Integrated genomic and transcriptomic profiling of glioblastoma reveals ecDNA-driven heterogeneity and microenvironmental reprogramming.
Tang et al. provide a comprehensive genomic and transcriptomic characterization of extrachromosomal DNA (ecDNA) in glioblastoma. They reveal that EGFR ecDNA shapes transcriptional subtypes and reprograms the tumor microenvironment by stabilizing metabolically active tumor-associated macrophages. These findings uncover mechanistic links between ecDNA architecture and glioblastoma progression, highlighting potential therapeutic vulnerabilities.
The corpus callosum is critical for nearly everything the brain does, from coordinating the movement of our limbs in sync to integrating sights and sounds, to higher-order thinking and decision-making. Abnormalities in its shape and size have long been linked to disorders such as ADHD, bipolar disorder, and Parkinson’s disease. Until now, the genetic underpinnings of this vital structure remained largely unknown.
In the new study, published in Nature Communications, the team analyzed brain scans and genetic data from over 50,000 people, ranging from childhood to late adulthood, with the help of a new tool the team created that leverages artificial intelligence.
“We developed an AI tool that finds the corpus callosum in different types of brain MRI scans and automatically takes its measurements,” said co-first author of the study. Using this tool, the researchers identified dozens of genetic regions that influence the size and thickness of the corpus callosum and its subregions.
The study revealed that different sets of genes govern the area versus the thickness of the corpus callosum—two features that change across the lifespan and play distinct roles in brain function. Several of the implicated genes are active during prenatal brain development, particularly in processes like cell growth, programmed cell death, and the wiring of nerve fibers across hemispheres.
Notably, the study found genetic overlap between the corpus callosum and the cerebral cortex—the outer layer of the brain responsible for memory, attention, and language—as well as with conditions such as ADHD and bipolar disorder.
For the first time, a research team has mapped the genetic architecture of a crucial part of the human brain known as the corpus callosum—the thick band of nerve fibers that connects the brain’s left and right hemispheres. The findings open new pathways for discoveries about mental illness, neurological disorders and other diseases related to defects in this part of the brain.
Amid concerns about the simultaneous spread of multiple respiratory diseases, such as colds and influenza, with the change of seasons in current times, a clinical study has scientifically proven that kimchi, a traditional Korean fermented food, enhances the function of human immune cells and maintains the balance of the immune system.
The World Institute of Kimchi has reported the results of a single-cell genetic analysis that suggests that kimchi consumption has immunomodulatory effects, which include the suppression of excessive immune responses while simultaneously enhancing defense functions.
The results of the research are published in npj Science of Food.
A study of 76,000 Swedish adults found that strict adherence to the Nordic diet is linked to a 23 percent drop in premature death plus lower cancer and heart disease mortality.
A low dose of aspirin each day may significantly reduce the chances of colon and rectal cancer returning in certain cases, a new clinical trial has found.
Led by researchers from the Karolinska Institute and Karolinska University Hospital in Sweden, the study involved 626 people with stages 1 to 3 colon or rectal cancer, and specific genetic mutations in the cancer tumors.
Previous studies have suggested that cancers with these mutations – specifically in the PIK3 signaling pathway – could be targeted by aspirin, but this is the first time the hypothesis has been tested in a randomized clinical trial.
Genetic engineering and human enhancement are no longer science fiction — they’re here right now. In this episode of Longevity Science News, we explore the rise of gene therapy, anti-aging biotechnology, and the first wave of GMO Humans using real genetic enhancements to increase muscle, extend telomeres, boost IQ, and slow biological aging.
If you’re interested in longevity, life extension, biohacking, genetic modification, or cutting-edge anti-aging research, this video breaks down everything you need to know about the future of human evolution — and the people already jumping in.

DNA methylation has shown great potential in Alzheimer’s disease (AD) blood diagnosis. However, the ability of long non-coding RNAs (lncRNAs), which can be modified by DNA methylation, to serve as noninvasive biomarkers for AD diagnosis remains unclear.
We performed logistic regression analysis of DNA methylation data from the blood of patients with AD compared and normal controls to identify epigenetically regulated (ER) lncRNAs. Through five machine learning algorithms, we prioritized ER lncRNAs associated with AD diagnosis. An AD blood diagnosis model was constructed based on lncRNA methylation in Australian Imaging, Biomarkers, and Lifestyle (AIBL) subject and verified in two large blood-based studies, the European collaboration for the discovery of novel biomarkers for Alzheimer’s disease (AddNeuroMed) and the Alzheimer’s Disease Neuroimaging Initiative (ADNI). In addition, the potential biological functions and clinical associations of lncRNAs were explored, and their neuropathological roles in AD brain tissue were estimated via cross-tissue analysis.
We characterized the ER lncRNA landscape in AD blood, which is strongly related to AD occurrence and process. Fifteen ER lncRNAs were prioritized to construct an AD blood diagnostic and nomogram model. The receiver operating characteristic (ROC) curve and the decision and calibration curves show that the model has good prediction performance. We found that the targets and lncRNAs were correlated with AD clinical features. Moreover, cross-tissue analysis revealed that the lncRNA ENSG0000029584 plays both diagnostic and neuropathological roles in AD.
Every second, trillions of tiny parcels travel through your bloodstream—carrying vital information between your body’s cells. Now, scientists at the Baker Heart and Diabetes Institute have opened this molecular mail for the first time, revealing its contents in astonishing detail.
In research published in Nature Cell Biology, Professor David W. Greening and Dr. Alin Rai have mapped the complete molecular blueprint of extracellular vesicles (EVs)—nanosized particles in blood that act as the body’s secret messengers.
For decades, researchers have known that EVs exist, ferrying proteins, fats, and genetic material that mirror the health of their cells of origin. But because blood is a complex mixture—packed with cholesterol, antibodies, and millions of other particles—isolating EVs has long been one of science’s toughest challenges.
