  1. 11. Biology of a small RNA virus that infects Drosophila melanogaster

    Författare :Sajna Anand Sadanandan; Dan Hultmark; Francis Jiggins; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nora virus; Drosophila melanogaster; virus biology; host-pathogen interaction; molekylärbiologi; Molecular Biology;

    Sammanfattning : Drosophila melanogaster has been extensively used as a model organism to study diverse facets of biology, including host-pathogen interactions and the basic biology of its pathogens. I have used the fruit fly as a model to study elementary aspects of Nora virus biology, such as the role of the different proteins encoded by the virus genome. LÄS MER

  3. 12. Diversification of TGF-β Signaling in Homeostasis and Disease

    Författare :Michael Vanlandewijck; Aristidis Moustakas; Carl-Henrik Heldin; Steven Dooley; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-β; signaling; SIK; EMT; polarity; Notch; ALK5; p21; growth arrest; Smurf; Smad7; receptor; SNF1LK; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Sammanfattning : With the dawn of metazoans, the ability of cells to communicate with each other became of paramount importance in maintaining tissue homeostasis. The transforming growth factor β (TGF-β) signaling pathway, which plays important roles during embryogenesis and in the adult organism, signals via a heterodimeric receptor complex consisting of two type II and two type I receptors.

  4. 13. 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

  5. 14. 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

  7. 15. Investigating Amyloid β toxicity in Drosophila melanogaster

    Författare :Maria Jonson; Per Hammarström; Stefan Thor; Christopher M Dobson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : In this thesis Drosophila melanogaster (the fruit fly) has been used as a model organism to study the aggregation and toxic properties of the human amyloid β (Aβ) peptide involved in the onset of Alzheimer's disease (AD). AD is one of many misfolding diseases where the important event of a protein to adopt its’ specific three-dimensional structure has failed, leading to aggregation and formation of characteristic amyloid fibrils.
