  1. 26. Classification, Evolution, Pharmacology and Structure of G protein-coupled Receptors

    Författare :Malin C Lagerström; Helgi B. Schiöth; Robert Fredriksson; Anthony J. Harmar; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; Classification; Structure; Pharmacology; Evolution; G protein-coupled receptor; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Sammanfattning : G protein-coupled receptors (GPCR) are integral membrane proteins with seven α-helices that translate a remarkable diversity of signals into cellular responses. The superfamily of GPCRs is among the largest and most diverse protein families in vertebrates. LÄS MER

  3. 27. Characterization of chromosome abnormalities

    Författare :Anna Lindstrand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Inborn chromosome abnormalities are a frequent cause of mental retardation and birth defects. Apart from aberrations that are visible in the microscope, a number of submicroscopic alterations have recently been discovered, and all of these chromosome changes are in fact the result of DNA alterations at the molecular level.

  4. 28. Reconciling gene family evolution and species evolution

    Författare :Joel Sjöstrand; Jens Lagergren; Nicolas Lartillot; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational biology; Bioinformatics; Phylogenetics; Phylogenomics; Comparative genomics; Evolutionary biology; datalogi; Computer Science;

    Sammanfattning : Species evolution can often be adequately described with a phylogenetic tree. Interestingly, this is the case also for the evolution of homologous genes; a gene in an ancestral species may – through gene duplication, gene loss, lateral gene transfer (LGT), and speciation events – give rise to a gene family distributed across contemporaneous species.

  5. 29. Genomics and Evolution Studies of Dekkera bruxellensis, a Wine-Spoilage Yeast

    Författare :Elzbieta Rozpedowska; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Yeasts are unicellular fungi exhibiting a huge diversity of life styles and physiologies and their evolutionary span exceeds the one between mammals and unchordates. The recent advances in genome sequencing and comparative genomics accelerated genomic, evolutionary and physiological studies of yeasts, making them a very promising model to study eukaryotic cell, and also deepened our understanding of the molecular background of yeasts physiologies.

  7. 30. Patterns and Processes of Molecular Evolution in Rickettsia

    Författare :Haleh Amiri; Dan Andersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Species of the genus Rickettsia are obligate intracellular parasites of the a-proteobacterial subdivision. It has been suggested that obligate intracellular bacteria have evolved from free-living bacteria with much larger genome sizes. LÄS MER
