  1. 21. lac of Time : Transcription Factor Kinetics in Living Cells

    Författare :Petter Hammar; Johan Elf; Antoine van Oijen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gene regulation; transcription factor; lac operon; facilitated diffusion; single molecule imaging; Molecular Biotechnology; Molekylär bioteknik;

    Sammanfattning : Gene regulation mediated by transcription factors (TFs) is essential for all organisms. The functionality of TFs can largely be described by the fraction of time they occupy their regulatory binding sites on the chromosome. DNA-binding proteins have been shown to find their targets through facilitated diffusion in vitro. LÄS MER

    Sammanfattning : With accellerating global warming and pollution problems a change of energy regime is necessary. Solar energy offers a clean and unlimited energy source of enormous potential. Due to it’s intermittenet nature solar energy must be stored - ideally in the chemical bond of a carrier molecule. LÄS MER

  5. 24. Regulation of HIV-1 provirus transcription

    Författare :Mojgan H Naghavi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Key words- HIV-1; LTR; transcription; subtypes; phylogenetic analysis; NFkappaB; USF; MCEF; HMG-1 DSP1; Dorsal.;

    Sammanfattning : Transcription of the HIV-genome is regulated by the interaction of viral long terminal repeat (LTR) cis-acting sequences with a complex of viral regulatory proteins and cellular transcription factors. The complex interplay between the cellular-, and/or viral proteins and LTR of different subtypes may play a role in the control of HIV-1 latency versus activation. LÄS MER

  7. 25. An analytical framework for studying transcriptional regulation

    Författare :Christoph Sebastian Börlin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transcription factor; ChIP-exo; S. cerevisiae; transcriptional regulation;

    Sammanfattning : The state and behavior of any living cell is controlled by a complex interplay of different regulatory processes, with the regulation of transcription playing a major role. When a cell adapts to a new environment it often does that by modulating gene transcript levels, mainly through changes in transcription factor binding events. LÄS MER
