  1. 1. Membrane Stress and the Role of GYF Domain Proteins

    Författare :Alexander Georgiev; Åke Wieslander; Hana Sychrova; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SYH1; SMY2; YPT6; RIC1; MYR1; processing bodies; vesicular trafficking; lipid bilayer; budding yeast; GYF; membrane stress; mRNA decay; Saccharomyces cerevisiae; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Intracellular membrane trafficking is regulated by a large number of protein complexes and lipids. Blocking of trafficking disrupts normal membrane dynamics and causes membrane stress. LÄS MER

  3. 2. β-cell dysfunction in Huntington's disease

    Författare :Karl Bacos; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolism; secretion; Insulin; trafficking; R6 2 mouse; granule; exocytosis; neurodegeneration; huntingtin;

    Sammanfattning : Huntington's disease (HD), a fatal neurodegenerative disorder, is associated with an increased risk of diabetes mellitus. The reason for this is unknown, but considering the functional similarities of neurons and the insulin secreting pancreatic β-cell, pathological mechanisms may be shared by both cell types and account for neuronal as well as endocrine dysfunction.

  4. 3. 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.

  5. 4. Identification and Characterization of Proteins and MicroRNAs that Modulate Receptor Signaling, Vesicular Trafficking and Cell Migration in Vascular Cells

    Författare :Johan Heldin; Johan Kreuger; Jonas Fuxe; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; cell migration; signaling; VEGF; FGD5; ExoC3L2; microRNA; RhoD; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Blood vessels deliver nutrients and oxygen to tissues. Importantly, the functions and growth of blood vessels are commonly altered in disease. The inside of all blood vessels are lined with endothelium, a thin specialized layer of endothelial cells that separate the blood from other tissues. LÄS MER

  7. 5. Regulation of GRAF1 membrane sculpting function during cell movement

    Författare :Monika K. Francis; Richard Lundmark; Pekka Lappalainen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocytosis; migration; polarisation; tension; CLIC GEEC; GRAF1; Rho GTPase; Cdc42; Rab8; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : All eukaryotic cells rely on endocytic events to satisfy a constant need for nutrient and fluid uptake from their surroundings. Endocytosis-dependent turnover of cell surface constituents also serves to control signal transduction and establish morphological changes in response to extracellular stimuli. LÄS MER
