The invention provides methods for detecting abnormal prostate conditions, such as benign prostatic hyperplasia (BPH), prostatic intraepithelial neoplasia (PIN), and adenocarcinoma, in an animal by comparing the amount of the Breast Tumor Kinase (BRK) tyrosine kinase in the nuclei of prostate luminal epithelial cells in a test sample with an amount of nuclear BRK protein in epithelial cells of normal prostate glands.

Altered intracellular localization of BRK/Sik protein tyrosine kinase in human prostate tumors

AnnexinA2 (ANXA2), a member of the Annexin family of calcium-dependent, phospholipid binding proteins, is one of a panel of identified antigens recognized by the post-vaccination sera of patients who demonstrated prolonged disease-free survival following multiple vaccinations. AnnexinA2 is abundantly expressed in pancreatic adenocarcinomas and cell surface/membrane AnnexinA2 increases with the progression from premalignant lesions to invasive pancreatic adenocarcinomas. The cytoplasmic to cell surface translocation of AnnexinA2 expression is critical for pancreatic cancer cell invasion. In addition, phosphorylation of AnnexinA2 at Tyrosine 23 is important for its localization to the cell surface and for the invasion of pancreatic cancer cells. Finally, loss of AnnexinA2 leads to the loss of the Epithelial-Mesenchymal Transition.

A human endogenous retrovirus-related Mv-75,000 protein, containing the decapeptide sequence Glutamic Acid-Asparagine-Proline-Serine-Glutamine-Phenylalanine-Tyrosine-Glutamic Acid-Arginine-Leucine, a synthetic undecapeptide Sp-23 based on the decapeptide, and specific polycolonal and monoclonal antibodies and specific nucleic acid probes are used as specific reagents for the detection and treatment of tumors such as renal cell adenocarcinoma and choriocarcinoma, among others, and placental disorders including blighted ova, hydatiform and destructive moles.

Human retrovirus-related products and methods of diagnosing and treating conditions associated with said retrovirus

In order to identify a gene that can serve as an indicator for predicting the effectiveness of a drug treatment of cancer and to provide a novel method for predicting the effectiveness of a drug treatment targeting said gene, lung adenocarcinomas were subjected to whole-transcriptome sequencing. As a result, in-frame fusion transcripts between the KIF5B gene and the RET gene were identified. The KIF5B-RET gene fusions were detected in 6 out of 319 (2%) LADC specimens from Japanese individuals and 1 out of 80 (1%) LADC specimens from U.S.A. individuals. None of the seven subjects revealed known activating mutations such as EGFR, KRAS or ALK oncogenes; thus, said gene fusions were found to be responsible mutations (driver mutations) for oncogenesis. Since said gene fusions are considered to induce constitutive activation of RET tyrosine kinase protein, it was found that treatments with RET tyrosine kinase inhibitors are effective in patients with detection of said gene fusions.
