PHILADELPHIA – Patrick Seale, PhD, assistant professor of Cell and Developmental Biology at the School of Medicine and Ritesh Agarwal, PhD, assistant professor in the School of Engineering and Applied Science, have received the New Innovator Award from the National Institutes of Health (NIH), providing $1.5 million to each over five years to support their research.

The awards are given by the NIH to address two important goals: stimulate highly innovative research that has the potential for significant impact and support promising early stage investigators who propose bold new approaches that have the potential to produce a major impact on a broad area of biomedical or behavioral research.

Seale’s project, “Molecular Regulation of Brown Adipose Cell Fate in Somitic Stem Cells,” addresses obesity and being overweight, a major risk factor for a multitude of health problems, including: type 2 diabetes, heart disease, stroke, hypertension, and certain cancers.  Obesity is caused by a defect in energy balance when energy from food intake chronically exceeds energy expenditure. Brown fat tissue is highly adapted to expend chemical energy as heat and can therefore counteract obesity. Significant amounts of this tissue has been recently identified in adult humans raising the possibility that variations in brown fat function may influence propensity for weight gain. The goal of this project is to identify and study the precursor cells for brown fat in developing and adult tissues.   These studies will uncover mechanisms that control brown adipose cell fate and suggest new therapeutic targets for obesity and metabolic disease.

“This award provides us with a tremendous opportunity to make important new discoveries related to obesity and metabolic disease,” says Seale. “Because of this grant, we are able to explore new research avenues and incorporate high-risk, discovery-oriented experiments into our program.”

Agarwal’s project, “Optoelectronic Nanowire Probes for Investigation of Intracellular Processes,” seeks to assemble nanowire devices with optical and electrical functions to probe cell and intracellular dynamics with unprecedented resolution. By combining nanowire waveguides, fluorophores, quantum dots, lasers, light emitting diodes, and photodetectors, his team hopes to create a new generation of biological imaging: probes that can target subcellular regions, measuring for the first time, in real time, chemical reactions, cellular signaling and cellular reactions due to complex phenomena like a locally delivered drug.

“The ability to visualize in vitro intra- and inter- cellular processes in real time will aid the design of new drugs for a large number of diseases that impact public health,” says Agarwal.

"NIH is pleased to be supporting early-stage investigators from across the country who are taking considered risks in a wide range of areas in order to accelerate research," said Francis S. Collins, M.D., Ph.D., director of the National Institutes of Health. “We look forward to the results of their work."

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 $4.3 billion enterprise.

The Perelman School of Medicine has been ranked among the top five medical schools in the United States for the past 17 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 2013 fiscal year.

The University of Pennsylvania Health System's patient care facilities include: The Hospital of the University of Pennsylvania -- recognized as one of the nation's top "Honor Roll" hospitals by U.S. News & World Report; Penn Presbyterian Medical Center; Chester County Hospital; 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 Chestnut Hill Hospital and 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 2013, Penn Medicine provided $814 million to benefit our community.
