1. Role of extracellular retention of platelet-derived growth factor-B. Functions in development and disease
Sammanfattning : During development, the cell secretes growth and differentiation factors (GDFs) to the surrounding microenvironment. These factors are often key regulators of organogenesis and embryogenesis. Several GDFs carry sequences that mediate specific interaction with molecules of the extracellular matrix (ECM) that surrounds the cell. LÄS MER
2. Involvement of Heparan Sulphate Biosynthesis and Turnover in Cell Proliferation. A Novel Role for Nitric Oxide in Recycling of Heparan Sulphate Proteoglycans
Sammanfattning : The present investigation focuses on the role of HS metabolism in cell proliferation. The effect of the HS priming ß-D-xyloside, 2-(6-hydroxynaphthyl)-O-ß-D-xylopyranoside (Xyl-2-Nap-6-OH) on the proliferation of normal and transformed cells was studied. LÄS MER
3. Glypican-1: Structural and functional analysis of the N-glycosylated human protein
Sammanfattning : Glypicans are multifunctional cell surface heparan sulphate proteoglycans co-regulating numerous signalling pathways, and are thereby involved in the control of cellular division, differentiation, and morphogenesis. The heparan sulphate (HS) chains are responsible for many of those biological functions; nevertheless recent studies suggest functional roles for the glypican core proteins in mediating the signalling of various growth factors.

4. On the Role of Polyamines and Microvesicles in Tumour Development. Regulation by Hypoxia and Implications for Therapeutic Intervention of Cancer
Sammanfattning : Novel strategies for specific tumour cell targeting are necessary in order to improve survival rates and to reduce side effects of current therapies in cancer patients. Hypoxia is a hallmark of solid tumours and one of the major driving forces for tumour progression. LÄS MER
5. Studies on the role of Dally-like during Drosophila development
Sammanfattning : A cell is constantly subjected to cues from its surroundings in the form of signalling molecules e.g. Wingless (Wg), Insulin-like growth factor (IGF). As a result, important decisions regarding processes like growth, division, differentiation or migration are made. LÄS MER
