Nucleic acid and corresponding protein entitled 161P2F10B useful in treatment and detection of cancer
View Patent ↗A gene (designated 161P2F10B) and its encoded protein are described wherein 161P2F10B exhibits tissue specific expression in normal adult tissue, it is aberrantly expressed in the cancers listed in Table I. Consequently, 161P2F10B provides a diagnostic, prognostic, prophylactic and/or therapeutic target for cancer. The 161P2F10B gene or fragment thereof, or its encoded protein or a fragment thereof, can be used to elicit a humoral or cellular immune response.
1. A method of inhibiting growth of a solid tumor cell that expresses a protein, comprising: contacting said cell with an antibody or antigen-binding fragment thereof comprising an antigen-binding domain, wherein the antibody or antigen-binding fragment thereof specifically binds to the protein, wherein the protein comprises the amino acid sequence of SEQ ID NOS: 743 or 745, wherein the antibody or antigen-binding fragment thereof is conjugated to a cytotoxic agent, and wherein the antibody or antigen-binding fragment thereof binds to the protein on the tumor cell; and inhibiting the growth of the tumor cell to which the antibody or fragment thereof is bound, wherein the solid tumor is selected from the group consisting of breast, lung, ovary, pancreas and prostate.
2. The method of claim 1 , wherein the solid tumor is a breast tumor.
3. The method of claim 1 , wherein the solid tumor is an ovarian tumor.
4. The method of claim 1 , wherein the solid tumor is a pancreas tumor.
5. The method of claim 1 , wherein the solid tumor is a prostate tumor.
6. The method of claim 1 , wherein the antibody is a monoclonal antibody.
7. The method of claim 6 , wherein the monoclonal antibody is recombinantly produced.
8. The method of claim 7 , wherein the antibody is a single chain antibody.
9. The method of claim 1 , wherein the antigen-binding fragment thereof is selected from the group consisting of Fab, F(ab′) 2 and Fv fragment.
10. The method of claim 1 , wherein the antibody is a human antibody, a humanized antibody or a chimeric antibody.
11. The method of claim 1 , wherein the agent is selected from the group consisting of a radioactive isotope, a chemotherapeutic agent and a toxin.
12. The method of claim 11 , wherein the radioactive isotope is selected from the group consisting of 211 At, 131 I, 125 I, 90 Y, 186 Re, 188 Re, 153 Sm, 212 Bi, 32 P and a radioactive isotope of Lu.
13. The method of claim 11 , wherein the chemotherapeutic agent is selected from the group consisting of paclitaxel, actinomycin, mitomycin, etoposide, tenoposide, vincristine, vinblastine, colchicine, gelonin, and calicheamicin.
14. The method of claim 11 , wherein the toxin is selected from the group consisting of diphtheria toxin, enomycin, phenomycin, Pseudomonas exotoxin (PE) A, PE40, abrin, abrin A chain, mitogellin, modeccin A chain, and alpha-sarcin.
