  1. 1. Studies on mRNA turnover in bacteria

    Författare :Martin Persson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; aprE; GlpP; glpD; mRNA secondary structure; Bacillus subtilis; mRNA stability; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Genetic information, which is stored in DNA, is transferred to messenger RNA (mRNA) in a process called transcription. mRNAs are then translated by ribosomes into proteins which, with some important exceptions, catalyze chemical reactions in cells. Since cells must be able to adapt to changes in the environment, mRNAs must be unstable. LÄS MER

  3. 2. Preproenkephalin Gene and mRNA : Studies of Structure, Function, Cocaine Responses in an Animal Model, and Genetic Association with Human Opiate Addiction

    Författare :Karl Steven LaForge; Fred Nyberg; Peter S. Eriksson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological research on drug dependence; Neuropeptides; Endogenous opioid system; Drug addiction; Heroin; Cocaine; Gene expression; Genetic association; Biologisk beroendeforskning; Biological research on drug dependence; Biologisk beroendeforskning;

    Sammanfattning : The endogenous opioid enkephalin neuropeptides are mediators of pain perception and have been implicated in human addictions. The preproenkephalin gene and its mRNA have also provided many examples of tissue- and species-specific variations in mRNA structure produced through a variety of transcriptional and post-transcriptional mechanisms.

  4. 3. Allosteric Regulation of mRNA Metabolism : -Mechanisms of Cap-Dependent Regulation of Poly(A)-specific Ribonuclease (PARN)

    Författare :Per Nilsson; Anders Virtanen; Megerditch Kiledjian; Uppsala universitet; []
    Nyckelord :Cell and molecular biology; mRNA degradation; deadenylation; cap; poly A ; PARN; allosteric regulation; Cell- och molekylärbiologi;

    Sammanfattning : Degradation of mRNA is a highly regulated step important for proper gene expression. Degradation of eukaryotic mRNA is initiated by shortening of the 3’ end located poly(A) tail. Poly(A)-specific ribonuclease (PARN) is an oligomeric enzyme that degrades the poly(A) tail with high processivity. LÄS MER

  5. 4. The Bacillus subtilis GlpP protein, antitermination and mRNA stability

    Författare :Elisabeth Glatz; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; leader sequence; glpD; GlpP; catabolite repression; mRNA stability; Bacillus subtilis; antiterminator protein; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Bacillus subtilis can grow on glycerol or glycerol-3-phosphate (G3P) as the sole carbon and energy source. The glpD gene encodes G3P dehydrogenase which is required for the catabolism of glycerol and G3P. LÄS MER

  7. 5. Expression profiling using manifold supports

    Författare :Anette Hagberg; Joakim Lundeberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; mRNA; expression; minimal residual disease MRD ; chronic myeloid leukemia CML ; recombinant human erythropoietin r-HuEpo ; anemia; insulin dependent diabetes mellitus IDDM ; transplantation; Genetik; Clinical genetics; Klinisk genetik; Medical Genetics; medicinsk genetik;

    Sammanfattning : Analyses of mRNA provides a condensed view of gene structure and quantitative analysis can reveal the induction of physiological or pathological gene expression programs. This thesis describes a new method for mRNA isolation, followed by sensitive real time detection via polymerase chain reaction (PCR), in order to quantitate transcripts of interest. LÄS MER
