Discovering Cell Identity: $6 Million NIH Grant Funds New Penn Medicine Research to Uncover Cardiac Cell Development

Congratulations to Raj Jain, MD, on this fantastic award! Please read the full news release below or at Penn Medicine News. To learn more about Dr. Jain’s work, please visit his Lab Website.


Historically, scientists have studied how cells develop and give rise to specialized cells, such as heart, liver, or skin cells, by examining specific proteins. However, it remains unclear how many of these proteins influence the activity of hundreds of genes at the same time to turn one cell type into another cell type. For example, as the heart develops, stem cells and other specialized cells will give rise to heart muscle cells, endothelial cells (lining of blood vessels), smooth muscle cells, and cardiac fibroblasts. But the details of this process remain mysterious.

As a result of a $6 million, seven-year grant from the National Heart, Lung, and Blood Institute of the National Institutes of Health (NIH), researchers from the Perelman School of Medicine at the University of Pennsylvania are launching new efforts to uncover how the development and maintenance of heart cells is influenced by DNA. These insights could help drive future research on new therapies for cardiac disease.

Penn Medicine researchers propose that nuclear architecture, which governs the availability of hundreds of genes within a cell, plays a critical role in achieving the proper identity of a cell. Specifically, they plan to study how the packaging and organization of DNA in 3D—meaning understanding how DNA folds and twists in a complex way to fit into the tiny space of a cell nucleus—impacts cell development. The work is supported by their previous research, which shows that nuclear architecture governs cardiac cellular identity during both development and disease.

“This research has the potential to significantly advance our understanding of how cardiac cells arise and keep their identity for a lifetime,” said Principal Investigator Rajan Jain, MD, an assistant professor of  Medicine and Cell and Developmental Biology in the Perelman School of Medicine at the University of Pennsylvania. “By viewing congenital heart disease and other cardiac diseases through the lens of how DNA is organized in the cell, many therapeutic opportunities that have remained untapped may come to light.”

The way the nucleus is organized inside cells plays a crucial role in controlling the genes that determine cell identity. The nucleus acts like the command center of the cell, controlling what genes are accessible or available for use.

The Jain lab’s work suggests that the way the DNA is folded and arranged within the nucleus can determine which genes are accessible and active, influencing the cell’s identity. The way the DNA is folded and organized can be compared to a complex origami structure, where each fold and crease determines the final shape and function. The research aims to unravel the role of genome folding in controlling cell behavior, particularly in heart cells, and to identify key processes involved in this regulation. Researchers will also explore how the spatial positioning of DNA affects gene activity during the development of heart cells. By studying this process, researchers can examine how the identity of heart cells is maintained. This process is important for our overall health; incorrect development of heart cells or altering its identity could contribute to congenital heart disease or cardiomyopathy.

“As I trained it was always assumed that therapies can’t target specific proteins in the nucleus, but that has changed over the last few years,” Jain said. “Leveraging those advancements and past work as an inspiration, I hope this research will eventually allow us to design new medicines that will directly target how DNA is organized.”

This research is supported by the National Heart, Lung, and Blood Institute of the NIH (R35HL166663).

Kathryn E. Wellen, Ph.D. selected for AACR Award for Outstanding Achievement in Basic Cancer Research

Congratulations to Core Member Kathryn E. Wellen, Ph.D. on being selected for the American Association for Cancer Research Award for Outstanding Achievement in Basic Cancer Research!

This award honors an early-career investigator for meritorious achievements in basic cancer research. A member of the ACC Cancer Therapeutics Research Program, Dr. Wellen is recognized for her research establishing new paradigms in the understanding of cancer cell metabolism. The chemical reactions that change food into energy function very differently in cancer cells compared to healthy cells, and these metabolic processes are a driving force behind cancer growth. Dr. Wellen’s work has shed light on how cancer cell metabolism works at a molecular level, and shown how cellular metabolism is connected to gene regulation. Many of her discoveries have opened new fields of study involving the mechanisms of crosstalk between metabolic pathways, signaling networks, and the epigenome. Building on recent findings, Dr. Wellen’s lab is also investigating how diet and nutrition play impact tumor growth.

Penn Epigenetics Institute Tribute to C. David Allis

C. David Allis
C. David Allis (1951 – 2023)

Dear Epigenetics Institute,

We were all deeply saddened to learn of David Allis’ passing in early January, at far too young an age of 71.  David’s discoveries over nearly 30 years, launching with his groundbreaking 1996 Cell paper reporting the first nuclear histone acetyltransferase, GCN5, had enormous impacts on the fields of histone biology and epigenetics. His ideas and vision extended well beyond these fields, to broadly influence and propel research of nuclear processes in the context of chromatin.  David was elected to scientific academies in the United States, and won numerous prestigious awards, including the Japan Prize, the Life Sciences Breakthrough Prize, and the Albert Lasker Basic Medical Research Award.

I feel personal sadness as my lab group and I were very fortunate to have collaborated with David, and worked in parallel, in the early revelatory years of histone modifications.  I was always amazed by his passion and wide-eyed excitement for new findings that, over the years, led to an ever-expanding reach of histone biology into every aspect of chromatin-based processes.  The field and science as a whole have indeed lost a tremendous spokesman, as his lectures and conference talks were truly inspirational and, without a doubt, recruited many graduate students, postdocs, and medical fellows into the world of epigenetics.

David was an exceptional and universally admired scientist, but he was also an amazing mentor, as is clear from the testimonials below from his postdoctoral trainees Erica Korb, Richard Phillips and Liling Wan, now all, to our great delight, core faculty members of the Epigenetics Institute.

With deep sadness on this occasion,

Shelley Berger, PhD

Erica Korb, PhD

Dave was an incredible scientist, a wonderful mentor, and an incredibly kind and caring person. We’re all devastated by this loss and Dave will be missed by the many, many of us who passed through his lab and were lucky enough to know him and learn from him. One of the things that made him the happiest was seeing his lab members go off to start new labs and train a new generation of scientists. He was particularly thrilled that several of us had the opportunity to come to the Epigenetics Institute to pursue our science. He knew what an amazing place this was and how lucky we were to carry his training to such an incredible environment. Dave was also unfailingly humble and never stopped appreciating the beauty of a simple but elegant experiment. Even in the age of next generation sequencing, Dave’s favorite results were usually in the form of a simple western blot of histone modification. He taught us all that powerful science can come in many forms and we will remember him every time we see a particularly beautiful western blot of histone modifications, that helps to remind us of his favorite saying, ‘Every amino acid matters.’ While we miss him very much, it’s comforting to know that by carrying on his science and training others, we are honoring his memory every day.

Richard Phillips, PhD

Dave was a brilliant scientist. His contributions as a pioneer in chromatin biology are having wide reaching implications in biomedical science and medicine, yet they were borne out of a pure love for discovery and biochemistry which we as trainees witnessed on a regular basis. Dave was one of the most humble individuals you might encounter. Very open minded to new ideas yet deeply rigorous and incisive in his analysis. A unique talent in simplifying complex ideas and making them accessible for other scientists.  But perhaps his most special quality was the care and enthusiasm he had for people. As his mentee you knew he cared about how you were doing outside of the lab. He would cherish news about personal milestones and he loved to decorate his lab with photos lab members shared with him, just one of the many things he did to create a ‘family’ environment. Dave supported, promoted and advised us all so enthusiastically in our scientific careers and he was so excited for his trainees to come to the Epigenetics institute and continue our work in this environment. I will miss Dave sorely but I feel privileged to have been able to learn from such a great man.

Liling Wan, PhD

With the passing of David Allis, the scientific community has lost one of its most inspirational leaders and brilliant minds. Besides his enormous impact on biomedical science and discovery, Dave had influenced many scientists inside (including Erica, Richard, and myself at the Epigenetics Institute) and outside his laboratory through his enthusiasm, kindness, generosity, and support. I have not seen anyone who loved science more than Dave. His genuine interest in science and other people’s work, coupled with his rare gift of simplifying complex ideas and making them accessible to non-experts, inspired and attracted many trainees and collaborators over the years to study chromatin and its role in diverse biological processes. Working in Dave’s lab was a delightful and rewarding experience. He mentored us with relentless positivity and encouragement. He always promoted our careers whenever possible during our training in his lab and continued to do so after we launched our independent careers. His care of people went beyond work. He celebrated trainee’s personal milestones with equal if not more joy as he did for scientific accomplishments. Like many of us in the extended Allis family, I am forever grateful for his mentorship and friendship and aspire to follow his footsteps to bring a positive impact on science and people. His legacy will live on.
