  1. 1. Cellular interactions of HAMLET and their role in cell death

    Detta är en avhandling från Department of Microbiology, Immunology and Glycobiology, Lund University

    Författare :Maria Trulsson; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HAMLET; alpha-lactalbumin; cancer; cell death; ion channels; p38; cell detachment; alpha-actinin; endocytosis; macropinocytosis; c-Myc; glycolysis;

    Sammanfattning : HAMLET is a protein-lipid complex that selectively kills tumor cells. In this thesis, we identified new mechanisms, whereby HAMLET initiates and executes tumor cell death. HAMLET targets several cellular compartments ranging from the plasma membrane to the nucleus. LÄS MER

  2. 2. Regulation of Platelet-Derived Growth Factor Receptor Signaling and its Targeting in Cancer Therapy

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Haisha Ma; Johan Lennartsson; Håkan Axelson; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGF; PDGFR; Ras; macropinocytosis; Fer; STAT3; HD-PTP; Cbl; ubiquitination; pericyte; vasculature; tumor; ASKA; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Sammanfattning : Overactivity of platelet-derived growth factor receptor (PDGFR) is a frequent event in many types of solid tumors. Therefore, it is of great importance to uncover the mechanisms that regulate PDGF/PDGFR signalling, to develop efficient inhibitors targeting this pathway. LÄS MER

  3. 3. Cell-penetrating peptides in protein mimicry and oligonucleotide delivery Applications and mechanisms

    Detta är en avhandling från Stockholm : Institutionen för neurokemi

    Författare :Henrik Johansson; Ülo Langel; Michael Gait; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peptide; oligonucleotide; cell-penetrating peptide; PNA; splicing; MEDICINE Chemistry Neurochemistry; MEDICIN Kemi Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : The plasma membrane functions as a barrier, restricting entry of hydrophilic pharmaceutical agents. Cell-penetrating peptides (CPPs) are capable of transporting bioactive cargos into the cell and have consequently been extensively investigated for their mechanism of entry and capability to deliver various cargos spanning from peptides to plasmids.

  4. 4. Naturally derived cell-penetrating peptides and applications in gene regulation A study on internalization mechanisms and endosomal escape

    Detta är en avhandling från Stockholm : Institutionen för neurokemi

    Författare :Pontus Lundberg; Ülo Langel; Bernard Lebleu; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peptide; oligonucleotide; endocytosis; gene regulation; MEDICINE Chemistry Neurochemistry; MEDICIN Kemi Neurokemi;

    Sammanfattning : Cell-penetrating peptides are a class of peptides which have achieved a lot of recognition due to their vector abilities. Since their discovery over a decade ago, there has been an uncertainty concerning the mechanism by which they are internalized into the cells. LÄS MER

  5. 5. Vectorization of oligonucleotides with cell-penetrating peptides Characterization of uptake mechanisms and cytotoxicity

    Detta är en avhandling från Stockholm : Institutionen för neurokemi

    Författare :Samir EL Andaloussi; Ülo Langel; Alain Prochiantz; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CPP; endocytosis; splice correction; siRNA; PNA; cargo delivery; M918; MEDICINE Chemistry Neurochemistry; MEDICIN Kemi Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : The hydrophobic plasma membrane constitutes an indispensable barrier for cells in living animals. Albeit being pivotal for the maintenance of cells, the inability to cross the plasma membrane is still one of the major obstacles to overcome in order to progress current drug development. LÄS MER
