11. Extracellular Vesicles and RNA interference in tumors
Sammanfattning : Extracellular vesicles (EVs) including apoptotic bodies (ABs), microvesicles (MVs), exosomes (EXOs) and cell derived artificial nanovesicles (NVs) are important mediators of cell-to-cell communication, in part by transferring bioactive molecules such as DNA, mRNA, miRNA, siRNA, proteins, and lipids. These EVs are released by many cell types, including melanoma cells, and are found in many body fluids. LÄS MER
12. Soft Tissue Sarcoma Patterns multiplicity, heterogeneity and growth characteristics
Sammanfattning : Soft tissue sarcomas (STS) represent a group of rare and heterogenous tumors that optimally should be diagnosed and treated within multidisciplinary teams. This thesis has studied various aspects ? pathological, genetical, and clinical ? of STS. LÄS MER
13. Cell cycle regulatory genes in human astrocytic tumors
Sammanfattning : Cancer is a genetic disorder of somatic cells. Neoplastic transformation and malignant progression may be a consequence of accumulated multiple genetic changes in a cell. Astrocytic gliomas are the commonest brain tumors in humans. LÄS MER
14. Integrative genomic and survival analysis of breast tumors
Sammanfattning : With the continued accumulation of genomic data at ever increasing resolution the challenge ahead lies in reading out meaningful clinical/biological information form the data that can contribute to a better understanding of the cancerous process. The need for novel approaches, new statistical methods is therefore strong. LÄS MER
15. Epigenetic Regulation of Gene Transcription in Hematopoietic Tumors
Sammanfattning : Epigenetic modifications were shown to play an essential role in tumorigenesis. Epigenetic mechanisms can alter transcription in several ways, through DNA methylation and/or through histone modification. DNA methylation at the TSS (transcriptional start site) has been implicated in tumor development and gene silencing. LÄS MER
