It’s a long way from DNA to RNA to protein, and only about two percent of a person’s genome is eventually converted into proteins.

A team led by researchers from the Perelman School of Medicine at the University of Pennsylvania found that a susceptibility gene for type 1 diabetes regulates self-destruction of the cell’s energy factory. They report their findings this week in Cell.

Autoimmune disease occurs when the body's own natural defense system rebels against itself.  One example is pemphigus vulgaris (PV), a blistering skin disease in which autoantibodies attack desmoglein 3 (Dsg3), the protein that binds together skin cells. 

A team of researchers led by Penn Medicine anesthesiologists have pinpointed the “top five” most common perioperative procedures that are supported by the least amount of clinical evidence, in an effort to direct providers to make more cost-effective treatment decisions.

When a woman experiences a stressful event early in pregnancy, the risk of her child developing autism spectrum disorders or schizophrenia increases. Yet how maternal stress is transmitted to the brain of the developing fetus, leading to these problems in neurodevelopment, is poorly understood. 

Bringing clarity to a decades-long debate, a national team of researchers led by experts from the Perelman School of Medicine at the University of Pennsylvania has found that adding clot-busting medications known as thrombolytics to conventional approaches when treating sudden-onset pulmonary embolism patients is associated with 47 perce

Using powerful, newly developed cell culture and mouse  models of sporadic Parkinson’s disease (PD), a team of researchers from the Perelman School of Medicine at the University of Pennsylvania, has demonstrated that immunotherapy with specifically targeted antibodies may block the development and spread of PD pathology in the brain.

Obesity and obstructive sleep apnea (OSA) tend to co-exist and are associated with a variety of cardiovascular risk factors, including inflammation, insulin resistance, abnormal cholesterol, and high blood pressure.

The human body is comprised of roughly 10 times more bacterial cells than human cells. In healthy people, these bacteria are typically harmless and often helpful, keeping disease-causing microbes at bay. But, when disturbances knock these bacterial populations out of balance, illnesses can arise. Periodontitis, a severe form of gum disease, is one example.

Researchers at the Center of Excellence in Environmental Toxicology (CEET), Perelman School of Medicine at the University of Pennsylvania, have been awarded a $10 million grant from the National Institute for Environmental Health Sciences (NIEHS) over the next f
