Long-standing psychological traits, including neuroticism and a lack of purpose, track distinct molecular pathways in Alzheimer’s dementia, according to a multi-omics study published in Translational Psychiatry. Researchers from the Religious Orders Study (ROS) and the Rush Memory and Aging Project (MAP) found that while traditional pathology and genetic risk factors identify overall disease susceptibility, these … Read more
The loss of the transcription factor GATA6 acts as a biological switch that reprograms colorectal cancer cells to metastasize to the liver, according to research published June 22 in Cell Stem Cell. By silencing this “identity keeper,” cancer cells adopt a flexible, fetal-like state that allows them to travel through the bloodstream and colonize distant … Read more
High-dose fish oil supplements do not improve memory or prevent brain cell loss in older adults at risk for Alzheimer’s disease, according to a study published in eBioMedicine by researchers at Keck Medicine of USC. Despite evidence that the omega-3 fatty acid DHA successfully reaches the brain, the two-year clinical trial found no significant cognitive … Read more
A new study published in BMC Medicine reveals that a specific genetic variant linked to a preference for onions is associated with lower blood pressure and a 14% reduced risk of type 2 diabetes. Researchers from the Monell Chemical Senses Center and their international partners used Mendelian randomization to determine that these genetic markers act … Read more
Researchers at the Institute of Science and Technology Austria (ISTA) have identified shared molecular pathways across diverse autism spectrum disorder (ASD) genetic models, according to a study published in Nature. By utilizing single-nucleus multi-omics sequencing, the team discovered that while genetic mutations differ, they often trigger identical developmental delays in brain cell maturation. This finding … Read more
How Do Phages Shape Microbial Communities? Researchers at Rice University have developed a revolutionary method to track how bacteriophages (phages) interact with bacteria, revealing new insights into microbial ecosystems. Published in Nature Communications, the study uses an RNA-based barcoding system to map phage-host relationships in real-world environments, according to Lauren Stadler, associate professor of civil … Read more
Obesity and Cancer Risk: How a Landmark Study Rewrote the Rules A new meta-analysis of 1.5 million cancer cases reveals that excess body weight may increase the risk of 19 types of cancer—far more than previously thought. The findings, published in Nature Metabolism, also expose stark regional and gender disparities, challenging global health policies and … Read more
Researchers from the Wellcome Sanger Institute and the Francis Crick Institute have identified a genetic marker, HLA-DRB1*01:03, that correlates with more severe ulcerative colitis and Crohn’s disease. Published in The Lancet Gastroenterology and Hepatology, the study suggests that genetic testing could help clinicians identify high-risk patients for earlier intervention with advanced therapies. How does the … Read more
Screening patients for Li-Fraumeni syndrome (LFS) costs approximately nine times less than treating the cancer-related complications of the condition, according to new research presented at the European Society of Human Genetics conference. The study, conducted by the EU PREVENTABLE project, found that preventive surveillance costs an average of €6,046 per patient, compared to €53,906 for … Read more
A patient’s genetic ancestry can significantly influence cancer progression and survival rates, according to research presented at the European Society of Human Genetics conference. By integrating ancestry data with tumor sequencing, doctors can more accurately predict patient outcomes, particularly in pancreatic and breast cancers, without requiring additional clinical tests. How does genetic ancestry influence cancer … Read more
