  1. 1. Thioredoxins and gene regulation in the Drosophila germline

    Författare :Malin J. Svensson; Jan Larsson; David Roberts; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila; thioredoxin; sex-specific; Pof; chromosome 4; gene regulation; kromosom 4; genreglering; Drosophila; thioredoxin; könsspecifik; Pof; Molecular biology; Molekylärbiologi;

    Sammanfattning : Spermatogenesen är i många organismer en av de mest dramatiska förvandlingar som en cell kan genomgå – en vanlig, rund, diploid cell omvandlas till en nålformad, haploid cell med ett tätt packat cellmaskineri. I bananfluga, Drosophila melanogaster, innebär denna process flera karaktäristiska stadier. LÄS MER

  3. 2. On gene regulatory networks and data fitting

    Författare :Karl Fogelmark; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :Circadian rhythms; gene regulation; transcription networks; correlated data; Circadian rhythms; gene regulation; transcription networks; correlated data; Fysicumarkivet A:2016:Fogelmark;

    Sammanfattning : Living organisms can be viewed as complex biological machines. In order to function, they must regulate their internal mechanism to do the right thing, at the right time, and in the right amount. Part of this regulation is encoded in gene regulatory networks. LÄS MER

  4. 3. Exploring the multiscale 3D architecture of human chromosome contact networks

    Författare :Dolores Bernenko; Ludvig Lizana; Martin Rosvall; Petter Holme; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; community detection; DNA 3D organization; Hi-C; network science; DNA-DNA contact data;

    Sammanfattning : Cells regulate genes to coordinate essential functions allowing cells to grow, divide, specialize, and respond to stresses. While regulatory proteins are the most common way to control these genes, the DNA’s 3D structure also plays a critical role as it affects how proteins access genes and how regulatory DNA elements interact over large genomic distances.

  5. 4. Studies on mRNA turnover in bacteria

    Författare :Martin Persson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; aprE; GlpP; glpD; mRNA secondary structure; Bacillus subtilis; mRNA stability; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Genetic information, which is stored in DNA, is transferred to messenger RNA (mRNA) in a process called transcription. mRNAs are then translated by ribosomes into proteins which, with some important exceptions, catalyze chemical reactions in cells. Since cells must be able to adapt to changes in the environment, mRNAs must be unstable. LÄS MER

  7. 5. Identification and Characterization of the Moraxella catarrhalis IgD-binding Protein MID

    Författare :Andrea Möllenkvist; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; receptor; structure; phase variation; MID; IgD; Moraxella catarrhalis; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Moraxella catarrhalis is now an established human pathogen that frequently colonizes the upper respiratory tract causing most importantly otitis media in children. It has also been associated with sinusitis, laryngitis and lower respiratory tract infections in adults with predisposing conditions such as chronic obstructive pulmonary disease (COPD). LÄS MER
