1. 1. Studies of Mesenchymal Progenitor Cells and Tumour Growth, Integrins and Matrix Metalloproteinases

   Författare :Lars Bryngelsson Ohlsson; Immunologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; Tumour inhibition; cancer; onkologi; cancerology; Cytologi; oncology; Cytology; Biologi; Biology; Medicin människa och djur ; Medicine human and vertebrates ; Integrin matrix metalloproteinase interaction; Immunologi; serologi; transplantation; Proteins; enzymology; Proteiner; enzymologi; serology; Mesenchumal progenitor cells;

   Sammanfattning : In this thesis we characterize the effect of mesenchymal progenitor cells (MPCs) on tumour growth, and show that MPCs can have inhibitory effects on tumour development. We developed a method to subcutaneously transplant tumour cells, cultured in vitro in a pre-formed gelatin matrix, that made it possible to study the early phases of tumour development. LÄS MER

3. 2. Specific anti-tumour effects of 6-diazo-5-oxo-L-norleucine (DON) on carcinoid tumour cells

   Författare :Feng Wu; Uppsala universitet; []
   Nyckelord :Medical sciences; carcinoid tumour; diazo-oxo-L-norleucine; mitochondria; apoptosis; PET; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

   Sammanfattning : Glutamine is essential for cell growth. 6-diazo-5-oxo-L-norleucine (DON) is a rather old anti-tumour drug developed as a glutamine antagonist. Previous clinical trials with DON, not including carcinoid tumours, did not prove convincing. Hence the drug was not further used. LÄS MER

4. 3. The immunomodulatory properties of C-Med 100 an extract of the plant Uncaria tomentosa

   Författare :Christina Silver; Diabetes - immunovirologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunologi; serologi; serology; Immunology; survival; proliferation; inhibition; NF-kB; Uncaria tomentosa; quinic acid;

   Sammanfattning : Extracts from the bark of the vine Uncaria tomentosa have anti-inflammatory, antiviral, antimutagenic and antioxidant effects. In this study, we evaluate the effects of an Uncaria tomentosa extract, denoted C-Med 100, on the cellular level of the immune system both in vivo and in vitro. LÄS MER

5. 4. Experimental therapies of malignant glioma : with emphasis on angiogenesis inhibition

   Författare :Maria Sandström; Roger Henriksson; Mikael Johansson; Anja Smits; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glioma; angiogenesis; VEGF; tyrosinekinaseinhibitor; ZD6474; plasminogenactivator; tPA; uPA; proteomics; Oncology; Onkologi;

   Sammanfattning : Malignant glioma consists of a group of diseases where the localisation and the nature of the disease makes treatment an extreme challenge. Two important biological features of malignant glioma cells are their infiltrative growth and their ability to induce angiogenesis. LÄS MER

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

   Författare :Amelie Fondell; Lars Gedda; Detlef Gabel; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radionuclide; Auger electrons; liposomes; targeting; tumour therapy; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

   Sammanfattning : 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.
