  1. 1. Quiescent cancer cells : Three-dimensional cell models for evaluation of new therapeutics

    Författare :Frida Ek; Mårten Fryknäs; Malin Jarvius; Rolf Larsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; cancer cell quiescence; dormancy; three-dimensional; multicellular tumor spheroids; model development; cancer pharmacology; mitochondria; OXPHOS; colorectal carcinoma; hepatocellular carcinoma; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Inadequate metabolic conditions in solid tumors lead to the formation of quiescent cancer cells that are suspended in a transient cell cycle arrest. When conditions change, quiescent cancer cells can re-enter the cell cycle and cause recurrence. LÄS MER

  2. 2. Dissecting the Microenvironment of Urothelial Bladder Cancer : Therapy, Modelling and Biomarkers

    Författare :Iliana Kyriaki Kerzeli; Sara Mangsbo; Tania de Gruijl; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immuno-oncology; Tumor immunology; MALT1 inhibition; Urothelial bladder cancer; Tumor microenvironment; Immunologi; Immunology; Oncology; Onkologi; Urologi; Urology;

    Sammanfattning : The complexity of the tumor microenvironment (TME) impacts therapy responses and the survival of cancer patients. The scope of this thesis is to study the effects of immune modulation on tumor-infiltrating leukocytes, and to explore the TME of urothelial cancer to provide the research society with new knowledge and potential therapeutic targets.

  3. 3. Molecular mechanisms of nerve-tumor interactions : the intersection of cancer and neurodevelopment

    Författare :Luz Maria Gonzalez-Castrillon; Sara I Wilson; Daniel Öhlund; Nisha D’Silva; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Perineural invasion; cancer; PDAC; axonogenesis; neurodevelopment; spinal cord; axon guidance; bioinformatics.; biomedical laboratory science; biomedicinsk laboratorievetenskap;

    Sammanfattning : A wide range of cancers throughout the body are characterized by high nerve density and invasion of cancer cells within the nerves, a process called perineural invasion (PNI). Work in the field has shown that blocking nerves in organs with tumors leads to improved disease outcomes suggesting that finding ways to block tumor nerves could lead to new treatment approaches.

  4. 4. Type IV collagen in breast and colorectal cancer : a potential biomarker of metastatic disease

    Författare :Moa Lindgren; Hanna Nyström; Ingrid Ljuslinder; Malin Sund; Kristian Pietras; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; colorectal liver metastases; breast cancer; breast cancer metastases; tumor marker; biomarker; stroma; type IV collagen;

    Sammanfattning : Background: Metastatic colorectal cancer (mCRC) and metastatic breast cancer (mBC) are two leading causes of cancer-related mortality worldwide. Early detection of metastatic disease is critical, and sensitive, easily accessed and cost-effective biomarkers that can diagnose mBC and mCRC at an early stage would have high clinical value.

  5. 5. Functional and Molecular Characterization of BRCA1 and BRCA2 Associated Breast Cancer

    Författare :Johan Vallon-Christersson; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; onkologi; cancer; Cytologi; cancerology; Cytology; BioArray Software Environment; BASE; Software; Open-source; Copy number; Gene expression; Microarray; BRCA2; BRCA1; Breast cancer; Hereditary cancer; oncology;

    Sammanfattning : This doctoral dissertation is based on five appended papers primarily concerned with three main topics, namely: the functional characterization of specific and clinically relevant perturbations found in BRCA1 ? one of the major breast cancer susceptibility genes; the use of microarray technologies for molecular characterization of hereditary breast tumor samples from a genomic perspective; and finally, the development of software to address some of the logistical problems of data analysis and management that arise when utilizing microarrays. Results obtained from the work presented herein demonstrate the following: that transcription az says can aid in the characterization of C-terminal missense mutations but that it may not be possible to unambiguously characterize variants with a yeast-based assay alone; that a naturally occurring C-terminal germline mutation in BRCA1 encodes a protein with apparent temperature-dependant functional properties; that open-source software can provide comprehensive solutions to meet data management needs of microarray experimenters; that BRCA1 and BRCA2 associated breast tumors exhibit markedly different copy number aberrations when compared to each other as well as to sporadic tumors; and that gene expression profiling in BRCA1 and BRCA2 associated breast tumors reveals specific gene expression patterns.
