Patent number: 5994131Abstract: Disclosed is a method of screening candidate compounds for the ability to modulate the level of morphogenic protein in mammalian system. The method includes determining a parameter indicative of the level of production of a morphogenic in a cell culture known to produce the morphogen, incubating a candidate compound with the culture for a time sufficient to allow the compound to affect the production of the morphogenic protein, and then assaying the culture again to detect a change in the level of morphogenic protein production.Type: GrantFiled: August 15, 1997Date of Patent: November 30, 1999Assignee: Creative BioMolecules, Inc.Inventors: John E. Smart, Hermann Oppermann, Engin Ozkaynak, Thangavel Kuberasampath, David C. Rueger, Roy H. L. Pang, Charles M. Cohen

Patent number: 5707810Abstract: In one aspect, the present invention provides a method of diagnosing renal tissue damage or disease by measuring endogenous expression of OP-1 by renal tissue of a mammal (e.g., a human) in which a depression of endogenous expression relative to undamaged or undiseased mammalian renal tissue indicates a diagnosis that the mammal is afflicted with renal tissue damage or disease. Also disclosed are methods of diagnosing renal tissue damage or disease in a mammal. The methods involve detecting and/or measuring the expression of the OP-1 (BMP-7) gene or protein in the mammal. Depression of OP-1 expression may be used to diagnose renal tissue damage or disease.Type: GrantFiled: May 6, 1996Date of Patent: January 13, 1998Assignee: Creative BioMolecules, Inc.Inventors: John E.
