  2. 1. Computational Problems in Modeling Evolution and Inferring Gene Families

    Author : Mehmood Alam Khan; Lars Arvestad; Jens Lagergren; Christophe Dessimoz; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evolution; Phylogenetics; Lateral Gene Transfer; Gene Families; Clustering; Datalogi; Computer Science;

    Abstract : Over the last few decades, phylogenetics has emerged as a very promising field, facilitating a comparative framework to explain the genetic relationships among all the living organisms on earth. These genetic relationships are typically represented by a bifurcating phylogenetic tree — the tree of life. READ MORE

  4. 2. Probabilistic Modelling of Domain and Gene Evolution

    Author : Sayyed Auwn Muhammad; Jens Lagergren; Bastien Boussau; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phylogenetics; Phylogenomics; Evolution; Domain Evolution; Gene tree; Domain tree; Bayesian Inference; Markov Chain Monte Carlo; Homology Inference; Gene families; C2H2 Zinc-Finger; Reelin Protein; Computer Science; Datalogi;

    Abstract : Phylogenetic inference relies heavily on statistical models that have been extended and refined over the past years into complex hierarchical models to capture the intricacies of evolutionary processes. The wealth of information in the form of fully sequenced genomes has led to the development of methods that are used to reconstruct the gene and species evolutionary histories in greater and more accurate detail.

  5. 3. Evolution of Vertebrate Endocrine and Neuronal Gene Families : Focus on Pituitary and Retina

    Author : Daniel Ocampo Daza; Dan Larhammar; Marc Robinson-Rechavi; Uppsala universitet; []
    Keywords : phylogenetics; evolution; molecular evolution; gene family evolution; genome duplication; gene duplication; oxytocin receptor; vasopressin receptor; visual opsin; transducin; growth hormone; prolactin; somatolactin; growth hormone receptor; prolactin receptor; somatostatin receptor; SSTR; IGFBP; evolution; molekylär evolution; fylogeni;

    Abstract : The duplication of genes followed by selection is perhaps the most prominent way in which molecular biological systems gain multiplicity, diversity and functional complexity in evolution. Whole genome duplications (WGDs) therefore have the potential of generating an extraordinary amount of evolutionary innovation. READ MORE

  6. 4. Hypospadias : gene mapping and candidate gene studied

    Author : Thi Thai Hanh Trinh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Hypospadias is a common congenital malformation in boys, characterized by incomplete fusion of the urethral folds, abnormal opening of urethra and different degrees of curvature of the penis. In Sweden, the incidence of hypospadias is 1.14 per 300 male live-births according to the annual Swedish Malformation Registry. READ MORE

  7. 5. Genetic studies on Systemic Lupus Erythematosus : A fine mapping and candidate gene approach

    Author : Veronica Magnusson; Jerry Lanchbury; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; Systemic Lupus Erythematosus; complex disease; linkage analysis; candidate gene; association studies; Genetik; Genetics; Genetik; medicinsk genetik; Medical Genetics;

    Abstract : Linkage in the 2q37 region was evaluated using microsatellite markers in multi-case families from Sweden, Iceland and Norway. Both the two-point and the multipoint linkage analysis show highly significant LOD scores (Z=4.51 and 6.03, respectively). READ MORE
