Michael Potente to strengthen vascular research at BIH, Charité and MDC

With the appointment of BIH Professor Michael Potente, the Berlin Institute of Health (BIH), Charité – Universitätsmedizin Berlin and the Max Delbrück Center in the Helmholtz Association (MDC) are strengthening their joint focus area “Translational Vascular Biomedicine.” Potente, a trained cardiologist, is particularly interested in the innermost cell layer that lines our blood vessels, the endothelium. He has visited Berlin regularly since 2017 as a BIH Visiting Professor, funded by Stiftung Charité. The 43-year-old currently works at the Max Planck Institute for Heart and Lung Research in Bad Nauheim, and in the future will conduct research at the BIH and MDC’s Käthe Beutler Building on the Berlin-Buch campus.

“Cardiovascular diseases are still one of the most frequent causes of illness and death,” says Prof. Axel Radlach Pries, Dean of Charité and interim Chairman of the BIH Executive Board. “Since changes in vascular function are a factor in many diseases, the BIH decided some time ago to establish a Translational Vascular Biomedicine focus area in order to achieve significant progress and translational success in this field. We are delighted to be able to complement and expand upon this research in such an outstanding way with the appointment of Michael Potente.”

Understanding the growth and function of blood vessels

Michael Potente is mainly interested in the influence of metabolism on blood vessels. “We want to understand how metabolic processes control the growth, remodeling and function of blood vessels,” explains Potente, who currently heads the Angiogenesis and Metabolism Laboratory at the Max Planck Institute for Heart and Lung Research in Bad Nauheim. For example, a lack of oxygen and nutrients can lead to the formation of new blood vessels (a process known as angiogenesis) in tumors. Angiogenesis also plays a central role in eye diseases like wet macular degeneration, which leads to blindness if left untreated. “In this case, therapeutic interventions are already possible thanks to the use of inhibitors that suppress the abnormal growth of the blood vessels,” reports Potente.

However, in other diseases, such as chronic ischemic heart disease or peripheral artery disease in the legs, blocked blood vessels still cause a lack of oxygen and nutrients to reach the tissue, but unfortunately this often does not lead to the sufficient formation of new blood vessels. “We would hope for new, functional vessels to grow that would restore the supply – but here, the underlying disease prevents that from happening,” explains Potente. “If it were possible to specifically promote the growth of new blood vessels, this would have great therapeutic value.” Unfortunately, previous attempts to do so have not achieved long-term success, and have instead resulted in side effects.

Differing endothelia in different organs

Potente and his colleagues therefore hope to understand how the organ-specific environment affects blood vessels – particularly the endothelium. In order to discover the molecular and cellular mechanisms behind these differences, Potente was awarded a €2 million ERC Consolidator Grant from the European Research Council in 2017. It was also at this time that he came to Berlin regularly as a BIH Visiting Professor. The Stiftung Charité has promoted this collaboration, which has been fundamental for the appointment, in the course of tis Private Ecellence Initiative Johanna Quandt. He was invited by BIH Professor Holger Gerhardt, who heads the Integrative Vascular Biology Lab at the MDC and is also spokesperson for the Translational Vascular Biomedicine focus area at the BIH. “I know very few scientists like Michael Potente who carry out innovative research at the highest level with such enthusiasm, curiosity, and a keen sense of the most important issues,” says Gerhardt. “His work is constantly uncovering new connections and has a lasting impact on our understanding of the fascinating biology of blood vessels. I am hugely looking forward to working with him to further advance the translation of these findings into clinical practice.”

The aesthetics of blood vessels

As a cardiology specialist, Michael Potente is also active on the clinical side. In Berlin, he hopes to contribute his experience working at the interface between basic research and patient care – and thus strengthen the focus on translational vascular biomedicine. “I am fascinated by the aesthetics of blood vessels, the advancement of scientific knowledge and, ultimately, the possibility of one day making basic research applicable in the diagnosis and treatment of disease.” This is a sentiment fully in line with the BIH’s mission of turning research into health.

Michael Potente was born in Aachen in 1976 and studied medicine at Goethe University Frankfurt and the University of Toronto. Already in the course of his experimental doctoral thesis at Goethe University Frankfurt, which he completed in 2003, he conducted research into blood vessels. He then worked both as a postdoctoral research at the Institute of Cardiovascular Regeneration and as a physician in the Department of Cardiology of Goethe University Frankfurt, where he qualified as a professor in the field of internal medicine in 2013. In 2012 he established his own research group at the Max Planck Institute for Heart and Lung Research in Bad Nauheim. Potente has already received numerous awards and grants, including an ERC Starting Grant, an ERC Consolidator Grant and the distinction as a European Molecular Biology Organization (EMBO) Young Investigator. He has published his research in distinguished journals and serves as an expert reviewer for numerous international scientific journals.
