A new study from researchers at the Perelman School of Medicine at the University of Pennsylvania found significant disparities in the use of sodium-glucose cotransporter 2 (SGLT2) inhibitors, a class of drugs proven to treat type 2 diabetes, with usage remaining low with Black, Asian, and lower-income groups despite an […]

A team led by scientists at the Perelman School of Medicine at the University of Pennsylvania has illuminated the functions of mysterious structures in cells called “nuclear speckles,” showing that they can work in partnership with a key protein to enhance the activities of specific sets of genes. The discovery, […]

Like a stern bodyguard for the central nervous system, the blood-brain barrier keeps out anything that could lead to disease and dangerous inflammation—at least when all is functioning normally. That may not be the case in people with schizophrenia and other mental disorders, suggest new findings from a team led […]

Published in the Advanced Functional Materials, University of Minnesota researcher Hongbo Pang led a cross-institutional study on improving the efficacy of nucleotide-based drugs against prostate cancer and bone metastasis. In this study, Pang and his research team looked at whether liposomes, when integrated with the iRGD peptide, will help concentrate antisense oligonucleotides […]

Before COVID-19, there was another public health crisis that captured headlines around the world: the Zika virus outbreak of 2015-16, which became an epidemic as it spread through Brazil and the Americas. The mosquito-borne virus was perhaps best known for causing significant birth defects, most prominently microcephaly, which can cause an […]

In today's open access paper, researchers report that long-term supplementation with nicotinamide riboside in mice, starting from mid-life and continuing into old age, slows the pace of osteoporosis. The extracellular matrix of bone tissue is constantly remodeled over time, broken down by osteoclasts and built up by osteoblasts. Osteoporosis is […]

Identification of neural circuits clarifies motor vs. cognitive symptoms, aiding efforts to improve treatments. Parkinson’s disease (PD) is well known as a debilitating disease that gradually worsens over time. Although the disease’s progression has been largely tied to the loss of motor functions, non-motor symptoms, including the loss of cognitive […]

Map of basal ganglia connectivity uncovers key links with implications for range of disorders. Thousands of our daily activities, from making coffee to taking a walk to saying hello to a neighbor, are made possible through an ancient collection of brain structures tucked away near the center of the cranium.
