title: Apolipoprotein E (ApoE), a novel heparin-binding protein inhibits the development of Kaposi's sarcoma-like lesions in BALB/c nu/nu mice.
abstract: Recombinant apolipoprotein E-3 (ApoE-3), expressed in Escherichia coli, was purified and used in an in vitro and an in vivo model system for acquired immunodeficiency syndrome-associated Kaposi's sarcoma (AIDS-KS). This protein blocked cell proliferation and chemotaxis of AIDS-KS cells in response to activated lymphocyte conditioned medium (AL-CM) and oncostatin M (OSM). ApoE-3 also inhibited the formation of neoangiogenic lesions induced in BALB/c nu/nu mice by AIDS-KS cells. These findings represent a novel and potentially less toxic therapeutic approach for the treatment of AIDS-KS.
