Penn Medicine: Made to Order at the Synapse: Dynamics of Protein Synthesis at Neuron Tip is Basis for Memory and Learning
Protein synthesis in the extensions of nerve cells, called dendrites, underlies long-term memory formation in the brain, among other functions.
Penn Researchers Pinpoint Molecular Path that Makes Antidepressants Act Quicker
The reasons behind why it often takes people several weeks to feel the effect of newly prescribed antidepressants remains somewhat of a mystery – and likely, a frustration to both patients and physicians.
Two Penn Students Awarded HHMI International Research Fellowships
Two doctoral students from the University of Pennsylvania, Nam Woo Cho of the Perelman School of Medicine and Maryam Yousefi of the School of Veterinary Medicine, have received International Student Research Fellowships from the Howar
Penn Medicine: Balancing Act: Cell Senescence, Aging Related to Epigenetic Changes
One way cells promote tumor suppression is through a process called senescence, an irreversible arrest of proliferation. Senescence is thought to be associated with normal aging, but is also a protective measure by the body against run-away cell replication.
Minor and Major: Penn Study Finds A New Gene Expression Mechanism
A rare, small RNA turns a gene-splicing machine into a switch that controls the expression of hundreds of human genes.
Tumors Form Advance Teams to Ready Lungs for Spread of Cancer, Finds Penn Study
Cancer metastasis requires tumor cells to acquire properties that allow them to escape from the primary tumor site, travel to a distant place in the body, and form secondary tumors.
Penn Study Shows How Viruses in Gut Bacteria Change
Humans are far more than merely the sum total of all the cells that form the organs and tissues.
Penn: Stem Cell in Heart and Lung Development Explains Adaption for Life on Land
The evolution of adaptations for life on land have long puzzled biologists – are feathers descendents of dinosaur scales, how did arms and legs evolve from fins, and from what ancient fish organ did the lung evolve?
A Bad Alliance: Rare Immune Cells Promote Food-Induced Allergic Inflammation in the Esophagus, Finds Penn Study
Food is an integral part of life; but, for some, it can be harmful. Allergic inflammation caused by inappropriate immune responses to some types of food has become a major public health issue. Over the past ten years, the prevalence of food allergies has increased by nearly 20 percent, affecting an estimated six million people in the U.S.
Penn: Pluripotent Stem Cells Made From Pancreatic Cancer Cells Show Progression
Pancreatic cancer carries a dismal prognosis. According to the National Cancer Institute, the overall five-year relative survival for 2003-2009 was 6 percent.
