Charakterisierung von BMPER in der Blutgefässentwicklung und bei vaskuären Erkrankungen
Final Report Abstract
The project "Role of BMPER in vascular health and disease" elucidated the regulation and expression of BMPER in cardiovascular diseases. We were able to position the novel protein BMPER within known signaling cascades and demonstrated that BMPER holds a key role in important diseases such as vascular inflammation. Taken the data together, the novel protein BMPER was identified as a protective player in vascular inflammation. Loss of BMPER results in a pro-inflammative state whereas excess BMPER reduces vascular inflammation. We have extended these insights to lung epithelium and found that similar principles hold true. BMPER has a protective role, where as loss of BMPER increases cell damage. As frequently in biologic processes BMPER expression may also be double-edged sword which is demonstrated by our lung tumor experiments. In lung tumors loss of BMPER comes along with reduced tumor cell growth. These findings underline that a detailed understanding of BMPER expression and regulation is necessary to keep a fine-tuned equilibrium between risk and benefit. In the present project we have contributed to this understanding laying the ground for future experiments to further investigate this very promising vascular mediator.
