Opis:
A novel affinity purification method for rapid isolation of vitronectin (VN) from human plasma is described. Recently we have used phage display technology to obtain clones expressing peptides with high binding activity for VN. The isolated "strong VN binders" were covalently coupled to CNBr-activated Sepharose. Human plasma was applied to the column and bound VN was eluted using 0.5 M acetic acid, giving purity exceeding 90%. The developed method is a convenient alternative to conventional antibody-antigen affinity chromatography techniques for purification of VN, as it offers low ligand cost, is rapid and ensures good protein recovery from human plasma.

Opis:
The metastatic transformation of melanocytes is associated with altered expression of adhesion molecules, including αvβ3 and α3β1 integrins. Integrin αvβ3 is a primary vitronectin (VN) receptor, while both integrin types take part in adhesion to VN when they are in complex with uPAR. Although their role in melanoma cell interaction with VN is of great interest, the influence of N-oligosaccharides attached to these glycoproteins is still unappreciated. The present study assesses the role of αvβ3 and α3β1 integrins and the influence of their glycosylation status on WM9 and WM239 metastatic melanoma cell interactions with VN. Cell adhesion to and migration on VN were selected as the studied cell behaviour parameters. Functionblocking antibodies and swainsonine (SW) treatment were used in these tests. Both cell lines interacted with VN in an integrin-mediated but cell-line-specific manner. In WM9 cells, migration was not completely inhibited by antibodies against α3β1 or αvβ3 integrins, suggesting the participation of other VN receptors. In both cell lines in coprecipitation test the formation of an integrins/uPAR complex was shown. In the presence of SW formation of the complex did not occur, suggesting the participation of glycosylation in this proccess. Additionally, the adhesion properties of WM9 cells were changed after SW treatment. Our results suggest that in these two metastatic cell lines integrin-linked N-oligosaccharides influence the VN adhesion receptor activity and function.
