DMP1 and neoplasm: Meanwhile the expression of DMP1, a member of the small integrin-binding ligand N-linked glycoproteins (SIBLINGs) that is involved in phosphatemia regulation, was only stimulated by PC3c cells conditioned media which, combined with the expression of type I collagen by the tumor cells, may contribute to the formation of the new bone mineralized matrix observed in vivo and by infrared microspectroscopy [36,37].
