Mysterious RNA led scientists to a hidden layer of cancer
A Cell Reports Medicine study identifies a hidden class of cancer-specific 'orphan' RNAs across dozens of tumor types. These RNAs form precise molecular barcodes that classify tumor type and subtype, with some functioning as oncogenic drivers. Because many are released into the bloodstream, simple blood tests could monitor treatment response and predict patient survival.
Why it mattersBlood-accessible orphan RNAs found in breast cancer justify prioritizing blood-test development for treatment monitoring.
