Abstract: A means for following the growth of experimental neoplasms involves administering recombinant tumor cells containing an expression construct encoding a secretable marker to an experimental animal and measuring secreted marker in the urine of animals bearing tumors formed by such recombinant tumor cells. Urinary marker levels are quantitatively related to tumor loads. Urinary marker can be detected before tumors are grossly visible or clinically apparent. Marker levels decrease following surgical excision or chemotherapeutic treatment, with an estimated half-life of 11 hours. This approach is applicable to the study of many experimental tumor systems.

Abstract: Rhomboid Related Proteins (RRPs), involved in the EGFR signaling pathway, are provided. Transgenic, nonhuman mammals containing a transgene encoding an RRP polypeptide or a gene effecting the expression of an RRP polypeptide, along with methods of modulating the interaction of RRP proteins with their pathway members, and methods of screening for agents that modulate the interaction of an RRP polypeptide with an RRP binding target, such as RRP-specific antibodies and small molecules identified in high throughput screens, are also provided. Modulating agents identified using the methods of the invention can be used to specifically inhibit growth of tumor cells that overexpress an RRP protein.

Abstract: Compounds inhibiting the activation of the nuclear factor ?B (NF-?B) are used for the preparation of medications adapted for the treatment of malignant hemopathies and solid tumors, and for the prevention of the appearance or the treatment, of phenomena of resistance to cytotoxic molecules used in the scope of treatment of the above pathologies, appearing in patients treated with these molecules when the latter are adapted to activate NF-?B.

Abstract: The isolation and characterization of cDNAs encoding poly(ADP-ribose) glycohydrolase (PARG) enzymes and the amino acid sequences of PARGs from several species are described. PARG is involved in the cellular response to DNA damage and its proper function is associated with the body's response to neoplastic disorder inducing agents and oxidative stress. Expression vectors containing the cDNAs and cells transformed with the vectors are described. Probes and primers that hybridize with the cDNAs are described. Expression of the cDNA in E. coli results in an enzymatically active protein of about 111 kDa and an active fragment of about 59 kDa. Methods for inhibiting PARG expression or overexpressing PARG in a subject for therapeutic benefit are described. Exemplary of PARG inhibitors are anti-sense oligonucleotides. The invention has implications for treatment of neoplastic disorder, heart attack, stroke, and neurodegenerative diseases. Methods for detecting a mutant PARG allele are also described.

Abstract: The invention provides methods and compositions relating to Kuz involvement in angiogenesis.

Abstract: The invention relates to an anti-cancer agent containing ?-chain protein (?-fragment) of HGF (hepatocyte growth factor) as an active ingredient. The active ingredient of ?-fragment has a specific suppressing effect on invasion and metastasis of cancer cells such as gallbladder cancer, lung cancer and other, which are highly metastatic and result in a high mortality. Therefore, the agent of the invention is used in treatment and prevention of cancer as an anti-cancer agent, and is extremely useful clinically.

Abstract: The invention provides antineoplastic composition containing an inhibitor of angiogenesis and an inhibitor of DNA topoisomerase type I enzyme activity.

Abstract: A three-dimensional in vitro culture system comprising breast epithelial cells, endothelial cells and breast fibroblasts supports growth and functional differentiation of preneoplastic breast epithelial cells and endothelial cells and recapitulates estrogen induced in vivo effects on angiogenesis and proliferative potential of breast epithelial tissue. This model permits the generation of functional vascular networks and local proliferative ductal alveolar outgrowths with invasive potential. Both these processes are augmented by estrogen. This culture model is used to evaluate agents for their effects, whether stimulatory or inhibitory, on preneoplastic breast disease and its progression to cancer.

Abstract: The present invention provides the TWEAK receptor and methods for identifying and using agonists and antagonists of the TWEAK receptor. In particular, the invention provides methods of screening for agonists and antagonists and for treating diseases or conditions mediated by angiogenesis, such as solid tumors and vascular deficiencies of cardiac or peripheral tissue.

Abstract: Angiogenesis is a highly regulated process, yet many diseases are driven by unregulated angiogenesis. For example, the growth and metastasis of tumors is dependent on the growth of new blood vessels, which nurture the tumor by providing not only a growth-conducive environment but also a route by which metastatic cells can escape. The present invention provides an angiogenesis inhibiting agent endorepellin, its fragments or derivatives, or analogs thereof, which inhibit angiogenesis. The invention disclosed herein provides a novel therapeutic approach to the treatment of tumors, and other angiogenesis-mediated diseases or conditions, by inhibiting the generation of new blood vessels. The present invention also provides anti-endorepellin, its fragments or derivatives, or analogs thereof, antibodies for the detection, diagnosis and monitoring of angiogenesis-mediated diseases or conditions.

Abstract: The present invention relates to a novel hybridoma cell line which secretes monoclonal antibodies capable of binding to the AT1 subtype of the Angiotensin II receptor. It also relates to monoclonal antibodies secreted by the hybridoma, which antibodies may be used in diagnostic test kits as well as having therapeutic applications.

Abstract: The invention relates to newly identified cancer associated antigens. It has been discovered that each of these molecules provokes antibodies when expressed by a subject. The ramifications of this observation are also a part of this invention.

Abstract: There is provided a composition having an effective amount of N-terminally truncated galectin-3 in a pharmaceutically acceptable carrier. Also provided by the present invention is a method of treating cancer by administering to a patient in need of such treatment an effective amount of N-terminally truncated galectin-3 in a pharmaceutically acceptable carrier.

Abstract: The present invention is directed to the use of antibodies or binding portions thereof, probes, ligands, or other biological agents which either recognize an extracellular domain of prostate specific membrane antigen or bind to and are internalized with prostate specific membrane antigen. These biological agents can be labeled and used for detection of cancerous tissues, particularly cancerous tissues proximate to or containing vascular endothelial cells, which express an extracellular domain of prostate specific membrane antigen. The labeled biological agents can also be used to detect normal, benign hyperplastic, and cancerous prostate epithelial cells or portions thereof. They also can be used alone or bound to a substance effective to ablate or kill such cells as a therapy for prostate or other cancers.

Abstract: There is disclosed a cancer malignancy diagnostic assay comprising obtaining a sample of a body fluid or tissue, performing a sequence identity assay to look for the presence of iPFK-2 specific sequences; an anticancer pharmaceutical composition comprising a specific antisense oligonucleotide to the inventive isolated iPFK-2 sequence and a pharmaceutically acceptable oligonucleotide carrier; and a method for finding therapeutically active anti-cancer compounds comprising screening compounds for activity to inhibit iPFK-2, preferably kinase activity.
