  1. 1. Genetic Profiling in Soft Tissue Sarcoma

    Författare :Princy Francis; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; synovial sarcoma; prognosis; Cytology; SS18-SSX; intratumor heterogeneity; aCGH; array comparative genomic hybridization; gene expression analysis; microarray; cDNA; Soft tissue sarcoma; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : Soft tissue sarcomas (STS) are a heterogeneous group of highly malignant mesenchymal tumors that account for ~1% of all malignancies. Frequent heterogeneity and pleomorphism along with suboptimal diagnostic reproducibility and insufficient prognostic markers make clinical management of these tumors difficult. LÄS MER

  3. 2. DNA methylation profiling of CNS tumors; implications for clinical diagnostics

    Författare :Sandra Ferreyra Vega; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Central nervous system tumors; DNA methylation; clinical diagnostics; diffuse gliomas; meningiomas; heterogeneity;

    Sammanfattning : Diffuse gliomas and meningiomas are the most common primary tumors of the central nervous system (CNS) in adults and these tumors cause significant morbidity and mortality worldwide. Deregulation of the epigenetic mechanisms, e.g. LÄS MER

  4. 3. Somatic Genetic Variation in Children: from Mosaicism to Cancer

    Författare :Anders Valind; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Somatic Mosaicism; Cancer; Tumor heterogeneity; Neuroblastoma; Wilms Tumor; Rhabdomyosarcoma; Aneuploidy;

    Sammanfattning : This thesis concerns various aspects of somatic mosaicism and genetic intratumor heterogeneity in childhood cancer.In paper I, I show that aneuploidy in itself does not lead to the level of chromosomal instability that is typically seen in malignant cells. This finding strongly argues against the so called autocatalytic theory of carcinogenesis. LÄS MER

  5. 4. Exploring Biological Systems using Spatial Transcriptomic Technologies

    Författare :Kim Thrane; Joakim Lundeberg; Patrik Ståhl; Ulf Gyllensten; KTH; []
    Nyckelord :Spatial Transcriptomics; single-cell RNA-seq; scRNA-seq; spatial VDJ; Spatial Isoform Transcriptomics; Biotechnology; Bioteknologi;

    Sammanfattning : The transcriptome and the cells’ spatial organization are important determinants for the functions of biological systems, such as a tumor, brain, or skin tissue. Single-cell RNA sequencing (scRNA-seq) has emerged as a powerful tool for profiling the transcriptome of individual cells. LÄS MER

  7. 5. Molecular Subtypes of Melanoma. Biological and Clinical Significance

    Författare :Helena Cirenajwis; Bröstcancer-genetik; []
    Nyckelord :Melanoma; molecular subtypes; gene expression; next generation sequencing;

    Sammanfattning : Cutaneous malignant melanoma (CMM) is the most lethal form of skin cancer and its incidence has increased faster than that of any other cancer, rendering it a major public health problem worldwide. High-throughput screenings have opened the door to a new scientific world, which enables molecular-based characterization of large cancer cohort collections. LÄS MER
