Antiproliferative factor and methods of use
A novel antiproliferative factor comprising a glycopeptide is disclosed. In specific embodiments, the novel antiproliferative factor is associated with the bladder. Compositions, diagnostic kits and reagents, and methods of using the compounds for identifying and/or treating interstitial cystitis and cancer are disclosed.
1. A method of treating an individual for cancer, comprising the step of administering to the individual a therapeutically effective amount of a glycopeptide having one or more sugar moieties, wherein at least one sugar moiety is linked to a peptide moiety, wherein the peptide moiety comprises SEQ ID NO:3.
2. A method of treating an individual for cancer, comprising the step of administering to the individual a therapeutically effective amount of a glycopeptide having one or more sugar moieties, wherein at least one sugar moiety is linked to a peptide moiety, wherein the peptide moiety comprises SEQ ID NO:4.
3. A method of treating an individual for cancer, comprising the step of administering to the individual a therapeutically effective amount of a glycopeptide having one or more sugar moieties, wherein at least one sugar moiety is linked to a peptide moiety, wherein the peptide moiety comprises SEQ ID NO:5.
4. A method of treating an individual for cancer, comprising the step of administering to the individual a therapeutically effective amount of a glycopeptide having one or more sugar moieties, wherein at least one sugar moiety is linked to a peptide moiety, wherein there are two or three sugars that are O-linked to a serine or threonine, wherein there is a 1,3 or 1,4 linkage between two of the sugars, and wherein the peptide moiety comprises SEQ ID NO:3, SEQ ID NO:4, or SEQ ID NO:5.
5. A method of treating an individual for cancer, comprising the step of administering to the individual a therapeutically effective amount of a glycopeptide having one or more sugar moieties, wherein at least one sugar moiety is linked to a peptide moiety, wherein there are two or three sugars that are O-linked to a serine or threonine, wherein there is a 1,3 or 1,4 linkage between two of the sugars, and wherein the peptide moiety comprises SEQ ID NO:3, SEQ ID NO:4, or SEQ ID NO:5.
