  1. 1. Hybridization and Evolution in the Genus Pinus

    Författare :Baosheng Wang; Xiao-Ru Wang; Sally Aitken; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adaptation; biogeography; coalescent simulation; cytoplasmic genome; demographic history; genetic diversity; hybridization; migration; Pinus; population structure; selection; speciation; evolutionär genetik; evolutionary genetics;

    Sammanfattning : Gene flow and hybridization are pervasive in nature, and can lead to different evolutionary outcomes. They can either accelerate divergence and promote speciation or reverse differentiation. The process of divergence and speciation are strongly influenced by both neutral and selective forces.

  3. 2. The roles of demography and natural selection in shaping genome-wide variation of Norway spruce

    Författare :Xi Wang; Pär K. Ingvarsson; Carolina Bernhardsson; Xiao-Ru Wang; Nathaniel Street; Tanja Pyhäjärvi; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; whole-genome resequencing; variant calling; genetic linkage map; nucleotide diversity; natural selection;

    Sammanfattning : Understanding the relative contribution of genetic drift, natural selection, and mutation to genetic variation, and quantifying adaptive evolution and the effects of natural selection in species are enduring goals of evolutionary genetics. Norway spruce (Picea abies) is one of the most important conifer species that dominates from both an ecological and economical point of view in many boreal ecosystems. LÄS MER

  4. 3. New molecular markers in mantle cell lymphoma : studies of cannabinoid receptors, 5-lipoxygenase and SOX11

    Författare :Xiao Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mantle cell lymphoma (MCL) is a malignant B-cell lymphoma that accounts for 5-10% of all lymphomas and tends to occur in older adults with a higher incidence in males. The genetic hallmark of this neoplasm is the t(11;14) translocation which results in overexpression of nuclear cyclin D1. LÄS MER

  5. 4. Immune modulation of macrophages by the meningococcal surface protein NhhA

    Författare :Xiao Wang; Hong Sjölinder; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Functional immune modulation of macrophages play important role during bacterial infection. Neisseria meningitidis, a gram-negative diplococcal bacterium, is the leading cause of bacterial meningitis and fatal septic shock. However, it is also a commensal bacterium that colonizes the nasopharynx of healthy individuals asymptomatically. LÄS MER

  7. 5. Macrophage programming and host responses to bacterial infection

    Författare :Xiao Wang; Hong Sjölinder; Martin Rottenberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Macrophages; meningococci; mycobacteria; NhhA; CD46; cytokines; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Macrophages are dynamic, plastic, and heterogeneous immune cells that play an important role in host immune defense against bacterial infection. Various bacterial pathogens, such as Neisseria meningitidis and Mycobacterium tuberculosis, can modulate host immune responses by interfering with macrophage differentiation and polarization. LÄS MER
