11. Decoding Heparan Sulfate
Sammanfattning : Heparan sulfate (HS) is a polysaccharide of glycosaminoglycan type composed of alternating hexuronic acid [either glucuronic acid (GlcA) or iduronic acid (IdoA)] and glucosamine (GlcN) units that can be sulfated in various positions. HS binds to a large number of proteins and these interactions promote many biological processes, including cell adhesion and growth factor signaling. LÄS MER
12. Tumor Stroma in Anaplastic Thyroid Carcinoma : Interstitial Collagen and Tumor Interstitial Fluid Pressure
Sammanfattning : Anaplastic thyroid carcinoma (ATC) is an aggressive malignancy in man with stromal fibrosis as one of the main features. Carcinoma cells synthesized no or little collagen I protein. LÄS MER
13. Neural Stem and Progenitor Cells : Cellular Responses to Known and Novel Factors
Sammanfattning : Neural stem cell self-renewal and differentiation are tightly regulated events during CNS development, leading to cell division into new neural stem cells or the formation of neurons and glial cells. This thesis focuses on the cellular responses induced by known and novel factors in neural stem and progenitor cells (NSPCs). LÄS MER
14. The role of 1-intergrins in skeletal muscle differentiation and extracellular matrix assembly
Sammanfattning : Integrin subunit β1 forms heterodimeric receptors with at least 12 different α-subunits.These integrins are the main cellular receptors for extracellular matrix and they arenecessary for normal development. In this thesis, the effects of lack of integrin subunitβ1 on matrix deposition and on skeletal muscle development were studied. LÄS MER
15. Studies on the Differential Specificity of Protein Kinases and Its Applications
Sammanfattning : Protein kinases are enzymes that catalyse the phosphoryl transfer from the g-phosphate of ATP to acceptor amino acids in proteins. The specificity of selected model protein kinases was studied at three different levels using a) novel bi-substrate-analogue inhibitors, b) synthetic peptide substrates and c) mutated protein substrate analogues.
