  1. 21. RICH-1, a Multifunctional RhoGAP Domain-containing Protein, Involved in Regulation of the Actin Filament System and Membrane-trafficking

    Författare :Ninna Richnau; Pontus Aspenström; Carl-Henrik Heldin; Bengt Hallberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Rho GTPase; RhoGAP; actin; BAR domain; membrane-trafficking; formin homology proteins; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : The Rho GTPases, which are related to the Ras family of proto-oncogenes, have been found to have important roles in regulating the morphogenic and migratory properties of eukaryotic cells. In addition, these proteins have been shown to regulate aspects of cell signaling, cell growth, cell division and cell survival. LÄS MER

  3. 22. Novel roles of ErbB3 receptor tyrosine kinase in vesicular trafficking

    Författare :Ana Rosa Saez-Ibañez; Ingvar Ferby; Carl-Henrik Heldin; Johanna Ivaska; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ErbB3; Integrin; GGA3; Rabaptin5; PKD; Ack1; endocytic recycling; exosome; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Sammanfattning : ErbB3 is a catalytically impaired receptor tyrosine kinase (RTK) from the EGFR family. Upon ligand binding, ErbB3 forms heterodimers with other members of the family and triggers phosphorylation cascades that promote crucial cellular functions as proliferation, differentiation and survival.

  4. 23. Mechanisms of modulation of PDGFRβ signaling

    Författare :Niki Sarri; Carl-Henrik Heldin; Bengt Hallberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGF signalling; phosphatase; MKP2; DUSP4; deubiquitinase; USP4; USP17; E3 ligase; Cbl; TRIM21; endoribonuclease; G3BP1; Medicinsk biokemi; Medical Biochemistry; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Platelet-derived growth factors (PDGF) constitute a family of five functional dimers that bind to two structurally related tyrosine kinase receptors i.e. PDGF receptor α and β (PDGFRα and PDGFRβ, respectively), controlling cell growth, proliferation, and migration in cells of mesenchymal origin.

  5. 24. TRAF6, a key regulator of TGFβ-induced oncogenesis in prostate cancer

    Författare :Reshma Sundar; Marene Landström; Carl-Henrik Heldin; Petra Knaus; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TβRI; TGFβ; TACE; TRAF6; PS1; PKCζ; TβRI-ICD; NICD; Smad; non-Smad; prostate cancer; Snail1; MMP; p300; p21; PAI1; ubiquitination; cleavage; ICD; invasion; HES1; signaling; patologi; Pathology;

    Sammanfattning : Prostate cancer is the most common cancer in men, with the incidence rapidly increasing in Europe over the past two decades. Reliable biomarkers for prostate cancer are currently unavailable. Thus, there is an urgent need for improved biomarkers to diagnose prostate cancer at an early stage and to determine the best treatment options. LÄS MER

  7. 25. Transcriptional and Epigenetic Regulation of Epithelial-Mesenchymal Transition

    Författare :E-Jean Tan; Aristidis Moustakas; Carl-Henrik Heldin; Geert Berx; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGFβ; EMT; HMGA2; Snail; Twist; E-cadherin; epigenetics; invasion; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : The transforming growth factor beta (TGFβ) is a cytokine that regulates a plethora of cellular processes such as cell proliferation, differentiation, migration and apoptosis. TGFβ signals via serine/threonine kinase receptors and activates the Smads to regulate gene expression. LÄS MER
