  2. 1. Involvement of Heparan Sulphate Biosynthesis and Turnover in Cell Proliferation. A Novel Role for Nitric Oxide in Recycling of Heparan Sulphate Proteoglycans

    Author : Katrin Mani; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nitrite.; nitric oxide; growth-inhibition; xyloside; glypican; heparan sulphate; Proteoglycan; glycosaminoglycan; Clinical biology; Klinisk biologi;

    Abstract : The present investigation focuses on the role of HS metabolism in cell proliferation. The effect of the HS priming ß-D-xyloside, 2-(6-hydroxynaphthyl)-O-ß-D-xylopyranoside (Xyl-2-Nap-6-OH) on the proliferation of normal and transformed cells was studied. READ MORE

  4. 2. Glypican-1: Structural and functional analysis of the N-glycosylated human protein

    Author : Wael Awad Abdelhady; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proteoglycans; glypicans; glypican-1; heparan sulphate; N-glycosylation; exostosin-proteins; X-ray crystallography; crystal dehydration; diffraction anisotropy; Small angle X-ray scattering SAXS9; protein spectroscopy;

    Abstract : Glypicans are multifunctional cell surface heparan sulphate proteoglycans co-regulating numerous signalling pathways, and are thereby involved in the control of cellular division, differentiation, and morphogenesis. The heparan sulphate (HS) chains are responsible for many of those biological functions; nevertheless recent studies suggest functional roles for the glypican core proteins in mediating the signalling of various growth factors.

  5. 3. On the binding of growth-promoting polyamines to proteoglycans: Implications for growth-regulation and polycation-mediated gene transfer

    Author : Mattias Belting; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; cationic lipid.; gene transfer; gene therapy; cell growth; polyamine transport; spermine; polyamine; growth-inhibition; heparan sulphate; dermatan sulphate; Proteoglycan; glycosaminoglycan; cytogenetics; Genetik; cytogenetik;

    Abstract : Initial investigations were directed at studying the interaction between polyamines and various glycosaminoglycans (GAGs). The polyamine spermine displayed binding to dermatan sulphate (DS) and heparan sulphate (HS) with similar (Kd, 3.9 x 10-4 M) and higher (Kd, 0.37 x 10-6 M) affinity, respectively, than to DNA.

  6. 4. Circulating proteoglycans and glycosaminoglycans during critical illness

    Author : Axel Nelson; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heparan sulphate; glycocalyx; hyaluronic acid; syndecan; permeability; antimicrobial;

    Abstract : The endothelial glycocalyx is the carbohydrate rich inner layer of the blood vessels. Important components of the glycocalyx are the proteoglycans with their attached glycosaminoglycans. READ MORE

  7. 5. Towards cell replacement therapy in Parkinson’s disease. Proteoglycans and Nogo-A as modulators of axonal growth in midbrain dopaminergic neurons

    Author : Zuzanna Kurowska; Neural plasticitet och reparation; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LUHMES cells; substantia nigra pars compacta; microarray; heparan sulphate 3-O-sulfotransferase; neurocan; midbrain dopaminergic neurons; grafting; embryonic stem cells; proteoglycans; glycosaminoglycans; Nogo-A; cell replacement therapy; Parkinson’s disease;

    Abstract : Parkinson’s disease (PD) is currently the second most common neurodegenerative disorder (after Alzheimer’s disease). PD is diagnosed on its motor symptoms, which include akinesia, bradykinesia, rigidity, postural imbalance and resting tremor. It is well established that the motor symptoms develop due to lack of dopamine in the striatum. READ MORE
