  1. 6. Genomic and Peptidomic Characterization of the Developing Avian Brain

    Författare :Birger Scholz; Lennart Dencker; Eric Vilain; Uppsala universitet; []
    Nyckelord :Toxicology; Sex differentation; Sex determination; Sex chromosomes; Dosage Compensation; Genetic; Chickens; Coturnix; Gene Expression Profiling; Neuropeptides; Diencephalon; Toxikologi;

    Sammanfattning : Chicken and Japanese quail are commonly used models in developmental and sex specific neuroendocrine research. There is relatively little known about the mechanisms behind their sex specific brain development, especially regarding the impact of the sex chromosomes (male: ZZ, female ZW) in relation to gonadal hormones.

  3. 7. Genetic Characterization of Chicken Models for Autoimmune Disease

    Författare :Anna-Stina Sahlqvist; Olov Ekwall; Olle Kämpe; Leif Andersson; Susanne Kerje; Holger Luthman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Autoimmune disease; Hashimoto’s thyroiditis; systemic sclerosis; comparative genomics; linkage analysis; OS chickens; spontaneous autoimmune thyroiditis; UCD-200 chickens.; Molekylär medicin; Molecular Medicine;

    Sammanfattning : Autoimmune diseases are endemic, but the disease mechanisms are poorly understood. A way to better understand these are to find disease-regulating genes. However, this is difficult as the diseases are complex, with several genes as well as environmental factors influencing the development of disease. LÄS MER

  4. 8. Domestication and early experiences in chickens : Behavior, stress and gene expression

    Författare :Pia Katrine Løtvedt; Per Jensen; Jordi Altimiras; Emma Brunberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A number of animal species have undergone domestication, the process of becoming adapted to living in captivity and in proximity to humans. Common for these species is that they have all developed certain traits, including changes to coat color, body size and level of fearfulness. This has been termed the domestic phenotype. LÄS MER

  5. 9. Domestication Effects on the Stress Response in Chickens : Genetics, Physiology, and Behaviour

    Författare :Amir Fallahshahroudi; Per Jensen; Frank Albert; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Animal domestication; stress response; gene expression; QTL; eQTL;

    Sammanfattning : Animal domestication, the process where animals become adapted to living in proximity to humans, is associated with the alteration of multiple traits, including decreased fearfulness and stress response. With an estimated population of 50 billion, the domesticated chicken is the most populous avian species in the world. LÄS MER

  7. 10. Correlated selection responses in animal domestication : the behavioural effects of a growth QTL in chickens

    Författare :Anders Wirén; Per Jensen; Elena Jazin; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Studying animal domestication offers an opportunity to understand the mechanisms of evolution. Domestication is associated with a change in selection pressures; selection for production traits is introduced, and animals are faced with larger and denser social groups. LÄS MER
