    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Human Aquaporins; water channels; Protein-protein interaction; Regulation; AQP2; AQP0; LIP5; CaM;

    Sammanfattning : Water is an essential compoment of every living orgamism and forms a major part of the human body. Regulated water transport is crucial for proper cell functioning and body homeostasis. LÄS MER

  3. 22. Applications of Chromophores and Multiphoton Techniques to Study Structure and Interactions of Bio-macromolecules in Assembled State

    Författare :Piotr Hanczyc; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Z-scan; One-photon spectroscopy; oxazole yellow dyes; two-photon absorption.; non-linear spectroscopy; PVA DNA dyes films; linear dichroism; ruthenium complexes;

    Sammanfattning : The research presented in this thesis is concerned with the linear and nonlinear optical properties of biopolymers and the chromophores that bind to them. This thesis combines analyses of the interactions of biomolecules with technological improvements of already existing systems for bionanotechnology-related research. LÄS MER

  4. 23. Deciphering mechanisms of transcriptional activation and repression in B lymphocytes

    Författare :Stephen Malin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : During the course of evolution, our immune system has developed, to defend us against infections, a diverse number of specialized cell types. Immunoglobulin producing B lymphocytes are produced by the differentiation of hematopoietic stem cells (HSC) into gradually more lineage-restricted progenitors. LÄS MER

  5. 24. Molecular aspects of glutathione synthetase deficiency

    Författare :Runa Vidar Njålsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Glutathione synthetase; kinetics; cooperativity; substrate affinity; splice mutations; phenotype; genotype;

    Sammanfattning : The tripeptide glutathione (GSH) is involved in several crucial pathways in the cell, for instance regulation of enzyme activity, DNA synthesis, and free radical scavenging. Synthesis of GSH takes place via two steps in the gamma-glutamyl cycle. LÄS MER
