Author : Min Wang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Treatment with comparatively low doses of the 3-hydroxy-3-metylglutaryl coenzyme A (HMG-CoA) reductase inhibitor lovastatin caused growth arrest in both melanoma cells and Ewing's sarcoma (ES) cells. In melanoma cells growth inhibition was correlated with a drastic decrease in N-linked glycosylation of the insulin-like growth factor-1 receptor (IGF-1R), which in turn was followed by a decreased expression of IGF-1 binding sites at the cell surface.

  2. 12. GH Secretion in children. Methodological aspects of determining immunoreactive and bioactive isoforms

    Author : Chatarina Löfqvist; Göteborgs universitet; []
    Keywords : Growth hormone; immunoassay; cross-reactivity; standard; antibody; insulin-like growth factor 1; reference values;

    Abstract : A child's hormone-dependent growth is dependent on multiple factors, although linear growth is closely associated with levels of growth hormone (GH) secretion. As GH in serum exists in several isoforms, some of which may not be identified by immunoassay, possible alterations in the secretion of these different isoforms in childhood may influence growth and/or metabolism.

  3. 13. Adolescent type 1 diabetes : Eating and gastrointestinal function

    Author : Maria Lodefalk; Peter Bang; Jan Åman; Hans-Jacob Bangstad; Sweden Stockholm Karolinska institutet; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; type 1 diabetes; adolescence; food habits; gastrointestinal symptoms; incretins; ghrelin; eating disorders; gastric emptying; postprandial glycaemia; Pediatrik; Pediatrics;

    Abstract : Adolescents with type 1 diabetes (T1DM) are given nutritional education, but the knowledge about their adherence to the food recommendations and associations between dietary intake and metabolic control is poor. Gastrointestinal symptoms are more prevalent in adults with T1DM than in healthy controls, which may be due to disturbed gastrointestinal motility. READ MORE

  4. 14. New neurons and astrocytes in the adult brain. Studies on adult rat neural progenitors in vivo and in vitro with special reference to the effects of IGF-I and CNTF regarding proliferation and lineage determination

    Author : Maria A I Åberg; Göteborgs universitet; []
    Keywords : Brain; hippocampus; rat; neurogenesis; progenitor cell; stem cell; ciliary neurotrophic factor; insulin-like growth factor-I; PI3-K; MAPK.;

    Abstract : The hippocampal dentate gyrus in several species, including man, continues to produce new neurons and glial cells in adulthood. The generation of new neurons and glial cells in the adult hippocampus is under strict regulation. Two major events of significance for cell genesis from progenitor cells are proliferation and lineage determination. READ MORE

  5. 15. The expression and function of protein kinase C isoforms in differentiating neuroblastoma cells

    Author : Sofia Fagerström; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neurophysiology; neuropsychology; Neurology; p130cas; PKC; fte-1; neuroblastoma; SH-SY5Y cells; growth cones; neuronal differentiation; neuropsykologi; neurofysiologi;

    Abstract : The human neuroblastoma cell line SH-SY5Y can be induced to differentiate into a neuronal sympathetic phenotype after treatment with 16 nM 12-O-tetradecanoyl phorbol 13-acetate (TPA) in serum, or by a combination of the growth factors basic fibroblast growth factor and insulin-like growth factor-I (bFGF/IGF-I). SH-SY5Y cells stably transfected with TrkA, the nerve growth factor (NGF) receptor, differentiate in response to NGF. READ MORE
