1. Biotic resistance in freshwater fish communities
Abstract : Invasions of non-native species cause problems in ecosystems worldwide, and despite the extensive effort that has been put into research about invasions, we still lack a good understanding for why some, but not other, communities resist these invasions. In this doctoral thesis I test hypotheses on biotic resistance using a large dataset of more than 1000 both failed and successful introductions of freshwater fish into Swedish lakes. READ MORE

2. Proteomics of invasiveness of human breast epithelial cells
Abstract : Mechanisms of malignant transformation and cancer invasion and factors controlling them in response to various stimuli remain elusive. We used proteomics and systems biology to explore these mechanisms in human breast epithelial cells. The objective has been to identify a set of biomarkers for diagnostics and prognostics of breast cancer. READ MORE

3. Micro-environmental control of tumor differentiation and invasiveness
Abstract : The transforming growth factor β (TGFβ) family participates in embryonic development and adult tissue homeostasis. In early stages of tumorigenesis, TGFβ promotes cell cycle arrest and apoptosis; however, in advanced malignancies, TGFβ promotes tumor cell migration and metastasis via the induction of epithelial-tomesenchymal transition (EMT).

4. A Novel Approach for Radiotherapy and Radiosurgery Treatment Planning Accounting for High-Grade Glioma Invasiveness into Normal Tissue
Abstract : High-grade gliomas (HGGs) are a type of malignant brain cancer, which include glioblastomas (GBMs). In adults, GBM is the most common malignant primary brain cancer. Attempts to treat patients with GBMs have been conducted for over a century, but the prognosis has only marginally improved. READ MORE

5. Molecular markers reflecting malignant transformation and tumor progression
Abstract : The early detection of neoplastic lesions is most critical in the successful treatment of malignant disease. This thesis investigates molecular targets for an improved detection and diagnosis of cancer by exploring the value of interphase fluorescence in situ hybridization (FISH) to detect specific chromosomal aneuploidies and gene amplifications, and laminin-5 gamma2 chain expression detected by immunohistochemistry as a marker for invasiveness.
