  1. 6. REGULATED UPTAKE OF BIOPOLYMERS Role of cell surface proteoglycans Implications for drug and gene delivery

    Författare :Staffan Sandgren; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Cytology; oncology; proliferation; differentiation; Medicine human and vertebrates ; growth factor; cancer; drug delivery; gene therapy; LL-37; HIV-Tat; cell penetrating peptides; polyamines; heparan sulfate; onkologi; Cytologi; cancerology; internalization; proteoglycans;

    Sammanfattning : Cells continuously export, import, and recycle molecules over the plasma membrane. Internalization, i.e. cellular import of extracellular material, is a fundamental process, which provides cells with nutrients and enables the immune cells of higher organisms to remove debris, sample their surroundings for antigens and to fight microbes.

  3. 7. Intracellular Uptake and Membrane Binding of Cell-penetrating Peptides: The Influence of Arginines, Tryptophans and Proteoglycans

    Författare :Hanna Rydberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptides; membrane-binding; cellular uptake; proteoglycans; tryptophan; arginine-rich peptide;

    Sammanfattning : One of the major limitations in the realization of functional gene therapy is efficient intracellular transport of the therapeutic macromolecules. Amongst several different techniques, cell-penetrating peptides (CPPs) have emerged as promising candidates for this purpose. LÄS MER

  4. 8. Adaptive mechanisms in the hypoxic tumor microenvironment. Functional role of proteoglycans and identification of potential treatment targets

    Författare :Julien Menard; Tumörmikromiljö; []
    Nyckelord :Hypoxia; Acidosis; Proteoglycans; Endocytosis; Glioblastoma; Lipid; Caveolin-1; Antibody-drug conjugate;

    Sammanfattning : Cancer cells reside in a complex microenvironment comprising stromal cells and immune cells embedded in an extracellular matrix (ECM). Early on in tumor progression, cells reach a critical volume beyond which blood supply is impaired, leading to a decrease in oxygen levels (hypoxia) and nutrient supply. LÄS MER

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

    Författare :Zuzanna Kurowska; Neural plasticitet och reparation; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 10. Heparan Sulfate Proteoglycans in Brain Tumor Development

    Författare :Argyris Spyrou; Karin Forsberg Nilsson; Fredrik Johansson Swartling; Jöns Hilborn; John Couchman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glioma; pediatric brain tumors; heparanase; NDST1; heparan sulfate proteoglycans; CD24; glycosaminoglycan mimetics; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Sammanfattning : Malignant brain tumors are aggressive neoplasms that remain challenging to treat in spite of their detailed molecular characterization. Both adults and children may suffer from brain tumors, which, if not lethal, can cause severe long-term and devastating side effects. LÄS MER
