DEAF1 gene identified as muscle aging regulator
Scientists have discovered a molecular switch that helps explain why exercise keeps aging muscles healthy. By reducing levels of a gene called DEAF1, physical activity allows older muscles to clear out damage, repair themselves, and maintain function. The finding, published in ScienceDaily, opens new avenues for treating age-related muscle decline without requiring intense exercise.
New cholesterol test could prevent more heart attacks
A new study suggests that apoB, a blood test measuring harmful cholesterol particles, outperforms standard LDL cholesterol testing for deciding who needs more intensive treatment. Researchers found it could prevent more heart attacks by better identifying at-risk patients. Millions may currently be getting the wrong cholesterol test.
Statin risk calculator offers personalized guidance
Scientists at the University of Oxford have created a calculator that predicts a person's individual risk of serious muscle disorders from statin use. The tool aims to help patients and doctors make more informed decisions about cholesterol-lowering therapy, addressing one of the most common reasons patients stop taking statins.
