20100145441 | THERAPEUTIC AGENTS FOR ANGIOGENESIS-RELATED DISEASES COMPRISING CHONDROMODULIN-I AS ACTIVE INGREDIENT - An objective of the present invention is to analyze the function of anti-angiogenic factors in cardiac valves or such to elucidate the developmental mechanism of angiogenesis-induced diseases.

The present inventors discovered that chondromodulin-I was markedly expressed in cardiac valves, and plays an important role in maintaining normal functions of the valves by preventing angiogenesis, thickening, and calcification which lead to valvular heart diseases. Chondromodulin-I proteins and substances that activate the expression or function of the proteins are expected to have therapeutic effects against angiogenesis-induced diseases. | 06-10-2010 |
