  1. 16. Gene regulation during development by chromatin and the Super Elongation Complex

    Författare :Olle Dahlberg; Mattias Mannervik; Peter Gergen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila development; gene regulation; transcription; chromatin; P-TEFb; Super Elongation Complex; KDM4A; H3K36me3; H3K14ac; histone replacement; utvecklingsbiologi; Developmental Biology;

    Sammanfattning : Developmental processes are carefully controlled at the level of transcription to ensure that the fertilized egg develops into an adult organism. The mechanisms that controls transcription of protein-coding genes ultimately ensure that the Pol II machine synthesizes mRNA from the correct set of genes in every cell type. LÄS MER

  2. 17. Calcium regulation and functions of basic Helix-Loop-Helix transcription factors

    Författare :Juha Saarikettu; Thomas Grundström; Dan Holmberg; Mikael Sigvardsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; calcium; calmodulin; calretinin; transcription; bHLH; E-protein; E2-2; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The members of the ubiquitously expressed E-protein subfamily of basic Helix-Loop-Helix (bHLH) transcription factors, E12/E47, SEF2-1 and HEB, have important roles as regulators of gene expression in various differentiation processes, including lymphocyte development and myogenesis. In myogenesis, E-proteins are proposed to function as obligate heterodimer partners for members of the MyoD family of muscle-specific bHLH transcription factors. LÄS MER

  3. 18. 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

  4. 19. Regulation of the Cyanobacterial Bidirectional Hydrogenase

    Författare :Paulo Oliveira; Peter Lindblad; Aaron Kaplan; Uppsala universitet; []
    Nyckelord :Biology; Biohydrogen; Cyanobacteria; Synechocystis; Anabaena Nostoc; Bidirectional hydrogenase; Transcription regulation; LexA; AbrB-like protein; Biologi;

    Sammanfattning : Today, mankind faces a new challenge in energetic terms: a new Industrial Revolution is imperative, already called by some as an Energetic Revolution. This corresponds to a conversion to clean, environmentally friendly and renewable energy sources. LÄS MER

  5. 20. Regulation of NF-κB by Calmodulin

    Författare :Åsa Antonsson; Thomas Grundström; Ylva Engström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; NF-κB; calmodulin; transcription; calcium; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Cells experience numerous external signals which they must respond to. Such signals arriving at the cell surface are transduced via various signal transduction pathways and often ultimately result in regulation of transcription. LÄS MER
