Endothelial cell specific antibodies and uses thereof
Methods and composition provided herein relate to the inhibition of proliferation, migration, and tubule formation of cells and are thus useful in treating angiogenesis associated diseases, including cancer, polycystic kidney disease, diabetic retinopathy, rheumatoid arthritis, and psoriasis. Disclosed are methods of inhibiting endothelial cell proliferation, migration, and tubule formation by administering an antibody specific for Tumor EndothPelial Markers (TEMs). Also disclosed are methods of inhibiting angiogenesis and tumor growth by administering a TEM-specific antibody and antibody compositions useful in such methods.
1 - 138 . (canceled)
139 . A method of inhibiting proliferation in a cell, comprising: administering an effective amount of an antibody, or a biologically active fragment thereof, which specifically binds to an antigen selected from the group consisting of Tumor Endothelial Marker (TEM) 1 and TEM 17,
whereby the antibody inhibits proliferation in the cell.
140 . A method of inhibiting migration of a cell, comprising: administering an effective amount of an antibody, or a biologically active fragment thereof, which specifically binds to an antigen selected from the group consisting of TEM 1, TEM 17, and TEM 9,
whereby the antibody inhibits migration of a cell.
141 . A method of inhibiting endothelial tube formation, comprising: administering an effective amount of an antibody, or a biologically active fragment thereof, which specifically binds to an antigen selected from the group consisting of TEM 1 and TEM 17,
whereby the antibody inhibits endothelial tube formation.
142 . A method of inhibiting angiogenesis, comprising: administering to a subject in need thereof, an effective amount of an antibody, or a biologically active fragment thereof, which specifically binds to an antigen selected from the group consisting of TEM 1, TEM 17, and TEM 9,
whereby the antibody inhibits angiogenesis.
143 . The method of claim 142 , wherein the angiogenesis is neoangiogenesis.
144 . The method of claim 142 , wherein the antibody is conjugated to an antiangiogenic agent or an antitumor agent.
145 . A method of inhibiting tumor growth, comprising: administering to a subject in need thereof, an effective amount of an antibody, or a biologically active fragment thereof, which specifically binds to an antigen selected from the group consisting of TEM 1, TEM 17, and TEM 9,
whereby the antibody inhibits the tumor growth.
146 . The method of claim 145 , wherein the antibody is conjugated to an antitumor agent or an antiangiogenic agent.
147 . The method of claim 145 , wherein the tumor is an adenocarcinoma, leukemia, lymphoma, melanoma, sarcoma, or tetratocarcinoma.
148 . The method of claim 145 , wherein the tumor is a cancer of the adrenal gland, bladder, bone, bone marrow, brain, breast, cervix, gall bladder, ganglia, gastrointestinal tract, heart, kidney, liver, lung, muscle, ovary, pancreas, parathyroid, penis, prostate, salivary glands, skin, spleen, testis, thymus, thyroid, or uterus.
