  1. 21. Molecular understanding of KRAS- and BRAF-mutated colorectal cancers

    Författare :Ida Lundberg; Richard Palmqvist; Maria Wikberg; Sofia Edin; Anita Sjölander; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; BRAF; KRAS; SOX2; CDX2; cancer stem cell; Th1 lymphocytes; miRNA; prognosis;

    Sammanfattning : Colorectal cancer (CRC) is the third most commonly diagnosed malignancy in both men and women, and one of the leading causes of cancer-related deaths worldwide. One frequently mutated pathway involved in oncogenesis in CRC is the RAS/RAF/MAP kinase pathway. LÄS MER

  3. 22. Mechanisms of survival and maintenance of Hematopoietic Stem Cells and Multipotent Progenitor Cells

    Författare :Richard Karlsson; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellulära vätskor; Hematologi; extracellular fluids; Haematology; hypoxia.; forkhead; Akt PKB; Bcl-2; apoptosis; Flt3; FL; c-kit; KL; cytokines; Hematopoiesis; progenitor;

    Sammanfattning : Hematopoietic stem cells and progenitor cells are maintained in the bone marrow microenvironment, where factors including soluble and membrane-bound cytokines influence the processes of self-renewal, proliferation and differentiation. Two nonreduntant cytokines with effects on hematopoiesis, Kit Ligand (KL) and Flt3 Ligand (FL), signal via related tyrosine kinase receptors, c-kit and Flt3. LÄS MER

  4. 23. Stem cell based therapy of malignant brain tumors

    Författare :Daniel Bexell; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural stem cell; pericyte; mesenchymal stem cell; neuroblast; subventricular zone; cancer stem cell; rat; glioma; cancer;

    Sammanfattning : Malignant brain tumor is a highly invasive and vascularized cancer. Current forms of therapy are not curative and can, at best, prolong survival for patients with this disease. The mean survival is only around 15 months. LÄS MER

  5. 24. Individually Tailored Toxicity-based Chemotherapy : Studies on Patients with Primary and Metastatic Breast Cancer

    Författare :Henrik Lindman; Jonas Bergh; Carl Blomqvist; Peter Nygren; Bo Nordenskjöld; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; breast cancer; tailored chemotherapy; toxicity-based dosing; high-dose therapy; MR imaging; G-CSF; epirubicin; docetaxel; cyclophosphamide; 5-fluorouracil; Onkologi; Oncology; Onkologi;

    Sammanfattning : Standard dosing of chemotherapy based on body surface area (BSA) results in large individual differences in toxicity due to a large inter-patient variability in pharmacokinetics (PK) and pharmacodynamics (PD). This results in under-dosing in certain patients with a potentially weaker antitumoral effect. LÄS MER

  7. 25. Tumor cell heterogeneity profiling using single-cell analysis

    Författare :Emma Jonasson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tumor heterogeneity; single-cell analysis; cancer stem cells;

    Sammanfattning : Cancer is a diverse disease with large variations between tumor types and patients regarding tumor progression and prognosis. Additionally, most individual tumors are heterogeneous, containing subpopulations of cells with various characteristics. LÄS MER
