1. Expression of ß-actin and human profilin in the yeast Saccharomyces cerevisiae : isolation and characterization of site-specific actin mutants
Sammanfattning : .... LÄS MER
2. Dietary fatty acids increase the absorption of toxic substances and drugs by modifying different absorption pathways in the intestinal epithelium
Sammanfattning : Dietary fatty acids have surface active properties comparable to substances used as absorption enhancers of poorly absorbed drugs. The intestinal epithelium serves as a gatekeeping barrier for the absorption of toxic substances, nutrients and drugs. LÄS MER
3. Receptor tyrosine kinase c-Kit signalling in hematopoietic progenitor cells
Sammanfattning : The receptor tyrosine kinase (RTK) c-Kit is expressed in hematopoietic stem and progenitor cells, mast cells and in several non-hematopoietic tissues. In the hematopoietic system c-Kit and its ligand Steel Factor (SF, aka Stem Cell Factor) are critical for proliferation, survival and differentiation. LÄS MER
4. Mechanisms for TGF-β-Mediated Regulation of the Actin Filament System and Apoptosis
Sammanfattning : Transforming growth factor-β (TGF-β) is a member of a large superfamily of cytokines which participate in many different types of cellular processes, such as growth inhibition, cell migration, differentiation, cell adhesion, wound healing and immunosuppression. Alterations of TGF-β superfamily signalling results in several different disorders, including bone disease, vascular disease and cancer. LÄS MER
5. Cell signaling by Rho and Miro GTPases : Studies of Rho GTPases in Cytoskeletal Reorganizations and of Miro GTPases in Mitochondrial Dynamics
Sammanfattning : The Ras superfamily of GTPases embraces six major branches of proteins: the Ras, Rab, Ran, Arf, Rho and Miro subfamilies. The majority of GTPases function as binary switches that cycle between active GTP-bound and inactive GDP-bound states. This thesis will focus primarily on the biological functions of the Rho and Miro proteins. LÄS MER
