  1. 1. Characterization of RNA exosome in Insect Cells Role in mRNA Surveillance

    Detta är en avhandling från Stockholm : Department of Molecular Biology and Functional Genomics, Stockholm University

    Författare :Viktoria Hessle; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cell nucleus; nuclear bodies; mRNA surveillance; cotranscriptional assembly; Rrp6; Rrp4; mRNP; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : The exosome, an evolutionarily conserved protein complex with exoribonucleolytic activity, is one of the key players in mRNA quality control. Little is known about the functions of the exosome in metazoans. We have studied the role of the exosome in nuclear mRNA surveillance using Chironomus tentans and Drosophila melanogaster as model systems. LÄS MER

  2. 2. Spatial control of mRNA stability in yeast

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Susanne Huch; Umeå universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mRNA stability; P bodies; mRNA turnover; gene regulation; decapping factors; molekylärbiologi; Molecular Biology;

    Sammanfattning : The degradation of mRNA is an important modulator of gene expression and the ultimate fate of messenger mRNA. Important steps in the degradation of mRNA include initial shortening of its poly(A) tail followed by the subsequent removal of the m7G cap. These two processes are linked temporally as well as spatially. LÄS MER

  3. 3. Studies on mRNA turnover in bacteria

    Detta är en avhandling från Biology building

    Författare :Martin Persson; Lunds universitet.; Lund University.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; aprE; GlpP; glpD; mRNA secondary structure; Bacillus subtilis; mRNA stability; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Popular Abstract in Swedish Genetisk information lagras i DNA, som är en mycket stabil molekyl. I våra celler finns samma gener i alla celler. Det är därför av yttersta vikt att uttrycket av generna kan regleras olika i olika vävnader. LÄS MER

  4. 4. mRNA degradation factors as regulators of the gene expression in Saccharomyces cerevisiae

    Detta är en avhandling från Umeå : Umeå University

    Författare :Mridula Muppavarapu; Umeå universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mRNA decapping; mRNA degradation; Pat1; Edc3; Lsm4; Lsm1-7; P bodies; Dcp2; Transcription; Ribosome biogenesis; Exosome.; molekylärbiologi; Molecular Biology;

    Sammanfattning : Messenger RNA degradation is crucial for the regulation of eukaryotic gene expression. It not only modulates the basal mRNA levels but also functions as a quality control system, thereby controlling the availability of mRNA for protein synthesis. LÄS MER

  5. 5. High-resolution Studies of mRNA Expression in Brain A Search for Genes Differently Expressed in Schizophrenia

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anja Castensson; Uppsala universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; mRNA; gene expression; real-time RT-PCR; schizophrenia; 5-HT serotonin receptor 2C; brain; psychiatric genetics; Genetik; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Klinisk genetik;

    Sammanfattning : Gene expression differences between patients and controls can be used to find susceptibility genes and drug targets for a disease. High-resolution strategies are required because the differences between the investigated groups may be small and numerous factors may affect the mRNA quantity. LÄS MER
