520 | a The plasma protein histidine-rich glycoprotein (HRG) affects the morphology and function of both endothelial cells (ECs) and monocytes/macrophages in cancer. Here, we examined the mechanism of action of HRG's effect on ECs. HRG suppressed adhesion, spreading and migration of ECs specifically on collagen I (COL I) whereas ECs seeded on other extracellular matrix proteins were insensitive to HRG. HRG did not bind specifically to COL I or to the α-integrin binding site on collagen, GFOGER. Furthermore, HRG's inhibition of EC adhesion was not dependent upon heparan sulfate (HS) moieties as heparitinase-treated ECs remained sensitive to HRG. C2C12 cells expressing α2 integrin, the major collagen-binding α-integrin subunit in ECs, showed increased binding of HRG compared with wild type C2C12 cells lacking the α2 subunit. Recombinant α2 I-domain protein bound HRG and to a higher extent when in active conformation. However, the α2 I-domain bound weakly to HRG compared with COL I and the purified α2β1 ectodomain complex failed to retain HRG. We conclude that HRG binds to α2 integrin through low-affinity interactions in a HS-independent manner, thereby blocking EC-adhesion to COL I. | |
