Newswise — PHILADELPHIA – Ronen Marmorstein, PhD, a professor of Biochemistry and Biophysics in the Perelman School of Medicine at the University of Pennsylvania, is one of five investigators who received a grant from the Arnold and Mabel Beckman Foundation for the creation of a state-of-the-art cryogenic electron microscopy (cryo-EM) facility. The investment supports research in chemistry and the life sciences and will also go towards maintaining the cryo-EM facilities and hiring of new faculty skilled in its uses.
Four research universities along with Penn -- Johns Hopkins University School of Medicine, Massachusetts Institute of Technology, the University of Utah, and the University of Washington School of Medicine – received a total of $12.5 million from the Foundation. These institutions were selected based on their potential to accelerate fundamental research and discovery already underway.
“This is high-end instrumentation that can be used to determine the atomic structure of complex protein units as they exist in their natural cellular environment,” Marmorstein said. “The technology lets us basically deep freeze biological samples while at the same time irradiating them with high-intensity electrons to image the three-dimensional shape in atomic detail.”
The field of structural biology has been transformed with the development of cryo-EM to determine atomic structures that are currently beyond the reach of more traditional techniques such as X-ray crystallography and nuclear magnetic resonance, which have significant limitations on sample preparation requirements.
“The new cryo-EM capabilities will enable fundamental advances in our understanding of biological processes and will also contribute to the structure-based development of new therapeutics,” Marmorstein said. Developing potent new compounds often involves structure-based tweaking to optimize the molecule destined to be a drug. In cases where such compounds bind to much larger complexes made of many proteins, cryo-EM may be the only way to accurately view the binding sites to develop drugs.
“While the expense can make acquiring this technology via federal grants prohibitive, we as a private foundation are in a unique position to support major infrastructure investments to enable broader use of this new tool and increase access for young scientists to this exciting field of study,” said Anne Hultgren, executive director of the Beckman Foundation.
Penn Medicine is one of the world's leading academic medical centers, dedicated to the related missions of medical education, biomedical research, and excellence in patient care. Penn Medicine consists of the Raymond and Ruth Perelman School of Medicine at the University of Pennsylvania (founded in 1765 as the nation's first medical school) and the University of Pennsylvania Health System, which together form a $6.7 billion enterprise.
The Perelman School of Medicine has been ranked among the top five medical schools in the United States for the past 20 years, according to U.S. News & World Report's survey of research-oriented medical schools. The School is consistently among the nation's top recipients of funding from the National Institutes of Health, with $392 million awarded in the 2016 fiscal year.
The University of Pennsylvania Health System's patient care facilities include: The Hospital of the University of Pennsylvania and Penn Presbyterian Medical Center -- which are recognized as one of the nation's top "Honor Roll" hospitals by U.S. News & World Report -- Chester County Hospital; Lancaster General Health; Penn Wissahickon Hospice; and Pennsylvania Hospital -- the nation's first hospital, founded in 1751. Additional affiliated inpatient care facilities and services throughout the Philadelphia region include Good Shepherd Penn Partners, a partnership between Good Shepherd Rehabilitation Network and Penn Medicine.
Penn Medicine is committed to improving lives and health through a variety of community-based programs and activities. In fiscal year 2016, Penn Medicine provided $393 million to benefit our community.
