  1. 1. Regulation of TGFβ signaling by long non-coding RNAs and ADP-ribosylation

    Författare :Panagiotis Papoutsoglou; Aristidis Moustakas; Carl-Henrik Heldin; Peter Zaphiropoulos; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGFβ; signal transduction; long non-coding RNAs; ADP-ribosylation; transcriptional regulation; chromatin remodeling; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Transforming growth factor β (TGFβ) signaling pathways participate in embryonic development and tissue homeostasis and have a dual role in cancer. TGFβ acts as a tumor suppressor that promotes cell cycle arrest and apoptosis at initial stages of tumorigenesis. LÄS MER

  3. 2. Cellular targets of Pseudomonas aeruginosa toxin Exoenzyme S

    Författare :Maria Henriksson; Bengt Hallberg; Lars Rönnstrand; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Pseudomonas aeruginosa; ADP-ribosylation; GAP; Ras superfamily; NAD; ExoS; 14-3-3; Cellbiologi; Cell biology; Cellbiologi; molecular cell biology; molekylär cellbiologi;

    Sammanfattning : Pseudomonas aeruginosa is an opportunistic pathogen that can cause life-threatening infections in immunocompromised patients. It uses a type III secretion dependent mechanism to translocate toxic effector proteins directly into the eukaryotic cell. LÄS MER

  4. 3. Molecular mechanisms underlying the activation of ALC1 nucleosome remodeling

    Författare :Luka Bacic; Sebastian Deindl; Stefan D. Knight; Lari Lehtiö; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ALC1; CHD1L; nucleosome; ADP-ribosylation; chromatin; remodeling; PARP1; HPF1; DNA damage; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Sammanfattning : Packaging DNA into chromatin represses essential DNA-based processes, such as transcription, DNA replication, and repair. To change the accessibility of DNA, cells have evolved a set of enzymes referred to as chromatin remodelers that act on the basic repeat unit of chromatin,  the nucleosome. LÄS MER

  5. 4. Regulation of TGF-β Signaling by Post-Translational Modifications

    Författare :Peter Lönn; Aristidis Moustakas; Carl-Henrik Heldin; Petra Knaus; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TGF-β; Smad; PARP-1; PARG; ALK5; SIK; signal transduction; transcription; post-translational modification; phosphorylation; ubiquitin; ADP-ribosylation; DNA-binding; receptor degradation; Cell and molecular biology; Cell- och molekylärbiologi; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Sammanfattning : Transforming growth factor-β (TGF-β) signaling is initiated when the ligand binds to type II and type I serine/threonine kinase receptors at the cell surface. Activated TGF-β type I receptors phosphorylate R-Smads which relocate, together with co-Smads, to the cell nucleus and regulate transcription. LÄS MER

  7. 5. Allosteric control of ALC1-catalyzed nucleosome remodeling

    Författare :Laura C. Lehmann; Sebastian Deindl; Stefan D. Knight; Felix Müller-Planitz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ALC1; CHD1L; ATP-dependent chromatin remodeling; nucleosome; allosteric regulation; autoinhibition; macro domain; PARP; ADP-ribosylation; DNA damage; acidic patch; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Sammanfattning : The genetic information of eukaryotic cells is packaged inside the nucleus as chromatin. This packaging restricts access to the DNA and therefore represents a barrier for processes such as DNA replication, repair, and gene expression. LÄS MER
