TACI AS AN ANTI-TUMOR AGENT
A method of treating a mammal for a condition associated with undesired cell proliferation comprising administering to said mammal an effective amount of a TACI reagent, wherein said reagent extends mean survival time of said mammal by about 10% or more as compared to the absence of administering the TACI reagent.
1 . A method of reducing the size of a tumor located on or in a mammal comprising administering a polypeptide to the mammal having the tumor, wherein the polypeptide comprises a sequence that specifically binds to APRIL and shares at least 95% sequence identity with SEQ ID NO:1, and wherein administering the polypeptide reduces the size of the tumor.
2 . The method of claim 1 , wherein the polypeptide comprises an immunoglobulin polypeptide.
3 . The method of claim 2 , wherein the immunoglobulin polypeptide is an Fc domain.
4 . The method of claim 3 , wherein the Fc domain is an IgG Fc domain.
5 . The method of claim 2 , wherein the polypeptide comprises a sequence selected from the group consisting of:
(a) amino acid residues 1-166 of SEQ ID NO:1;
(b) amino acid residues 1-160 of SEQ ID NO:1;
(c) amino acid residues 1-114 of SEQ ID NO:1; and
(d) amino acid residues 32-114 of SEQ ID NO:1.
6 . The method of claim 1 wherein the polypeptide is administered via an intravenous, intraperitoneal, subcutaneous or intramuscular route.
7 . The method of claim 1 wherein the tumor is a cancer selected from the group consisting of: renal cell cancer, Kaposi's sarcoma, breast cancer, sarcoma, ovarian carcinoma, rectal cancer, throat cancer, melanoma, colon cancer, bladder cancer, mastocytoma, lung cancer, mammary adenocarcinoma, pharyngeal squamous cell carcinoma, gastrointestinal cancer, and stomach cancer.
8 . A method of reducing the size of a tumor located on or in a mammal comprising administering a polypeptide to the mammal having the tumor, wherein the polypeptide comprises a fragment of amino acids 1-166 of SEQ ID NO:1 that specifically binds to APRIL, and wherein administering the polypeptide reduces the size of the tumor.
9 . The method of claim 1 , wherein the wherein the polypeptide comprises amino acid residues 1-160 of SEQ ID NO:1.
10 . The method of claim 1 , wherein the wherein the polypeptide comprises amino acid residues 1-161 of SEQ ID NO:1.
11 . The method of claim 1 , wherein the wherein the polypeptide comprises amino acid residues 1-166 of SEQ ID NO:1.
12 . The method of claim 1 , wherein the wherein the polypeptide comprises amino acid residues 1-171 of SEQ ID NO:1.
