  1. 1. Exosomal Shuttle RNA

    Author : Karin Ekström; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; exosomes; exosomal; shuttle; RNA; esRNA; vesicles; mast cell; gene transfer; microRNA;

    Abstract : Exosomes are small membrane nanovesicles of endocytic origin that can be released by many different cells to the extracellular environment. Exosomes have been found in a number of body fluids such as blood plasma, breast milk, bronchoalveolar lavage fluid and urine, indicating relevance in vivo. READ MORE

  2. 2. Small RNA-mediated Regulation of Gene Expression in Escherichia coli

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Cecilia Unoson; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small RNA; non-coding RNA; antisense; translational control; ribosome standby; toxin-antitoxin; IstR; TisB; tisAB; MicF; Lrp; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : Non-coding RNAs are highly abundant regulators of gene expression in all kingdoms of life that often play important roles in vital cellular functions. In bacteria, small regulatory RNAs (sRNAs) usually act post-transcriptionally by regulating mRNAs through base pairing within ribosome binding sites (RBS), thereby inhibiting translation initiation.

  3. 3. Macromolecular Matchmaking Mechanisms and Biology of Bacterial Small RNAs

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Holmqvist; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Small RNA; sRNA; non-coding RNA; antisense; gene regulation; post-transcriptional regulation; translational control; outer membrane protein; OmpA; MicA; biofilm; flagella; curli; bistability; Lrp; MicF; CsgD; FlgM; OmrA; OmrB; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : Cells sense the properties of the surrounding environment and convert this information into changes in gene expression. Bacteria are, in contrast to many multi-cellular eukaryotes, remarkable in their ability to cope with rapid environmental changes and to endure harsh and extreme milieus. READ MORE

  4. 4. Structure of small RNA phages

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kaspars Tars; Uppsala universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; bacteriophage; MS2; virus assembly; structural evolution; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Small RNA phages belonging to the family Leviviridae are among the simplest known viruses. They have been used extensively as models for studies of various problems in molecular biology, including protein-RNA interactions, repression of translation, virus assembly and virus evolution.

  5. 5. Functional characterization of the small antisense RNA MicA in Escherichia coli

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Klas Ifeanyi Udekwu; Uppsala universitet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small RNA; antisense; outer membrane; Hfq-dependence; RNase III; LuxS; Quorum sensing; MEDICINE Microbiology; immunology; infectious diseases Microbiology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Mikrobiologi; mikrobiologi; Microbiology;

    Abstract : The Escherichia coli small RNA (sRNA) MicA was identified recently in a genomewide search for sRNAs. It is encoded between the genes gshA and luxS in E. coli and its close relatives. The function of sRNAs in bacteria is generally believed to be in maintenance of homeostasis via stress-induced modulation of gene expression. READ MORE
