  2. 16. 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.

  4. 17. Biomolecular Aspects of Flexor Tendon Healing

    Author : Maria Berglund; Monica Wiig; Olof Nilsson; Jan Fridén; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Flexor tendon healing; Growth factor; Metalloproteinase; Collagen; Proteoglycan; Myofibroblast; Hyaluronan synthase; Mast cell; Hand surgery; Handkirurgi; Orthopaedics; Ortopedi;

    Abstract : Flexor tendon injuries in zone II of the hand (i.e. between the distal volar crease and the distal interphalangeal joint) can be costly for both the afflicted individual and society because of the high cost of a long rehabilitation period, complicated by tendon ruptures or scarring with adhesion formation, causing impaired range of motion.

  5. 18. Functional and molecular aspects of the glomerular barrier

    Author : Anna Björnson Granqvist; Göteborgs universitet; []
    Keywords : glomerular endothelium; glycocalyx; podocyte; proteoglycan; glycosaminoglycans; nephrotic syndrome;

    Abstract : The kidneys are crucial for maintaining a normal salt-water balance in the body, which is a prerequisite for life. They do that by filtering 180 liters of plasma per day across the highly permselective glomerular barrier and reabsorbing 99 % of the filtrate. READ MORE

  6. 19. Cellular design of heparan sulfate : The NDST enzymes and their regulation

    Author : Pernilla Carlsson; Lena Kjellén; Tarja Kinnunen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heparan sulfate; heparin; proteoglycan; NDST; PAPS; Golgi; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : Heparan sulfate proteoglycans are proteins with long, unbranched heparan sulfate (HS) polysaccharide chains attached to them. They are found on cell surfaces and in basement membranes where they exert their action by interacting with a wide range of enzymes and signaling molecules and are thereby involved in a range of various processes both during embryonic development and in adult physiology.

  7. 20. Mechanistic studies on the role of extracellular vesicles in the tumor microenvironment

    Author : Helena Christianson; Tumörmikromiljö; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microvesicle; exosome; Key words Extracellular vesicle; glioblastoma; hypoxia; angiogenesis; acidosis; proteoglycan; endocytosis; carbonic anhydrase IX; biomarker.;

    Abstract : The transition from normal into malignant cells with acquired uncontrolled growth is a process where cancer cells viciously develop adaptive strategies to overcome microenvironmental and metabolic stress. Hypoxia, or deficient oxygen supply, is a common feature of the expanding tumor which alters cell metabolism and consecutively causes lowered intracellular pH. READ MORE
