  1. 1. Tumour Targeting Using Radiolabelled EGF Conjugates Preclinical Studies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Åsa Liljegren Sundberg; Uppsala universitet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; targeting; tumour; EGF; radionuclide; gefitinib; Iressa; ZD1839; glioma; therapy; diagnostics; Strålningsvetenskap; MEDICINE Physiology and pharmacology Radiological research Radiation biology; MEDICIN Fysiologi och farmakologi Radiologisk forskning Strålningsbiologi;

    Abstract : Tumour targeted radiotherapy is an appealing approach for treatment of disseminated tumour cells. A targeting agent that specifically binds to a structure on tumour cells is then used to transport therapeutically relevant radionuclides. The epidermal growth factor receptor, EGFR, is overexpressed on tumour cells in several malignancies, e.g. READ MORE

  2. 2. EGFR- and HER2-Binding Affibody Molecules Cellular studies of monomeric, dimeric and bispecific ligands

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lina Ekerljung; Uppsala universitet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EGFR; HER2; Affibody molecule; cell signaling; receptor dimerization; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

    Abstract : Abnormal expression and signaling of the ErbB receptors is associated with the development and progression of several forms of cancer. In this thesis, new ErbB-targeting affibody molecules are evaluated regarding their cellular effects in vitro. READ MORE

  3. 3. Two-Step Targeting for Effective Radionuclide Therapy Preclinical Evaluation of 125I-labelled Anthracycline Delivered by Tumour Targeting Liposomes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Amelie Fondell; Uppsala universitet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radionuclide; Auger electrons; liposomes; targeting; tumour therapy; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

    Abstract : For the treatment of cancer, Auger-electron emitting radionuclides are strongly dependent on their close proximity to DNA to utilize the local therapeutic potential of the Auger electrons. This thesis investigates a two-step targeting approach that uses targeting liposomes for the delivery of an Auger-electron emitter, 125I, coupled to a DNA-binding compound, Comp1, to the tumour-cell DNA.

  4. 4. Radiation response in human cells DNA damage formation, repair and signaling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ann-Sofie Gustafsson; Uppsala universitet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA damage; DNA repair; DSB; NHEJ; DNA-PK; ionizing radiation; heat-labile sites; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

    Abstract : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. READ MORE

  5. 5. Development of Affibody molecules for radionuclide molecular imaging and therapy of cancer

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hadis Honarvar; Uppsala universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Affibody molecules; HER2; Molecular imaging; Radionuclide targeted therapy; Radionuclide molecular imaging; Labeling chemistry; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

    Abstract : Affibody molecules are a promising class of scaffold-based targeting proteins for radionuclide-based imaging and therapy of cancer. This thesis work is based on 5 original research articles (papers I-V), which focus on optimization of molecular design of HER2-binding Affibody variants for high contrast imaging of this predictive biomarker as well as development of Affibody molecules suitable for radionuclide-based targeted therapies.
