Disclosed are a novel prostatic acid phosphatase and corresponding coding region derived from mouse. Also disclosed is a method of producing an immune response against an autologous polypeptide tumor antigen by immunizing a subject with a xenogeneic polypeptide antigen, either alone, as part of a viral antigen construct, or as part of a pulsed dendritic cell preparation.

Presented is a therapeutic method to treat prostate carcinomas in mammals comprising the administration of cellular PAcP protein. Also presented is a method to diagnose androgen-insensitive prostate carcinomas by determining the expression level of cellular PAcP in the prostate carcinomas, a decrease in expression being indicative of androgen-insensitivity. A promoter region that is specifically expressed in prostate tissue is presented, as is a xenograft animal model that mimics human prostate carcinomas in the expression of cellular PAcP.

Disclosed are methods and compositions for monitoring, diagnosis, prognosis, and determination of treatment regimens in subjects suffering from or suspected of having a renal injury. In particular, disclosed are assays that detect one or more markers selected from the group consisting of Prostatic acid phosphatase, Lactotransfenin, Soluble erythropoietin receptor, Von Willebrand factor, Soluble endothelial protein C receptor, and Beta-2-glycoprotein 1 as diagnostic and prognostic biomarkers in renal injuries.

A DNA vaccine for the treatment of prostate cancer, comprising a plasmid vector comprising a nucleotide sequence encoding prostatic acid phosphatase (PAP) operably linked to a transcription regulatory element, wherein upon administration to a mammal a cytotoxic immune reaction against cells expressing PAP is induced. In preferred embodiment, the PAP encoded is a xenoantigen highly homologous to the autoantigen PAP of the mammal. Also disclosed are methods for inducing prostatitis, or inducing immune reaction to PAP, or treating prostate cancer in a mammal, using the DNA vaccine and pharmaceutical compositions comprising the vaccine. Preferably, xenoantigen vaccination is followed by boosting with autoantigen PAP from the same animal species as the mammal being treated.

The present invention relates to tumor associated antigen (TAA) peptides and to use of same, of polynucleotides encoding same and of cells presenting same as anti-tumor vaccines. More particularly, the present invention relates to tumor associated antigen peptides derived from Uroplakin Ia, Ib, II and III, Prostate specific antigen (PSA), Prostate acid phosphatase (PAP) and Prostate specific membrane antigen (PSMA), BA-46 (Lactadherin), Mucin (MUC-1), and Teratocarcinoma-derived growth factor (CRIPTO-1) and the use of same as anti-tumor vaccines to prevent or cure bladder, prostate, breast or other cancers, carcinomas in particular. Most particularly, the present invention relates to tumor associated antigen peptides which are presentable to the immune system by HLA-A2 molecules.

Provided are methods for the detection and diagnosis of acute coronary syndrome or ACS. The methods are based on the discovery that abnormal levels of selected analytes in sample fluid, typically blood samples, of patients who are at risk are supportive of a diagnosis of ACS. At least two new biomarkers for ACS are thus disclosed, MMP-3 and SGOT. Altogether the concentrations of twelve analytes provide a sensitive and selective picture of the patient's condition, namely, whether the patient is suffering a heart attack. Other important biomarkers for ACS are described, including but not limited to IL-18, Factor VII, ICAM-1, Creatine Kinase-MB, MCP-1, Myoglobin, C Reactive Protein, von Willebrand Factor, TIMP-1, Ferritin, Glutathione S-Transferase, Prostate Specific Antigen (free), IL-3, Tissue Factor, alpha-Fetoprotein, Prostatic Acid Phosphatase, Stem Cell Factor, MIP-1-beta, Carcinoembryonic Antigen, IL-13, TNF-alpha, IgE, Fatty Acid Binding Protein, ENA-78, IL-1-beta, Brain-Derived Nerotrophic Factor, Apolipoprotein A1, Serum Amyloid P, Growth Hormone, Beta-2 microglobulin, Lipoprotein (a), MMP-9, Thyroid Stimulating hormone, alpha-2 Macroglobulin, Complement 3, IL-7, Leptin, and IL-6. Kits containing reagents to assist in the analysis of fluid samples are also described.

The invention relates to the technical field of biology, in particular to a system and a method for expressing and purifying recombinant protein with 3'-nucleotidase as a tag and application of the recombinant protein. The system is characterized in by comprising a 3'-nucleotidase nucleotide sequence and a protein over-expression vector, a 3'-nucleotidase nucleotide sequence added with a protease recognition site, a protease nucleotide sequence matched with the protease recognition site, a lysis solution containing at least one of Li<+> and Ca<2+> ions, an eluent of a chelating agent containing at least one of Li<+> and Ca<2+> ions, and PAP (Prostatic Acid Phosphatase) agarose gel. The system disclosed by the invention is a simple, high-efficiency and economic system for purifying a target recombinant protein.

The purpose of the present invention is to provide a monoclonal antibody that is useful in specifically assaying tartrate resistant acid phosphatase 5b (TRACP-5b). A hybridoma producing a monoclonal antibody against TRACP-5b, said monoclonal antibody showing higher reactivity with TRACP-5b than with tartrate resistant acid phosphatase 5a (TRACP-5a) and, therefore, being specific to TRACP-5b, is obtained by cell fusion using, as an antigen, human recombinant TRACP-5b purified from silkworm silk gland. By using this monoclonal antibody, TRACP-5b in a specimen can be highly sensitively and specifically detected.

The present invention provides a novel phosphatidic acid phosphatase gene. The object of the present invention can be solved by providing a nucleic acid comprising the nucleotide sequence set forth in SEQ ID NO: 1, SEQ ID NO: 4, or SEQ ID NO: 5; a protein comprising the amino acid sequence set forth in SEQ ID NO: 2; and mutants thereof.

The present invention belongs to the field of biomedicine, and more particularly, the present invention provides a sequence of an anti-prostatic acid phosphatase (PAP) antibody and use thereof. The anti-PAP antibody disclosed in the present invention has higher levels of PAP or prostatic acid phosphatase-granulocyte-macrophage colony-stimulating factor fusion protein (Fusion Protein of Prostatic acid phosphatase-Granulocyte-macrophage colony-stimulating factor, PAP-GM-CSF). The affinity can be used for the purification of PAP or PAP-GM-CSF. At the same time, it can also be used for the diagnosis and treatment of prostate cancer.

The present invention provides phosphatidic acid phosphatase cDNAs and recombinant vectors comprising nucleic acids encoding proteins having phosphatidic acid phosphatase activity wherein 100 amino acids at the N-terminal region and DXDX(T / V) catalytic site motif are conserved in the protein.
