Patent number: 8334137Abstract: Identified herein is the location of the MN protein binding site, and MN proteins/polypeptides that compete for attachment to vertebrate cells with immobilized MN protein. Such MN proteins/polypeptides prevent cell-cell adhesion and the formation of intercellular contacts. The MN protein binding site is a therapeutic target that can be blocked by organic or inorganic molecules, preferably organic molecules, more preferably proteins/polypeptides that specifically bind to that site. Therapeutic methods for inhibiting the growth of preneoplastic/neoplastic vertebrate cells that abnormally express MN protein are disclosed. Vectors are provided that encode the variable domains of MN-specific antibodies and a flexible linker polypeptide separating those domains. Further vectors are disclosed that encode a cytotoxic protein/polypeptide operatively linked to the MN gene promoter or a MN gene promoter fragment comprising the HIF-1 consensus binding sequence, and which vectors preferably further encode a cytokine.Type: GrantFiled: December 17, 2010Date of Patent: December 18, 2012Assignee: Bayer Healthcare LLCInventors: Adrian L. Harris, Peter J. Ratcliffe

Publication number: 20090239247Abstract: The MN/CA IX protein is identified herein as a hypoxia marker. The MN/CA9 gene promoter is characterized, and the location of the HIF-1 binding site within the MN/CA9 promoter is identified. Further, the hypoxia inducibility of the MN/CA9 gene and the uses of such inducibility are disclosed. In one aspect, the invention provides diagnostic/prognostic tools for determining the presence of hypoxia in a tissue in a vertebrate, preferably a human, and for measuring the relative degree of hypoxia in said vertebrate. In another aspect, the invention provides methods using tumor biopsies to predict the radioresistance of a preneoplastic/neoplastic tissue in a vertebrate subject, preferably a human patient, for diseases in which MN/CA IX levels can be used to indicate radiobiologically relevant tumor hypoxia. Such predictive methods can be used as an aid in patient therapy selection.Type: ApplicationFiled: March 3, 2009Publication date: September 24, 2009Inventors: Adrian L. Harris, Peter J.
