Mount Sinai Researchers Discover Novel Nanoparticles in Blood With Potential to Transform Cancer Diagnosis

Scientists at the Icahn School of Medicine at Mount Sinai have identified a new class of RNAs packed into tiny particles known as extracellular vesicles (EVs) that could revolutionize how cancer and other diseases are diagnosed. The team found that these molecules undergo changes when cancer is present, suggesting their potential as biomarkers for detecting prostate cancer or as targets for therapy.
