  1. 21. Tropomyosin in Normal and Malignant Cells and the Action of Picropodophyllin on the Microfilament and Microtubule Systems

    Författare :Li-Sophie Zhao Rathje; Uno Lindberg; Roger Karlsson; J. Victor Small; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tropomyosin; Actin; Picropodophyllin; Tubulin; Cell motility; Cancer; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

    Sammanfattning : Cell motility is a fundamental process, enabling cells to migrate, for instance during embryogenesis, tissue repair and defense. Force is generated by two protein systems, which also participate in cell proliferation, control macromolecular and organelle distribution and determine the fine structure of the cell interior.

  3. 22. Identification and Characterization of the Moraxella catarrhalis IgD-binding Protein MID

    Författare :Andrea Möllenkvist; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; receptor; structure; phase variation; MID; IgD; Moraxella catarrhalis; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Moraxella catarrhalis is now an established human pathogen that frequently colonizes the upper respiratory tract causing most importantly otitis media in children. It has also been associated with sinusitis, laryngitis and lower respiratory tract infections in adults with predisposing conditions such as chronic obstructive pulmonary disease (COPD). LÄS MER

  4. 23. The Soluble Form of the Axl Receptor Tyrosine Kinase

    Författare :Carl Ekman; Malmö Klinisk kemi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The present investigation focus on the receptor Axl, which is a member of the receptor tyrosine kinase family. Axl is activated by the ligand Gas6 inducing cell growth and proliferation, but also regulate inflammation and vascular homeostasis. LÄS MER

  5. 24. Proteome studies, with emphasis on the kidney glomerulus

    Författare :Sam Tryggvason; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Proteomics aims to link genes to protein expression and function. Proteomics is a very versatile and technology-dependent discipline and the development of mass spectrometry-based proteomics has advanced the understanding of the complex and dynamic nature of proteomes. LÄS MER

  7. 25. The xanthophyll cycle, its enzymes, pigments and regulation

    Författare :Marie Eskling Carlsson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zeaxanthin; xanthophyll cycle; violaxanthin de-epoxidase; thylakoid; spinach; regulation; purification; pigments; photoprotection; pH dependence; ascorbate; light stress; Plant biochemistry; Växtbiokemi;

    Sammanfattning : The xanthophyll cycle involves the light-dependent and reversible conversion of violaxanthin to zeaxanthin. Zeaxanthin has been implicated in the protection of the photosynthetic machinery from over-excitation. The enzyme violaxanthin de-epoxidase catalyses the conversion of violaxanthin to zeaxanthin.
