  2. 1. Small RNAs, Big Consequences : Post-transcriptional Regulation and Adaptive Immunity in Bacteria

    Author : Mirthe Hoekzema; Gerhart E. H. Wagner; Magnus Lundgren; Kai Papenfort; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; small RNA; sRNA; non-coding RNA; Hfq; gene regulation; post-transcriptional regulation; biofilm; OmrA; OmrB; toxin-antitoxin; TisB; IstR-1; Persisters; CRISPR-Cas; CRISPR-Cas adaptation reporter; Escherichia coli; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : It is nowadays widely accepted that non-coding RNAs play important roles in post-transcriptional regulation of genes in all kingdoms of life. In bacteria, the largest group of RNA regulators are the small RNAs (sRNAs). READ MORE

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

    Author : Cecilia Unoson; E. Gerhart. H Wagner; Renée Schroeder; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small RNA; non-coding RNA; antisense; translational control; ribosome standby; toxin-antitoxin; IstR; TisB; tisAB; MicF; Lrp; Microbiology; Mikrobiologi; Cell and molecular biology; 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.

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

    Author : Klas Ifeanyi Udekwu; Gerhart Wagner; Tony Romeo; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small RNA; antisense; outer membrane; Hfq-dependence; RNase III; LuxS; Quorum sensing; Microbiology; 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

  6. 4. Exosomal Shuttle RNA

    Author : Karin Ekström; Göteborgs universitet; []
    Keywords : 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

  7. 5. Lead(II) as a Tool for Probing RNA Structure in vivo

    Author : Magnus Lindell; Gerhart Wagner; Roland Hartmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; lead II cleavage; RNA structure; in vivo probing; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Abstract : Chemical modification and limited enzymatic hydrolysis are powerful methods to obtain detailed information on the structure and dynamics of RNAs in solution. In the work presented here I have taken advantage of the properties of the divalent metal ion lead(II) to establish it as a new probe for investigating the structure of RNA in vivo. READ MORE
