When a neuron in our body gets damaged, segments of RNA produce proteins that can help repair the injury. But in neurological disorders such as ALS and spinal muscular atrophy, or following spinal cord injuries, the mechanisms for moving life-essential RNA to injured sites within the cell fail. As a result, RNA molecules can’t get to where they are needed and damage becomes permanent. Researchers at Stanford have developed a technology for transporting RNA to specific locations within a neuron,…
Persistently high blood sugar and insulin resistance significantly increased the risk of worsening functional and structural heart damage during growth from adolescence to young adulthood, a new study shows. The study was conducted in collaboration between the Baylor College of Medicine in the US, the University of Bern in Switzerland, Murdoch Children’s Research Institute in Australia, the Universities of Bristol and Exeter in the UK, and the University of Eastern Finland. The results were published in the highly esteemed Diabetes…
Criegee intermediates (CIs)—highly reactive species formed when ozone reacts with alkenes in the atmosphere—play a crucial role in generating hydroxyl radicals (the atmosphere’s “cleansing agents”) and aerosols that impact climate and air quality. The syn-CH3CHOO is particularly important among these intermediates, accounting for 25-79% of all CIs depending on the season. Until now, scientists have believed that syn-CH3CHOO primarily disappeared through self-decomposition. However, in a published in Nature Chemistry, a team led by Profs. YANG Xueming, ZHANG Donghui, DONG Wenrui and FU Bina from the Dalian Institute…
It is now possible to obtain three-dimensional, high-resolution images of enzyme activity in tissue samples or whole organs—thanks to probe molecules that anchor fluorescent dyes within tissue as they are activated by enzymes. The organ being mapped is made transparent by a clearing process. As a Japanese team reported in the journal Angewandte Chemie, this allowed for visualization of differences in aminopeptidase N activity and the effects of inhibitors in mouse kidneys. Enzymes play a crucial role in regulating physiological…
Survival benefit prevails in low-, intermediate-, and high-risk subgroups Differentiated thyroid cancer patients who receive radioiodine (RAI) treatment after surgery have increased relative survival rates compared to those who do not receive the treatment. According to new research published in the April issue of The Journal of Nuclear Medicine, the clear trend for a higher long-term survival rate is observed in subgroups of patients with low- and intermediate-risk disease, while there is special benefit in high-risk disease. These findings confirm the benefit…
A novel combination of hydroxyl-enriched fullerenol and mTOR inhibitors reveals regulatory mechanisms of organelle communication networks in preclinical models, establishing a synergistic “nanomaterial + metabolic modulation” anticancer strategy. Breakthrough Cancer Strategy Hijacks Tumor Cells’ Survival Network Researchers have developed a nanoparticle-based therapy that disrupts cancer cells’ organelle communication system – the hidden network allowing tumors to resist conventional treatments. By combining multi-hydroxyl fullerene (MF) nanoparticles with mTOR inhibitors, this approach triggers the domino-like collapse of lysosomes (“cellular recycling centers”), mitochondria…
Dana-Farber Brigham Cancer Center-led phase 3 clinical trial shows that pembrolizumab before and after standard-of-care surgery significantly extends event-free survival, representing the first advance for these patients in over 20 years Immunotherapy before and after surgery improves outcomes in head and neck cancer Dana-Farber Brigham Cancer Center-led phase 3 clinical trial shows that pembrolizumab before and after standard-of-care surgery significantly extends event-free survival, representing the first advance for these patients in over 20 years Patients with locally advanced head…
Patients in a Phase 3 clinical trial who received sotorasib and panitumumab lived longer, suggesting the combination therapy could become the new standard of care. A novel combination therapy offers better outcomes for patients with KRAS G12C metastatic colorectal cancer that have stopped responding to chemotherapy, according to a Phase 3 clinical trial by researchers at City of Hope®, one of the largest and most advanced cancer research and treatment organizations in the U.S., with its National Medical Center named…
At-home testing and patient choice credited for reducing racial disparities A 20-year initiative that offered flexible options for colorectal cancer screening at a major integrated health system doubled colorectal cancer screening rates, cut cancer incidence by a third, halved deaths, and brought racial differences in outcomes to nearly zero, according to a study to be presented at Digestive Disease Week® (DDW) 2025. “By offering an effective screening approach equally to everyone, we were able to eliminate much of the disparity,”…
One of the challenges of fighting pancreatic cancer is finding ways to penetrate the organ’s dense tissue to define the margins between malignant and normal tissue. A new study uses DNA origami structures to selectively deliver fluorescent imaging agents to pancreatic cancer cells without affecting normal cells. The study, led by University of Illinois Urbana-Champaign mechanical science and engineering professor Bumsoo Han and professor Jong Hyun Choi at Purdue University, found that specially engineered DNA origami structures carrying imaging dye…
A Kobe University team was able to edit the DNA of Lactobacillus strains directly without a template from other organisms. This technique is indistinguishable from natural variation and enabled the researchers to create a strain that doesn’t produce diabetes-aggravating chemicals. Humans have improved the microorganisms we rely on for millennia, selecting variants that are better able to produce wine, yogurt, natto and many other products. More recently, direct genetic modification has emerged as a tool to exert more precise and…
Researchers from The University of Osaka discover that specific white blood cells and the amount of an inflammation protein in the blood can predict relapse of an autoimmune blood vessel disease Neutrophils, one of the immune system warriors that were thought to be all the same, turn out to be diverse. Unfortunately, these cells are also active in autoimmune diseases. New research from Japan has found that a certain subpopulation of these white blood cells can predict disease relapse at…
Multicenter study suggests stroke prevention guidelines may underestimate risk in patients with symptomatic mild carotid stenosis Ischemic stroke remains one of the leading causes of death and long-term disability worldwide, with narrowing of the carotid artery due to atherosclerosis contributing to up to 30% of all cases. For decades, medical practitioners have primarily relied on the degree of carotid narrowing (stenosis) to assess the risk of stroke and determine the best treatment options. However, mounting evidence suggests that this approach…
Noninvasive method detects anemia in children by analyzing smartphone photos of the eye’s conjunctiva Anemia, a condition marked by low levels of hemoglobin in the blood, affects nearly 2 billion people worldwide. Among them, school-age children in low- and middle-income countries are particularly vulnerable. Left untreated, anemia in children can interfere with growth, learning, and overall development. Detecting the condition early is essential, but standard diagnostic methods require blood samples and lab equipment—resources that are often unavailable in low-income areas….
Amsterdam UMC-developed algorithm, based on the data of more than half a million patients, may soon offer GPs the chance to accelerate a diagnosis GPs may soon be able to identify patients with an increased risk of lung cancer up to 4 months earlier than is currently the case. The GP should be able to simply identify patients during a consultation with an algorithm created by researchers at Amsterdam UMC based on the data of more than half a million…
Researchers at Baylor College of Medicine, Texas Children’s Hospital, the Hospital for Sick Children in Toronto and collaborating institutions reveal in Nature Cell Biology a strategy that helps medulloblastoma, the most prevalent malignant brain tumor in children, spread and grow on the leptomeninges, the membranes surrounding the brain and spinal cord. They discovered a novel line of communication between metastatic medulloblastoma and leptomeningeal fibroblasts that mediates recruitment and reprogramming of the latter to support tumor growth. The findings suggest that…
Researchers at Tulane University have identified a potential new way to treat idiopathic pulmonary fibrosis (IPF), a deadly and currently incurable lung disease that affects more than 3 million people worldwide. IPF is rapidly progressive and causes scarring in the lungs, making it difficult to breathe. Approximately 50% of patients die within three years of diagnosis, and current treatments can only slow the disease — not stop or reverse it. In a study published in the Journal of Clinical Investigation, Tulane scientists…
