21. Cyclin E overexpression and associated events in human breast cancer
Sammanfattning : Unrestrained proliferation is a hallmark of cancer and genetic defects within G1/S-phase regulation and the pRb pathway occur frequently. Proliferation control can be circumvented either by excess cyclin D1 or cyclin E, alterations that can define two alternative tumour biologic pathways in breast cancer. LÄS MER
22. Alpha 1-antitrypsin: A Role in Cancer Progression
Sammanfattning : Alpha1-antitrypsin (AAT), a circulating single-chain glycoprotein is the most abundant serine proteinase inhibitor in human plasma. AAT is an acute phase protein, its levels increase rapidly to concentrations exceeding 50mM in response to inflammation, infection and malignant diseases. LÄS MER

24. The Invasion of the Zebra Mussel - Effects on Phytoplankton Community Structure and Ecosystem Function
Sammanfattning : Biological invasion has become a major threat to economy, ecology, global biodiversity and ecosystem function of aquatic ecosystems. The main aim of the thesis was to study the effects of the zebra mussel (Dreissena polymorpha), a versatile invasive species, on phytoplankton dynamics and ecosystem function of lakes. LÄS MER
