  1. 1. Regulation of immunoglobulin transcription

    Författare :David Liberg; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; N-substituted benzamides; NFkB; transcription; B cells; immunoglobulin; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : Each Ig V-region has its own upstream promoter and the promoter of a mature Ig gene is thereby selected during the V(D)J recombination process. Upon comparison, it is evident that only one transcription factor binding site, the octamer, is preserved within all promoters. LÄS MER

  3. 2. Statistical models of TF/DNA interaction

    Författare :Aymeric Fouquier d'Herouel; Erik Aurell; Otto Berg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gene expression; regulation; transcription factor; binding motif; matrix representations; gibbs sampling; binding affinity; non-specific binding; Biological physics; Biologisk fysik;

    Sammanfattning : Gene expression is regulated in response to metabolic necessities and environmental changes throughout the life of a cell. A major part of this regulation is governed at the level of transcription, deciding whether messengers to specific genes are produced or not. LÄS MER

  4. 3. A Bioinformatics Study of Human Transcriptional Regulation

    Författare :Adam Ameur; Jan Komorowski; Claes Wadelius; Philipp Bucher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; microarray; ChIP-chip; ChIP-seq; transcription factor; histone modification; motif search; Bioinformatics; Bioinformatik;

    Sammanfattning : Regulation of transcription is a central mechanism in all living cells that now can be investigated with high-throughput technologies. Data produced from such experiments give new insights to how transcription factors (TFs) coordinate the gene transcription and thereby regulate the amounts of proteins produced. LÄS MER

  5. 4. Herpes Simplex Virus 1 DNA replication and its role in recombination and transcription

    Författare :Ka-Wei Tang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Herpes Simplex Virus 1; DNA replication; DNA recombination; Transcription;

    Sammanfattning : Herpes simplex virus 1 (HSV-1) is one of nine different herpesvirus infecting man. They are all capable of establishing a life-long latent state following the primary infection. HSV-1 as well as other herpesviruses may reactivate from the latent state and give rise to a productive infection with clinical symptoms or asymptomatic shedding. LÄS MER

  7. 5. Characterization of the DNA-Binding Properties of the Cyanobacterial Transcription Factor NtcA

    Författare :Susanne Wisén; Bengt Mannervik; Enrique Flores; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; NtcA; transcription regulation; cyanobacteria; redox regulation; DNA binding; nitrogen fixation; Anabaena PCC 7120; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : Nitrogen is an essential building block of proteins and nucleic acids and, therefore, crucial for the biosphere. Nearly 79 % of the air consists of nitrogen, but in the form of nitrogen gas (N2), which cannot be utilized by most organisms. LÄS MER
