Abstract: Real-time microscopy of the dynamics of cells and tissues in 3D environments is opening new windows to understanding the biophysical mechanisms of complex biological processes. Direct visualization is allowing us to explore fundamental questions in more depth that include: How do cells migrate in 3D? How do cancer cells invade? How is the extracellular matrix assembled? How are organs formed? Visualizing how cells move and organize into tissues is not only providing descriptive insights, but is also leading to the identification of novel, unexpected physical and mechanical mechanisms relevant to tissue engineering. Cells can use varying combinations of cell adhesion to adjacent cells and to the surrounding extracellular matrix with localized cellular contractility to migrate, invade, and produce the complex tissue architecture needed for organ formation.

Kenneth Yamada Bio: Kenneth Yamada has been an NIH Distinguished Investigator since 2011. He received MD and PhD degrees from Stanford. He was a Section Chief at the National Cancer Institute for 10 years and has been a Section Chief at NIDCR since 1990. He is an elected Fellow of the AAAS and American Society for Cell Biology. His research focuses on discovering novel mechanisms and regulators of cell interactions with the extracellular matrix and their roles in embryonic development and cancer. His research group focuses on the mechanisms by which three-dimensional (3D) extracellular matrix mediates key biological events, including cell migration, tissue morphogenesis, and cancer cell invasion. His research places particular emphasis on characterizing the dynamic movements of cells and their extracellular matrix as tissues are remodeled in 3D in real time. The biological systems they study include human primary cells migrating in 3D, human tumor cells and tissues, and mouse organ development. He places particularly high priority on developing future independent research leaders.

Abstract: The most effective medicines are those that target the earliest causes of disease, rather than later manifestations. Engineering of biomolecules is a promising but underexplored approach to precisely detecting or targeting disease causes. I will present our work to develop a novel approach to treating cancer by detecting the signaling abnormalities that give rise to cancer. Interestingly, this effort involves biomolecular engineering at multiple scales: proteins, pathways, and viruses. I will also discuss how our work has translated serenditously to developing treatments for SARSCoV2.

“’Electronic Nose’ Accurately Sniffs Out Hard-to-Detect Cancers”

A.T. Charlie Johnson, Ph.D.

A.T. Charlie Johnson, Rebecca W. Bushnell Professor of Physics and Astronomy at the Penn School of Arts & Sciences, and member of the Penn Bioengineering Graduate Group has been working with a team of researchers on a new “electronic nose” that could help track the spread of COVID-19 based on the disease’s unique odor profile. Now, similar research shows that vapors emanating from blood samples can be tested to distinguish between benign and cancerous pancreatic and ovarian cells. Johnson presented the results at the annual American Society of Clinical Oncology meeting on June 4 (Abstract # 5544):

“It’s an early study but the results are very promising,” Johnson said. “The data shows we can identify these tumors at both advanced and the earliest stages, which is exciting. If developed appropriately for the clinical setting, this could potentially be a test that’s done on a standard blood draw that may be part of your annual physical.”

Penn, CHOP and Yale Researchers’ Molecular Simulations Uncover How Kinase Mutations Lead to Cancer Progression

by Evan Lerner

A computer model of a mutated anaplastic lymphoma kinase (ALK), a known oncogenic driver in pediatric neuroblastoma.

Kinases are a class of enzymes that are responsible for transferring the main chemical energy source used by the body’s cells. As such, they play important roles in diverse cellular processes, including signaling, differentiation, proliferation and metabolism. But since they are so ubiquitous, mutated versions of kinases are frequently found in cancers. Many cancer treatments involve targeting these mutant kinases with specific inhibitors.

Understanding the exact genetic mutations that lead to these aberrant kinases can therefore be critical in predicting the progression of a given patient’s cancer and tailoring the appropriate response.

To achieve this understanding on a more fundamental level, a team of researchers from the University of Pennsylvania’s School of Engineering and Applied Science and Perelman School of Medicine, the Children’s Hospital of Philadelphia (CHOP) and researchers at the Yale School of Medicine’s Cancer Biology Institute, have constructed molecular simulations of a mutant kinase implicated in pediatric neuroblastoma, a childhood cancer impacting the central nervous system.

Using their computational model to study the relationship between single-point changes in the kinase’s underlying gene and the altered structure of the protein it ultimately produces, the researchers revealed useful commonalities in the mutations that result in tumor formation and growth. Their findings suggest that such computational approaches could outperform existing profiling methods for other cancers and lead to more personalized treatments.

The study, published in the Proceedings of the National Academy of Sciences, was led by Ravi Radhakrishnan, Professor and chair of Penn Engineering’s Department of Bioengineering and professor in its Department of Chemical and Biomolecular Engineering, and Mark A. Lemmon, Professor of Pharmacology at Yale and co-director of Yale’s Cancer Biology Institute. The study’s first authors were Keshav Patil, a graduate student in Penn Engineering’s Department of Chemical and Biomolecular Engineering, along with Earl Joseph Jordan and Jin H. Park, then members of the Graduate Group in Biochemistry and Molecular Biology in Penn’s Perelman School of Medicine. Krishna Suresh, an undergraduate student in Radhakrishnan’s lab, Courtney M. Smith, a graduate student in Lemmon’s lab, and Abigail A. Lemmon, an undergraduate in Lemmon’s lab, contributed to the study. They collaborated with Yaël P. Mossé, Associate Professor of Pediatrics at Penn Medicine and in the division of oncology at CHOP.

“Some cancers rely on the aberrant activation of a single gene product for tumor initiation and progression,” says Radhakrishnan. “This unique mutational signature may hold the key to understanding which patients suffer from aggressive forms of the disease or for whom a given therapeutic drug may yield short- or long-term benefits. Yet, outside of a few commonly occurring ‘hotspot’ mutations, experimental studies of clinically observed mutations are not commonly pursued.”

‘RNA worked for COVID-19 vaccines. Could it be used to treat cancer and rare childhood diseases?’

William H. Peranteau, Michael J. Mitchell, Margaret Billingsley, Meghana Kashyap, and Rachel Riley (Clockwise from top left)

As COVID-19 vaccines roll out, the concept of using mRNA to fend off viruses has become a part of the public dialogue. However, scientists have been researching how mRNA can be used to in life-saving medical treatments well before the pandemic.

The “m” in “mRNA” is for “messenger.” A single-stranded counterpart to DNA, it translates the genetic code into the production of proteins, the building blocks of life. The Moderna and Pfizer COVID-19 vaccines work by introducing mRNA sequences that act as a set of instructions for the body to produce proteins that mimic parts of the virus itself. This prepares the body’s immune response to recognize the real virus and fight it off.

Because it can spur the production of proteins that the body can’t make on its own, mRNA therapies also have the potential to slow or prevent genetic diseases that develop before birth, such as cystic fibrosis and sickle-cell anemia.

However, because mRNA is a relatively unstable molecule that degrades quickly, it needs to be packaged in a way that maintains its integrity as its delivered to the cells of a developing fetus.

To solve this challenge, Michael J. Mitchell, Skirkanich Assistant Professor of Innovation in the Department of Bioengineering, is researching the use of lipid nanoparticles as packages that transport mRNA into the cell. He and William H. Peranteau, an attending surgeon in the Division of General, Thoracic and Fetal Surgery and the Adzick-McCausland Distinguished Chair in Fetal and Pediatric Surgery at Children’s Hospital of Philadelphia, recently co-authored a “proof-of-concept” paper investigating this technique.

In this study, published in Science Advances, Mitchel examined which nanoparticles were optimal in the transport of mRNA to fetal mice. Although no disease or organ was targeted in this study, the ability to administer mRNA to a mouse while still in the womb was demonstrated, and the results are promising for the next stages of targeted disease prevention in humans.

Mitchel spoke with Tom Avril at The Philadelphia Inquirer about the mouse study and its implications for treatment of rare infant diseases through the use of mRNA, ‘the messenger of life.’

Penn bioengineering professor Michael J. Mitchell, the other senior author of the mouse study, tested various combinations of lipids to see which would work best.

The appeal of the fatty substances is that they are biocompatible. In the vaccines, for example, two of the four lipids used to make the delivery spheres are identical to lipids found in the membranes of human cells — including plain old cholesterol.

When injected, the spheres, called nanoparticles, are engulfed by the person’s cells and then deposit their cargo, the RNA molecules, inside. The cells respond by making the proteins, just as they make proteins by following the instructions in the person’s own RNA. (Important reminder: The RNA in the vaccines cannot become part of your DNA.)

Among the different lipid combinations that Mitchell and his lab members tested, some were better at delivering their cargo to specific organs, such as the liver and lungs, meaning they could be a good vehicle for treating disease in those tissues.
