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. […]

Variable number tandem repeats modulate genes associated with Alzheimer’s disease, obesity, cancer and other conditions. An international team of researchers led by computer scientists at the University of California San Diego have identified 163 variable number tandem repeats (VNTRs) that actively regulate gene expression. In a paper published in Nature […]

Brain tumors known as glioblastomas are among the most aggressive and malevolent forms of cancer. Median survival time without treatment is just nine months; with standard of care surgery and chemoradiation, it’s 15 to 16 months. Patients rarely survive more than a few years. In only a very small subset […]

Exposure to phthalates, a class of chemicals widely used in packaging and consumer products, is known to interfere with normal hormone function and development in human and animal studies. Now researchers have found evidence linking pregnant women’s exposure to phthalates to altered cognitive outcomes in their infants. Most of the […]

Scientists have identified new genetic clues in people who have had small and often apparently ‘silent’ strokes that are difficult to treat and a major cause of vascular dementia, according to research led by the University of Cambridge and published in The Lancet Neurology. Researchers discovered changes to 12 genetic regions […]

Scientists at the University of Cambridge have shown in animal studies that gene therapy may help repair some of the damage caused in chronic neurodegenerative conditions such as glaucoma and dementia. Their approach demonstrates the potential effectiveness of gene therapy in polygenic conditions – that is, complex conditions with no […]
