The invention relates to a method of treatment for states related to inhibition of angiogenesis and endothelial cell proliferation comprising administering an effective amount of vimentin or its derivatives or its fragments, to a subject in need thereof. Further, the invention relates to a pharmaceutical composition and a medicament comprising vimentin, as well as the use of vimentin in the manufacture of a medicament. Hereby, angiogenesis and endothelial cell proliferation can be controlled, and therapeutic treatment for related states is provided.

Methods of using vimentin to inhibit angiogenesis and endothelial cell proliferation

Soluble recombinant CD44 hyaluronic acid binding domain (CD44HABD) inhibits angiogenesis in vivo in chick and mouse and thereby inhibits human tumor growth of various origins. The anti-angiogenic effect of CD44-HABD is independent of hyaluronic acid (HA) binding, since non-HA-binding mutants of CD44HABD still maintain anti-angiogenic properties. The invention discloses soluble non glycosylated CD44 recombinant proteins as a novel class of angiogenesis inhibitors based on targeting of vascular cell surface receptor. A method of block of angiogenesis and treatment of human tumors using recombinant CD44 proteins as well as their analogues is disclosed. As a further embodiment of the invention, methods for screening for new drug targets using CD44 recombinant proteins and their analogues are presented.
