Abstract:
The CXC chemokine platelet factor 4 (PF4) appears to inhibit tumour growth through its modulation of the activity of angiogenic growth factors. We investigated the heparan sulphate-dependent mechanism of PF4 inhibition of fibroblast growth factor 2 (FGF-2). The ability of PF4 to bind simultaneously to both FGF-2 and HS was assessed using affinity gel chromatography. Thirty-three to forty-two percent more HS bound to the FGF-2 affinity gel in the presence of PF4 than with HS alone. Protection assays showed that PF4 and FGF-2 bound to adjacent or overlapping sites together covering a 12 kDa stretch of HS. This study suggests that the three components may form a ternary complex. PF4 released at sites of angiogenesis may bind to angiogenic growth factors attached to endothelial cell surface HS to disrupt or prevent them from interacting with their signalling receptors. Manipulation of this mechanism may prove useful for clinical intervention of angiogenesis.
