  1. 1. Unravelling Mechanistic Insights of Eukaryotic Transcriptional Control

    Författare :Johanna Hörberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transcriptional control; Gene expression regulation; DNA supercoiling; DNA methylation; DNA-protein recognition; Basic-Leucine-Zipper transcription factors; Basic-Helix-Loop-Helix transcription factors; Sequence specific DNA plasticity; Transcription factor cooperativity; Cancer; Molecular modelling; Molecular dynamics;

    Sammanfattning : DNA transcription involves the association of multiple proteins with DNA to convert the genetic information into messenger-RNA transcripts, which later will be translated into proteins. Con-trolled regulation of transcription is imperative for preserving the healthy and homeostatic state of cells. LÄS MER

  3. 2. The Multifunctional HnRNP A1 Protein in the Regulation of the Cyp2a5 Gene : Connecting Transcriptional and Posttranscriptional Processes

    Författare :Tina Glisovic; Matti Lang; Francoise Raffalli-Mathieu; Lorenz Poellinger; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biochemistry; Cyp2a5; DNA-protein interaction; gene regulation; hnRNP A1; nucleocytoplasmic shuttling; RNA-protein interaction; RNA stabilization; posttranscriptional; transcriptional; Farmaceutisk biokemi; Pharmaceutical biochemistry; Farmaceutisk biokemi;

    Sammanfattning : The mouse xenobiotic-inducible Cyp2a5 gene is both transcriptionally and posttranscriptionally regulated. One of the most potent Cyp2a5 inducers, the hepatotoxin pyrazole, increases the CYP2A5 mRNA half-life. LÄS MER

  4. 3. Transcriptional control of CD4+ T lymphocytes

    Författare :Peter C J Janson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The immune system can respond to various types of pathogens such as bacteria, viruses, tumors and parasites. The ability to provide protection against different types of pathogens partly relies on development of alternative T effector cells with separate effector functions. LÄS MER

  5. 4. The Nucleosome as a Signal Carrying Unit : From Experimental Data to Combinatorial Models of Transcriptional Control

    Författare :Stefan Enroth; Jan Komorowski; Claes Wadelius; Rickard Sandberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Next generation sequencing; Nucleosome; Histone modification; Transcriptional regulation; Bioinformatics; Bioinformatik; Bioinformatics; Bioinformatik; Bioinformatik; Bioinformatics;

    Sammanfattning : The human genome consists of over 3 billion nucleotides and would be around 2 meters long if uncoiled and laid out. Each human somatic cell contains all this in their nucleus which is only around 5 µm across. This extreme compaction is largely achieved by wrapping the DNA around a histone octamer, the nucleosome.

  7. 5. Gene Regulatory Networks: Dynamics and Stability

    Författare :Carl Troein; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; systems; control; Datalogi; numerisk analys; system; kontroll; Computer science; numerical analysis; Fysik; biomathematics biometrics; Bioinformatik; medicinsk informatik; biomatematik; Physics; medical informatics; transcriptional regulation; gene regulatory networks; Bioinformatics; signaling pathway profiling; stem cell regulation; metabolic pathway; fitness; nested canalyzing rules; Kauffman networks; random Boolean networks; Fysicumarkivet:2007:Troein;

    Sammanfattning : Life as we know it is based on cells that use proteins and RNA to carry out metabolism, self-replication, and other essential tasks. The genes that code for these molecules are encoded in DNA, and through the processes of transcription and translation the cell expresses its genes. LÄS MER
