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

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

    Sammanfattning : 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. LÄS MER

  2. 7. Regulation of RNA Editing : The impact of inosine on the neuronal transcriptome

    Författare :Mikaela Behm; Marie Öhman; André Gerber; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; RNA editing; ADAR; miRNA; Neuron; Brain development; Synapse; Molecular Biology; molekylärbiologi;

    Sammanfattning : The transcriptome of the mammalian brain is extensively modified by adenosine to inosine (A-to-I) nucleotide conversion by two adenosine deaminases (ADAR1 and ADAR2). As adenosine and inosine have different base pairing properties, A-to-I RNA editing shapes the functional output of both coding and non-coding RNAs (ncRNAs) in the brain. LÄS MER

  3. 8. Regulatory roles of two small RNAs in the human pathogen Listeria monocytogenes and the evaluation of an alternative infection model

    Författare :Jonas Gripenland; Jörgen Johansson; Tom Geissmann; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small RNA; sRNA; Riboswitch; Listeria monocytogenes; ncRNA; PrfA; molekylärbiologi; Molecular Biology;

    Sammanfattning : Listeriosis is a potentially lethal disease caused by the Gram-positive facultative intracellular pathogen Listeria monocytogenes (L.m.). L. LÄS MER

  4. 9. Lead(II) as a Tool for Probing RNA Structure in vivo

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

    Sammanfattning : 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. LÄS MER

  5. 10. Function and Evolution of Small Regulatory RNAs and their Associated Proteins : A Journey from Genome to Proteome

    Författare :Bart Edelbroek; Fredrik Söderbom; Jonathan R. Chubb; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microRNAs; non-coding RNAs; Evolution; Whole Genome Sequencing; Transcriptomics; Proteomics; small RNAseq; Amoebozoa; Multicellular development; Social amoebae; Comparative genomics; Genome annotation; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Organisms throughout the tree of life have evolved distinct ways to regulate gene expression. Some of these processes involve non-coding RNAs (ncRNAs), which are not translated but functional nonetheless. These ncRNAs are of utmost importance, with dysregulation of some causing severe developmental effects or even being lethal. LÄS MER
