11. Heparan Sulfate Regulation of Fibroblast Growth Factor (FGF) Receptor-1 Signal Transduction
Sammanfattning : Fibroblast growth factors (FGFs) constitute a family (currently FGF-1 to FGF-23) of polypeptides that are essential in embryonal development and adult physiology, in animals from nematodes to humans. FGFs bind to four receptor tyrosine kinases, denoted FGFR-1 to FGFR-4. LÄS MER
12. Fibroblast growth factor-induced signal transduction
Sammanfattning : Fibroblast growth factors (FGFs) evoke cellular responses by binding to FGF receptors (FGFRs). FGFRs are cell surface expressed membrane-spanning receptors with intrinsic stimulatable tyrosine kinase activity. This thesis describes the cell proliferation or differentiation. LÄS MER
13. Stem Cell Factor Induced Signal Transduction
Sammanfattning : Stem Cell Factor (SCF) can function as a survival factor, a mitogen or a chemoattractant depending on cell type. Binding of SCF to c-Kit induces dimerization and subsequent autophosphorylation of the receptor. This thesis describes the intracellular signal transduction elicited by c-Kit. LÄS MER
14. Robustness analysis of eukaryotic signal transduction with emphasis on the HOG pathway in Saccharomyces cerevisiae
Sammanfattning : Fundamental to life, in particular for unicellular microorganisms that generally are subjected to rapidly changing environmental parameters, is the need to monitor and integrate environmental stimuli with the internal cell status. The sensing of stimuli are typically initiated at the plasma membrane and then transmitted by means of intracellular signalling networks to elicit proper cellular responses. LÄS MER
15. Signal Transduction in Focal Cerebral Ischemia : Experimental Studies on VEGF, MAPK and Src family kinases
Sammanfattning : Cerebral ischemia elicits a wide range of events, including complex activation of various intracellular signaling pathways. This study aims to investigate the expression of vascular endothelial growth factor (VEGF) and the activation pattern of mitogen-activated protein kinases (MAPK) in reponse to focal cerebral ischemia.
