Molecular Basis of Adaptation of Enteroviruses to Different Cancer Cell Lines
… CVA9 also bind to heparan sulfate proteoglycans (HSPG). This thesis describes work designed to improve our understanding of CVA9 and echovirus cell/receptor tropism. Several echoviruses and CVA9 variants were tested in a panel of 9 cell lines. Distinct patterns of infection were seen, but did not …

Correlation of Heparan Sulfate Proteoglycan Structure and Metabolism With the Regulation of Cell Division
Heparan sulfate proteoglycan (HSPG), a ubiquitous cell surface component in animal cells, is a complex, polyanionic macromolecule consisting of a core protein to which are attached several heparan sulfate (HS) chains. Growing and confluent cultures of a rat hepatocyte cell line were labeled with …

The Regulation and Mechanism of Myelin Synthesis Involving Endogenous Steroid Hormones
… associated heparan sulfate proteoglycans (HSPG), surface competition experiments were performed with heparin and the basic peptide encoded by exon 6. Heparin and the exon 6 peptide were both found to dramatically inhibit the initiation of myelin formation. While these results are still …

Mechanisms of Molecular Chaperone Surface Binding and Endocytosis: Insights into the Molecular Basis for GRP94 Immune Function
… cell surface heparan sulfate proteoglycans (HSPGs) were identified as novel cell surface binding sites for GRP94.NTD on MEF cells. This conclusion was established using three distinct experimental approaches. GRP94.NTD surface binding was significantly decreased following heparin …

Vascular Endothelial Growth Factor In Cortical Development
… or absence of a heparin sulfate proteoglycan (HSPG) binding domain. Vegf isoforms with the full HSPG-binding domain are not diffusible in the microenvironment (Vegf188) without proteolytic cleavage, those with a partial HSPG-binding domain are partially diffusible (Vegf164), and those lacking …

Defining the role of heparan sulfate proteoglycans in APL-1 function in Caenorhabditis elegans
… target receptors. Heparin sulfate proteoglycans (HSPGs), such as LON-2 glypican and UNC-52 perlecan, are likely candidates for the ECM proteins that interact and guide sAPL-1. The disruption of APL-1 causes phenotypical changes, including in learning, reproduction, and memory; these defects are …

Heparan Sulfate Proteoglycans in Pancreatic Ductal Adenocarcinoma (PDAC)
… identified a heparan sulfate proteoglycan (HSPG), Syndecan-1 (SDC1), as a key effector for pancreatic ductal adenocarcinoma (PDAC) progression whose surface expression is driven by KRAS*. By leveraging various PDAC models, we found that surface SDC1 expression was initially diminished upon …

Design, Herstellungsoptimierung, Charakterisierung und Anwendung einer randomisierten, auf Adeno-assoziierten Viren exprimierten Peptidbank
… natürlichen Rezeptor Heparansulfat-Proteoglykan (HSPG) beteiligt ist. Dadurch wird einerseits die Bindung an HSPG abgeschwächt, andererseits ein neuer Bindungstropismus geschaffen. Ziel dieser Arbeit war die Herstellung einer "AAV-Kollektion", in der jedes Virus an der Oberfläche ein anderes, in …

Metabolism of Heparan Sulfate Proteoglycan in Rat Hepatocyte Cell Line and Its Role for Regulation of Cell Growth
… heparan sulfate proteoglycan (HSPG) was taken up by the cells and converted to free chains and about 10 percent of the internalized HS was transported into nucleus.

Syndecan-4 regulates cell-surface trafficking and biological activity of transglutaminase-2
… (Verderio et al., 2003). Hence HS proteoglycan (HSPG) could act as cell surface co-receptor for FNbound TG2 or contribute to the regulation of extracellular TG2 activity in cell adhesion and tissue repair.

The Heparan Sulfate Proteoglycan Perlecan Regulates Axonal and Synaptic Stability
Heparan sulfate proteoglycans (HSPGs) form essential components of the extracellular matrix (ECM) and basement membrane (BM) and have both structural and signaling roles. Perlecan is a secreted ECM-localized HSPG that contributes to tissue integrity and cell-cell communication. In this thesis, I …
