20080311120 | AUTOCRINE GROWTH FACTOR RECEPTOR ANTIBODIES AND METHODS - Disclosed herein are antitumor compositions and methods of interfering with the biological activity of PC cell derived growth factor (PCDGF), anti-PCDGF receptor antibodies, fragments thereof, and methods of making anti-PCDGF receptor antibodies. The methods involve inhibiting the proliferation of tumor cells expressing the PCDGF receptor by contacting the surface of the cell with anti-PCDGF receptor antibodies. Anti-PCDGF receptor antibodies are capable of binding to the surface of a cell and interfering with the binding of PCDGF to its receptor. Also provided are compositions comprising anti-PCDGF receptor antibodies and cytotoxic molecules (e.g., toxins, oncotoxins, mitotoxins, immunotoxins, and antisense oligonucleotides). | 12-18-2008 |
20090010931 | COMPOSITIONS AND METHODS FOR RESTORING SENSITIVITY TO TREATMENT WITH HER2 ANTAGONISTS - Methods and compositions for restoring growth inhibition sensitivity to a tumor cell resistant to growth inhibition by HER2 antagonists. The methods involve administering a PCDGF antagonist to the cell in an amount effective to stimulate or restore growth inhibition sensitivity to HER2 antagonists. The invention also provides treatment regimens, and therapeutic compositions comprising an HER2 antagonist and a PCDGF antagonist. | 01-08-2009 |
20090203047 | 88kDa tumorigenic growth factor and antagonists - This invention relates to products and methods for treating cancer and for diagnosing tumorigenicity and other diseases associated with alteration in GP88 expression or action. Antagonists to an 88 KDa autocrine growth and tumorigenicity stimulator are provided which inhibit its expression or biological activity. The antagonists include antisense oligonucleotides and antibodies. | 08-13-2009 |
20100021475 | METHODS AND COMPOSITIONS FOR INHIBITING THE GROWTH OF HEMATOPOIETIC MALIGNANT CELLS - Disclosed herein are compositions and methods for reducing the growth of hematopoietic malignant cells (e.g., B-cell leukemia cells). The methods involve reducing the growth of hematopoietic malignant cells by contacting hematopoietic malignant cells with GP88 antagonists. GP88 is an 88 KDa autocrine growth factor that promotes the growth of hematopoietic malignant cells. Antagonists to GP88 are provided which inhibit its expression or biological activity. The antagonists include antisense oligonucleotides and antibodies. Also provided are methods for determining if a patient is responding or is responsive to anti-cancer therapy (e.g., glucocorticoid therapy). Increased levels of GP88 in hematopoietic cells indicates a patient is not responding or responsive to anti-cancer therapy. | 01-28-2010 |
20100111928 | Methods and kits for diagnosis tumorgenicity - Methods and kits for diagnosing tumorigenicity by measuring the concentration of GP88 in blood, plasma, serum, saliva, urine and other biological fluids. The methods and kits detect GP88 in biological fluids at a concentration as low as about 0.1 to 10 nanograms per milliliter and are useful for determining whether a patient has a tumorigenic condition, whether the patient is likely to be responsive to anti-tumorigenic therapies, and whether the treated patient is responding to anti-tumorigenic therapy by measuring the concentration of GP88 in the patient's serum or other biological fluid. | 05-06-2010 |
20110053182 | DIAGNOSIS OF PRE-CANCEROUS CONDITIONS USING PCDGF AGENTS - The present invention relates to methods and compositions designed for the treatment or management of pre-cancerous conditions, especially in order to prevent, delay, or decrease the likelihood that the pre-cancerous condition will progress to malignant cancer. The methods of the invention comprise the administration of an effective amount of one or more agents that decrease/inhibit PCDGF expression, secretion, and/or activity. The invention also provides pharmaceutical compositions comprising one or more PCDGF agents. In some embodiments, the PCDGF agents can be administered with other therapeutic agents for treatment or management of a pre-cancerous condition that are not PCDGF-based. Diagnostic methods and methods for screening for therapeutically useful PCDGF agents are also provided. | 03-03-2011 |
20120087918 | METHODS AND COMPOSITIONS FOR INHIBITING THE GROWTH OF HEMATOPOIETIC MALIGNANT CELLS - Disclosed herein are compositions and methods for reducing the growth of hematopoietic malignant cells (e.g., B-cell leukemia cells). The methods involve reducing the growth of hematopoietic malignant cells by contacting hematopoietic malignant cells with GP88 antagonists. GP88 is an 88 KDa autocrine growth factor that promotes the growth of hematopoietic malignant cells. Antagonists to GP88 are provided which inhibit its expression or biological activity. The antagonists include antisense oligonucleotides and antibodies. Also provided are methods for determining if a patient is responding or is responsive to anti-cancer therapy (e.g., glucocorticoid therapy). Increased levels of GP88 in hematopoietic cells indicates a patient is not responding or responsive to anti-cancer therapy. | 04-12-2012 |
