  1. 36. Genetic and Molecular analysis of the Spinocerebellar ataxia type 7 (SCA7) disease gene

    Författare :Jenni Jonasson; Monica Holmberg; Christine Van Broeckhoven; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Spinocerebellar ataxia; human genetics; linkage analysis; anticipation; CAG repeat expansion; founder effect; protein expression; ATXN7; Medical genetics; Medicinsk genetik;

    Sammanfattning : Spinocerebellar ataxia type 7 (SCA7) is a hereditary neurodegenerative disorder affecting the cerebellum, pons and retina. SCA7 patients present with gait ataxia and visual impairment as the main symptoms. LÄS MER

  3. 37. A molecular biological study of Alzheimer's disease : investigation of amyloid precursor protein, amyloid precursor-like protein 2 and presenilin-1

    Författare :Janet A Johnston; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The devastating symptoms of Alzheimer's disease result from a progressive regional neurodegenerative process, the cause of which is unknown. Current research suggests that several different mechanisms may be involved, perhaps acting at different points in a common pathological pathway. LÄS MER

  4. 38. Atypical Solute Carriers : Identification, evolutionary conservation, structure and histology of novel membrane-bound transporters

    Författare :Emelie Perland; Robert Fredriksson; Helgi Schiöth; Åsa Mackenzie; Sonchita Bagchi; Carsten Uhd Nielsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Major facilitator superfamily; solute carrier; transporter; protein expression; mRNA expression; phylogenetic clustering; orthologues; co-expression; subcellular location; nutrition.; Neuroscience; Neurovetenskap;

    Sammanfattning : Solute carriers (SLCs) constitute the largest family of membrane-bound transporter proteins in humans, and they convey transport of nutrients, ions, drugs and waste over cellular membranes via facilitative diffusion, co-transport or exchange. Several SLCs are associated with diseases and their location in membranes and specific substrate transport makes them excellent as drug targets. LÄS MER

  5. 39. Towards Classification and Functional Description of Enzymes: A case study of feruloyl esterases

    Författare :Gupta Udatha; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; descriptors; enzyme immobilization; catalytic triad; pharmacophore; enzyme promiscuity; functional classification; molecular docking; feruloyl esterases; protein evolution; structure-function relationship;

    Sammanfattning : The prediction of enzyme functionality from sequence or structure data remains a challenging task that can be best addressed by studying the structure-function relationships determined from previously available information. This thesis work was focused on developing a reliable classification and functional description for the feruloyl esterase (FAE) enzyme family, whose members’ possess both structural and catalytic promiscuity.

  7. 40. G Protein-Coupled Receptors; Discovery of New Human Members and Analyses of the Entire Repertoires in Human, Mouse and Rat

    Författare :David E. Gloriam; Helgi Schiöth; Robert Fredriksson; Darren Flower; Uppsala universitet; []
    Nyckelord :Bioinformatics; G protein-coupled receptor; GPCR; Bioinformatics; Evolution; Orphan; Rhodopsin; Adhesion; Phylogeny; Bioinformatik;

    Sammanfattning : G protein-coupled receptors (GPCRs) are signal mediators that have a prominent role in the regulation of physiological processes and they make up the targets for 30-45% of all drugs. Papers I and II describe the discovery of new human GPCRs belonging to the Rhodopsin family, a family which contains many common drug targets. LÄS MER
