    Författare :Ignas Bunikis; Sven Bergström; Steven Norris; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; Lume disease; relapsing fever; BesC; drug efflux; DipA; P66; porins; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Borrelia is a Gram-negative, corkscrew-shaped bacterium transmitted by infected ticks or lice. Borreliae are subdivided into pathogens of two diseases: Lyme disease, caused mainly by B. burgdorferi, B. afzelii and B. LÄS MER

  2. 12. Modelling Approaches to Molecular Systems Biology

    Författare :David Fange; Måns Ehrenberg; Johan Elf; Terence Hwa; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stochastic reaction-diffuion kinetics; antibiotic drugs; efflux pumps; amino acid biosynthesis; Min-system; rRNA operon; transcription; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Implementation and analysis of mathematical models can serve as a powerful tool in understanding how intracellular processes in bacteria affect the bacterial phenotype. In this thesis I have implemented and analysed models of a number of different parts of the bacterium E. coli in order to understand these types of connections. LÄS MER

  3. 13. Biased Evolution : Causes and Consequences

    Författare :Gerrit Brandis; Diarmaid Hughes; Erik Böttger; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; Codon usage bias; Post-transcriptional regulation; Recombination; Inversion; EF-Tu; Frameshift suppression; Antibiotic resistance; Rifampicin; Ciprofloxacin; Compensatory evolution; Drug efflux; RNA polymerase; DNA gyrase; Mikrobiologi; Microbiology;

    Sammanfattning : In evolution alternative genetic trajectories can potentially lead to similar phenotypic outcomes. However, certain trajectories are preferred over others. These preferences bias the genomes of living organisms and the underlying processes can be observed in ongoing evolution. LÄS MER

  4. 14. Heterogeneity of leukemic cells with regard to daunorubicin accumulation and efflux : potential role in drug resistance

    Författare :Eva Knaust; Linköpings universitet; []
    Nyckelord :Drug resi stance. acute myeloid leukemia; flow cytometry; gene expression; transport kinetics; apoptosis; MEDICINE; MEDICIN;

    Sammanfattning : Cellular resistance to chemotherapy is a major cause of treatment failure in acute myelocytic leukemia (AML) and other malignancies. Drug resistance is multifactorial; the most studied mechanism being multidrug resistance (MDR), mediated by the P-glycoprotein (PPG), a transmembrane transport protein with a pump function, encoded by the mdr 1 gene.

  5. 15. Structure, Function and Regulation of Fps1p. A Eukaryotic Solute Efflux Channel

    Författare :Kristina Hedfalk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NPA-motif; Fps1p; regulation; overexpression; osmoadaptation; glycerol facilitator; MIP;

    Sammanfattning : Integral membrane proteins belonging to the Major Intrinsic Protein (MIP) family can be found in all kingdoms of life. MIPs are transporters of water, small neutral solutes and possibly ions, and hence are important for osmoregulation at different levels. LÄS MER
