Blood-based test could personalize treatment for patients with HPV-associated throat cancer

Researchers at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) are advancing the understanding of a promising blood test that could personalize treatment and surveillance for patients with human papillomavirus (HPV)-associated throat cancer. The research, published in JAMA Otolaryngology – Head … Read more

DNA damage in gray matter neurons linked to MS progression

For decades, multiple sclerosis research has focused on myelin, the insulation around the brain’s wiring. Scientists paid less attention to another loss that was happening in parallel: neurons in the cortex, the seat of higher thinking and cognition, were quietly dying. A team led by UC San Francisco, University of Cambridge, and Cedars-Sinai Medical Center … Read more

Sleep duration and genetics interact to affect functional health

Lifestyle-behavioral factors and socioeconomic status play an important role in shaping healthy aging, but their effects may differ depending on your DNA, according to a new international study led by Adelaide University researchers. The study is the first of its kind to show that diet quality, physical activity, sleep, smoking, education, employment and social engagement … Read more

Chronic colitis reshapes colon stem cells in ways that can accelerate tumour growth

Even after inflammation resolves, colonic stem cells can retain a hidden molecular memory that increases the likelihood of later tumour growth, offering a new mechanistic link between chronic inflammatory disease and cancer risk. Study: Epigenetic memory of colitis promotes tumour growth. Image Credit: Antonio Marca / Shutterstock In a recent study published in the journal Nature, … Read more

Scientists discover how brain development programs fuel pediatric tumors

A team of researchers at Baylor College of Medicine, St. Jude Children’s Research Hospital, Texas Children’s Hospital, and collaborating institutions reveals in the journal Nature a novel mechanism that drives the development of pediatric supratentorial ependymoma (EPN), the third most common pediatric brain tumor. The findings suggest potential new approaches to treat these aggressive and … Read more

New Research Links Daily Multivitamins to Slower Biological Aging

In a randomized clinical trial of older adults, researchers found that taking multivitamins for two years modestly slowed epigenetic markers of aging — equivalent to roughly four months less biological aging compared with a placebo. Li et al. evaluated the two-year effect of daily multivitamin-multimineral supplements and cocoa extract (500 mg cocoa flavanols per day, including … Read more

DNA origami vaccine platform shows promise against multiple infectious viruses

The COVID-19 pandemic brought messenger RNA (mRNA) vaccines to the forefront of global health care. After their clinical trial stages, the first COVID-19 mRNA vaccine was administered on 8 December 2020 and mathematical models suggest that mRNA vaccines prevented at least 14.4 million deaths from COVID-19 in the first year alone. Their extraordinary effectiveness in having … Read more

FOXJ3 gene identified as the critical link between abnormal brain development and epilepsy

Researchers have discovered that mutations in the FOXJ3 gene act as a “master switch” failure, disrupting how the brain builds its layers and leading to FCD, a primary cause of drug-resistant epilepsy. The study reveals how FOXJ3 controls the formation of brain cortical layers during brain development by regulating the PTEN–mTOR signaling pathway. The PTEN-mTOR … Read more
