Heparin is known to efficiently attenuate metastasis in various tumour models by different mechanisms including inhibition of tumour cell contacts with soluble and cellular components such as inhibition of heparanase or P- and L-selectin. We recently showed that heparin efficiently binds to VLA-4 integrin in melanoma cells in vitro. Here we describe VLA-4 integrin as a mediator of melanoma metastasis...
The integrin VLA-4-mediated binding is important for the metastatic dissemination of melanoma cells. Recently we found that heparin possesses a binding capacity to VLA-4. This could contribute to the heparin function to attenuate metastasis in a selectin-dependent manner. Aiming to a purposive, anti-adhesive heparin application, structural requirements of heparin for VLA-4 recognition have to be elucidated...
