26. Role of Wnt-5a in breast cancer
Sammanfattning : Breast cancer is one of the most common cancer forms in the industrialized world. Only in Sweden, nearly 6000 women are diagnosed with breast cancer each year and 1/3 of them eventually succumb to the disease. LÄS MER
27. The cell biology and catalytic properties of the nutrient-induced signaling endoprotease Ssy5
Sammanfattning : Cells continuously sense and respond to changes in the presence, quality and quantity of external and internal nutrients. Specific signaling proteases have been identified based on their roles in processing or destruction of distinct sets of downstream effector proteins in response to environmental cues. LÄS MER
28. Cellular Resilience and Fragility in Response to Environmental and Gene Expression Perturbations
Sammanfattning : Cells are constantly subjected to perturbations. Whether these are extracellular or intracellular, they can be detrimental to cellular fitness. The cell has evolved elaborate systems and mechanisms that allow it to remain functional in the face of disturbances. LÄS MER
29. Alzheimer's disease mutations and cellular signalling
Sammanfattning : Alzheimer's disease is the most frequent cause of dementia in elderly and is characterised neuropathologically by the extracellular deposition of amyloid plaques (containing the 39-43 amino acid Abeta peptide), as well as intracellular neurofibrillary tangles (NFTs) composed primarily of an abnormally hyperphosphorylated form of the microtubule-associated protein tau. A proportion (10- 15%) of Alzheimer's disease cases is familial, the remainder being sporadic. LÄS MER
30. Signal transduction via ion fluxes : a cell imaging study with emphasis on calcium oscillations
Sammanfattning : Signal transduction via ion fluxes is of vital importance for all mammalian cells. Cells can exploit ion regulatory mechanisms to generate and transmit intracellular signals. Improvements in digital microscopic imaging technology have made it possible to explore micro-environments and complex intracellular machineries. LÄS MER
