Three panels show fluorescent images of therapeutic gene LRIT3, which corrects a form of night blindness

Correcting night blindness in dogs

Researchers in the School of Veterinary Medicine and colleagues have developed a gene therapy that restores dim-light vision in dogs with a congenital form of night blindness, offering hope for treating a similar condition in people.

A new study finds genome refolding contributes to resistance to cancer therapy

While gene mutations can lead to drug resistance, researchers in the Perelman School of Medicine have identified an important, non-genetic adaptation that could also drive resistance to targeted therapy in T cell leukemia, a type of blood cell cancer.

‘Mapping’ pancreatic cells at the development of Type 1 diabetes

Penn Medicine researchers examine of the underpinnings of the disease by creating a “map” to chart pancreatic islet cells over time.

First gene-editing treatment injected into the blood reduces toxic protein for up to 1 year

Kiran Musunuru of the Perelman School of Medicine commented on an experimental gene-editing treatment for a condition that has already responded well to approved drugs. “I think people are generally assuming that the clinical outcomes [from the gene-editing treatment] will follow,” he said.

How one researcher is helping us better understand the brain through epigenetics

Erica Korb, assistant professor of genetics, combines microscopy, bioinformatics, biochemistry, and behavioral testing to better understand gene expression and its impact on brain development.

Changing the identity of cancer cells to eliminate them

A team led by the School of Veterinary Medicine’s M. Andrés Blanco has uncovered a new target for treating certain blood cancers that works by removing an obstacle to their maturation.

Novel gene therapy for hemophilia A

The multicenter study, led by researchers at the Perelman School of Medicine and Children’s Hospital of Philadelphia, showed improved and sustained production of a needed clotting factor and reduced bleeding events.

New gene-editing technique can ‘turn on’ enzymes that cause DNA base mutations

The novel Penn method of splitting specific mutator enzymes and then triggering them to reconstitute has been patented, and allows for new possibilities in biologic and therapeutic research, including cancer.

Moving past conflation of race and genetics

Race is not genetic. Race is a social and political construct. However, the conflation of race and genetics is one way that racism persists in medicine and research.

Home DNA tests can lead to shock and trauma, but mental health resources are scarce

Dana Farengo Clark of the Abramson Cancer Center said many people come into the Center looking for support after taking a home DNA test that revealed their risk, as well as family members’ risk, for cancer. “A piece of the psychology of this is not only getting the result for yourself but then being the gatekeeper of that information,” she said.
