  1. 6. Macromolecular Matchmaking : Mechanisms and Biology of Bacterial Small RNAs

    Författare :Erik Holmqvist; E. Gerhart H. Wagner; Udo Bläsi; Uppsala universitet; []
    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

  3. 7. Targeting RNA by the Antisense Approach and a Close Look at RNA Cleavage Reaction

    Författare :Jharna Barman; Lars Baltzer; Roger Strömberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; mRNA targeting; antisense oligonucleotides; target affinity; RNase H; Michaelis-Menten kinetics; exo-nuclease stability; NMR; pH titration; alkaline hydrolysis; Organisk kemi;

    Sammanfattning : This thesis summarizes the results of studies on two aspects of nucleic acids. Chemically modified antisense oligonucleotides (AONs) have been evaluated with regards to their suitability for mRNA targeting in an antisense approach (Paper I – III). LÄS MER

  4. 8. On Transcriptome Sequencing

    Författare :Daniel Klevebring; Joakim Lundeberg; Ulf Gyllensten; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transcriptome; RNA-seq; DNA sequencing; gene expression profiling; non-coding RNA; small RNA; Functional genomics; Funktionsgenomik; Bioinformatics; Bioinformatik; Genetics; Genetik; Molecular biology; Molekylärbiologi; Cell biology; Cellbiologi;

    Sammanfattning : This thesis is about the use of massive DNA sequencing to investigate the transcriptome. During recent decades, several studies have made it clear that the transcriptome comprises a more complex set of biochemical machinery than was previously believed. LÄS MER

  5. 9. Analysis of regulatory RNA in accessory elements of Escherichia coli : antisense RNA control in plasmid R1 & self-splicing introns in bacteriophage T4

  7. 10. Molecular Insights into Kcnq1ot1 Noncoding Antisense RNA Mediated Long Range Transcriptional Gene Silencing

    Författare :Radha Raman Pandey; Chandrasekhar Kanduri; Karl Ekwall; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epigenetics; gene silencing; noncoding RNA; genomic imprinting; Kcnq1ot1; Medical genetics; Medicinsk genetik;

    Sammanfattning : Non-coding antisense RNAs have been implicated in the epigenetic silencing of individual gene as well as chromosomal domains. While silencing of the overlapping gene by antisense RNAs has been well investigated, their functional role in silencing of chromosomal domains remains enigmatic. LÄS MER
