Penn Medicine: Sleep-Deprived Mice Show Connections Among Lack of Shut-eye, Diabetes, Age
Sleep, or the lack of it, seems to affect just about every aspect of human physiology. Yet, the molecular pathways through which sleep deprivation wreaks its detrimental effects on the body remain poorly understood. Although numerous studies have looked at the consequences of sleep deprivation on the brain, comparatively few have directly tested its effects on peripheral organs.
Five Penn Faculty Earn Distinction as AAAS Fellows
Five faculty members from the University of Pennsylvania have been named fellows of the American Association for the Advancement of Science.
Epigenetic Changes May Explain Chronic Kidney Disease, Penn Study Shows
The research of physician-scientist Katalin Susztak, MD, PhD, associate professor of Medicine in the Renal Electrolyte and Hypertension Division, at the Perelman School of Medicine, University of Pennsylvania, strives to understand the molecular roots an
Penn Medicine: Paths Not Taken: Notch Signaling Pathway Keeps Immature T Cells on the Right Track
The lab of Avinash Bhandoola, PhD, professor of Pathology and Laboratory Medicine, has studied the origins of T cells for many years. One protein called Notch, which has well-known roles in the development of multiple tissues, plays an essential role in triggering T-cell development.
Penn Medicine: Targets of Anticancer Drugs Have Broader Functions than What Their Name Suggests
Drugs that inhibit the activity of enzymes called histone deacetylases (HDACs) are being widely developed for treating cancer and other diseases, with two already on the market. Researchers at the Perelman School of Medicine, University of Pennsylvania, show that a major HDAC still functions in mice even when its enzyme activity is abolished, suggesting that the beneficial effects of HDAC inhibitors may not actually be through inhibiting HDAC activity, and thus warranting the reassessment of the molecular targets of this class of drugs.
Penn Researchers Identify Molecular Link Between Gut Microbes and Intestinal Health
It’s well established that humans maintain a symbiotic relationship with the trillions of beneficial microbes that colonize their bodies. These organisms, collectively called the microbiota, help digest food, maintain the immune system, fend off pathogens, and more.
Penn Medicine: Cell Nucleus Protein in Brown Fat Cells Governs Daily Control of Body Temperature
For nearly 300 years, investigators have known that body temperature follows a circadian, or 24-hour, rhythm, with a peak during the day and a low at night.
Institute of Medicine Elects Seven New Members from Penn Medicine
Seven professors from the Perelman School of Medicine have been elected members of the Institute of Medicine (IOM), one of the nation's highest honors in biomedicine.
Penn Medicine Names First Leader of Precision Medicine to Speed Delivery of Tailored Treatments to Patients
D. Gary Gilliland, MD, PhD, has been named the inaugural Vice Dean and Vice President for Precision Medicine, a newly created role to position Penn Medicine as the nation’s top leader in the delivery of individualized medicine.
Penn's FitzGerald Named Ohio State Heart Program's 2013 Schottenstein Laureate
