  2. 1. Cytochrome c Oxidase dysfunction in cancer : Exploring the molecular mechanisms

    Author : Ida Namslauer; Peter Brzezinski; Susanne Arnold; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

    Abstract : Mutations in genes encoding the mitochondrial enzyme Cytochrome c Oxidase (CytcO) have lately been found in connection to various types of cancer. Some mutations result in substitutions of highly conserved amino-acid residues. READ MORE

  4. 2. Virulence mechanisms of pathogenic Yersinia : aspects of type III secretion and twin arginine translocation

    Author : Moa Lavander; Åke Forsberg; George Salmond; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Yersinia pestis; Yersinia pseudotuberculosis; bacterial pathogenesis; type III secretion; twin arginine translocation; virulence mechanisms; YscU; YscP; YscF; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The pathogenic bacteria Yersinia pestis and Y. pseudotuberculosis are related to the degree where the former is considered a subspecies of the latter, and still they cause disease of little resemblance in humans. Y. pestis is the causative agent of lethal bubonic and pneumonic plague, while Y. READ MORE

  5. 3. Ligand binding and enzyme catalysis studied by molecular dynamics simulations

    Author : Tomas Hansson; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Molecular Signatures of Cancer

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

    Abstract : 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.

  7. 5. Molecular Regulation of Angiogenesis

    Author : Sofie Mellberg; Lena Claesson-Welsh; Frank Böhmer; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
