  1. 16. A holistic view on transcriptional regulatory networks in S. cerevisiae: Implications and utilization

    Författare :David Bergenholm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transcription factors; S. cerevisiae; chemostat; transcriptomics; regulatory networks;

    Sammanfattning : Life; perhaps it is bold to start an abstract with this powerful word, but this is where I will start. My research is at the heart of life. LÄS MER

  2. 17. On the Evolution of the Avian Transcriptome

    Författare :Severin Uebbing; Hans Ellegren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; evolution; gene expression; regulation; RNA-seq; transcriptomics; proteomics; sex chromosome; dosage compensation; divergence; ASE; birds; Ficedula; flycatcher; chicken; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Change in gene expression is a powerful tool for evolution, because seemingly small expression changes can contribute important steps towards adaptation without necessarily affecting the whole organism. There is still much to learn about how gene expression evolves on genome- and population-wide levels, especially in non-model organisms. LÄS MER

  3. 18. Comparative Genomics in Diplomonads : Lifestyle Variations Revealed at Genetic Level

    Författare :Feifei Xu; Jan O. Andersson; Staffan G. Svärd; Matt Berriman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; comparative genomics; Giardia intestinalis; Spironucleus salmonicida; Trepomonas; diplomonad; intestinal parasite; free-living; sexual recombination; hydrogenosome; horizontal gene transfer; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : As sequencing technologies advance genome studies are becoming a basic tool for studying an organism, and with more genomes available comparative genomics is maturing into a powerful tool for biological research. This thesis demonstrates the strength of a comparative genomics approach on a group of understudied eukaryotes, the diplomonads. LÄS MER

  4. 19. Development of Computational Methods for Cancer Research: Strategies for closing the feedback loop in omics workflows

    Författare :Ufuk Kirik; Institutionen för immunteknologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cancer; proteome profiling; bioinformatics; pathway analysis; mass spectrometry; Quantitative proteomics;

    Sammanfattning : As the ultimate workhorses of the living things, proteins undergo significant regulatory activity throughout the lifetime of a cell or an organism. Many complex diseases effect the protein composition, expression or modification in the cells or tissues they arise in. LÄS MER

  5. 20. Identification and characterisation of chitin and cellulose synthases in oomycetes : New tools for biochemical studies and structure determination

    Författare :Stefan Klinter; Vincent Bulone; Lauren S. McKee; Mirjam Czjzek; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biochemical characterisation; cellulose synthase; chitin synthase; in vitro activity assay; microtubule-interacting and trafficking domain; nanoparticle; oomycetes; phylogenetic analysis; yeast engineering; biokemisk karakterisering; cellulosasyntas; kitinsyntas; in vitro aktivitetsanalys; mikrotubulus-interagerande och -trafikerande domän; nanopartikel; oomyceter; fylogenetisk analys; jäst proteinteknik; Bioteknologi; Biotechnology;

    Sammanfattning : Despite resembling ‘true’ fungi in terms of morphological features, oo­mycetes form a distinct eukaryotic lineage of filamentous microorganisms that belongs to the stramenopiles, a group of protists also comprising the closely-related brown algae and diatoms. Many oomycetes are devastating pathogens of plants and animals, globally causing significant economic los­ses in the agriculture and aquaculture industries, and posing considerable environmental damage to natural ecosystems.
