    Sammanfattning : 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.

    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Making Sense of Antisense

    Författare :Johan Reimegård; Gerhart Wagner; Hanah Margalit; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sRNA; miRNA; RNA; target prediction; SOLiD siRNA; E.coli; D.discoideum; Biology; Biologi; Bioinformatics; Bioinformatik; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : RNA is a highly versatile molecule with functions that span from being a messenger in the transfer from DNA to protein, a catalytic molecule important for key processes in the cell to a regulator of gene expression. The post-genomic era and the use of new techniques to sequence RNAs have dramatically increased the number of regulatory RNAs during the last decade. LÄS MER

  5. 4. CopA and CopT: The Perfect RNA Couple

    Författare :Jacoba G. Slagter-Jäger; Gerhart Wagner; Wolfgang Nellen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; antisense RNA; plasmid; U-turn; four-way junction; RNA-RNA interaction; Hfq; Mikrobiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Sammanfattning : Antisense RNAs regulate gene expression in many bacterial systems. The best characterized examples are from prokaryotic accessory elements such as phages, plasmids and transposons. Many of these antisense RNAs have been identified as plasmid copy number regulators where they regulate the replication frequency of the plasmid by negative feedback. LÄS MER
