Transmembrane serine protease overexpressed in ovarian carcinoma and uses thereof
View Patent ↗The present invention provides a TADG-12 protein and a DNA fragment encoding such protein. Also provided is a vector/host cell capable of expressing the DNA. The present invention further provides various methods of early detection of associated ovarian and other malignancies, and of interactive therapies for cancer treatment utilizing the DNA and/or protein disclosed herein.
1. A method for diagnosing cancer in an individual comprising the steps of:
(a) obtaining a biological sample from said individual;
(b) detecting a TADG-12 protein in said sample, wherein a TADG-12 protein is selected from the group consisting of SEQ ID NO:2, SEQ ID NO:4 and SEQ ID NO:8, and wherein the presence of said TADG-12 protein in said sample is indicative of the presence of a cancer in said individual, and wherein the absence of said TADG-12 protein in said sample is indicative of the absence of a cancer in said individual.
2. The method of claim 1 , wherein said biological sample is selected from the group consisting of blood, urine, saliva, tears, interstitial fluid, ascites fluid, tumor tissue biopsy and circulating tumor cells.
3. The method of claim 1 , wherein said detection of a TADG-12 protein is by means selected from the group consisting of Western blot, dot blot, ELIZA sandwich assay, radioimmunoassay and flow cytometry.
4. The method of claim 1 , wherein said cancer is selected from the group consisting of ovarian caner, breast cancer, lung cancer, colon caner, prostate cancer and other cancers in which TADG-12 is overexpressed.
5. A method for detecting malignant hyperplasia in a biological sample, comprising the steps of:
(a) isolating protein from said sample;
(b) detecting a TADG-12 protein in said sample, wherein a TADG-12 protein is selected from the group consisting of SEQ ID NO:2, SEQ ID NO:4 and SEQ ID NO:8, and wherein the presence of said TADG-12 protein in said sample is indicative of the presence of malignant hyperplasia, and wherein the absence of said TADG-12 protein in said sample is indicative of the absence of malignant hyperplasia.
6. The method of claim 5 , wherein said detection is by immunoaffinity to an antibody, wherein said antibody is directed against a TADG-12 protein.
7. The method of claim 5 , wherein said biological sample is selected from the group consisting of blood, urine, saliva, tears, interstitial fluid, ascites fluid, tumor tissue biopsy and circulating tumor cells.
