  1. 1. Ligand binding and enzyme catalysis studied by molecular dynamics simulations

    Författare :Tomas Hansson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; molecular dynamics simulation; free energy; linear response; drug design; empirical valence bond; HIV protease; protein tyrosine phosphatase; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Molecular dynamics simulations and free energy calculations can be applied to biomolecular systems to predict ligand binding affinities. Combined with hybrid quantum-classical potential energy surfaces, such computations can also be used to probe enzymatic catalysis mechanisms. LÄS MER

  2. 2. Stress response and virulence in Vibrio anguillarum

    Författare :Barbara Weber; Debra L. Milton; James D. Oliver; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vibrio anguillarum; quorum sensing; Type VI secretion; stress response; virulence; skin colonization; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Bacteria use quorum sensing, a cell to cell signaling mechanism mediated by small molecules that are produced by specific signal molecule synthases, to regulate gene expression in response to population density. In Vibrio anguillarum, the quorum-sensing phosphorelay channels information from three hybrid sensor kinases VanN, VanQ, CqsS that sense signal molecules produced by the synthases VanM, VanS and CqsA, onto the phosphotransferase VanU, to regulate activity of the response regulator VanO.

    Sammanfattning : Adenovirus serotype 5 (Ad5) is widely used as an oncolytic agent for cancer therapy. However, its infectivity is highly dependent on the expression level of coxsackievirus-adenovirus receptor (CAR) on the surface of tumor cells. LÄS MER

  4. 4. Molecular Signatures of Cancer

    Författare :Esther Edlundh-Rose; Joakim Lundeberg; Peter Södervist; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; : BRAF; NRAS; MGMT; methylation; pyrosequencing; microarray technology; gene expression analysis; Molecular biology; Molekylärbiologi;

    Sammanfattning : Cancer is an important public health concern in the western world, responsible for around 25% of all deaths. Although improvements have been made in the diagnosis of cancer, treatment of disseminated disease is inefficient, highlighting the need for new and improved methods of diagnosis and therapy.

  5. 5. Molecular Regulation of Angiogenesis

    Författare :Sofie Mellberg; Lena Claesson-Welsh; Frank Böhmer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endothelial morphogenesis; VEGFR-2; protein tyrosine phosphatase; VE-PTP; PTPRB; endocan; ESM-1; angiogenesis; Molecular medicine; Molekylär medicin;

    Sammanfattning : Angiogenesis, de novo formation of blood vessels from the pre-existing vasculature, is crucial in embryo development, and in processes in the adult such as wound healing and ovulation. Angiogenesis is also involved in pathological conditions such as cancer and chronic inflammatory diseases, which are propagated by dysregulated, excess angiogenesis. LÄS MER
