  • Patent number: 8017326
    Abstract: The present invention provides a method of identifying an effective agent that alters the association of a Bit1 polypeptide with an AES polypeptide. The method is practiced by contacting a Bit1 polypeptide, or active fragment thereof, and an AES polypeptide, or active fragment thereof, with an agent under conditions that allow the Bit1 polypeptide or active fragment thereof to associate with the AES polypeptide or active fragment thereof; and detecting an altered association of the Bit1 polypeptide or active fragment thereof and the AES polypeptide or active fragment thereof, where an altered association indicates that the agent is an effective agent that alters the association of a Bit1 polypeptide with an AES polypeptide. Such an effective agent can modulate apoptosis and can be a useful therapeutic agent.

  • Publication number: 20110165064
    Abstract: Disclosed are compositions and methods related to clot-binding compounds. For example, disclosed are compositions comprising a surface molecule and at least one modified clot-binding compound. The modified clot-binding compound can selectively bind to clotted plasma protein, wherein the composition causes clotting and amplifies the accumulation of the composition in tumors. The modified clot-binding compound can enhance the clotting in tumors compared to its unmodified derivative. The disclosed targeting is useful for treatment of cancer and other diseases and disorders.
