USE OF DOUBLE-STRANDED DNA IN EXOSOMES: A NOVEL BIOMARKER IN CANCER DETECTION

摘要

The present invention is directed to methods of prognosing, treating, or managing treatment of cancer in a subject. These methods involve selecting a subject having cancer, obtaining, from the selected subject, a sample containing exosomes, recovering the exosomes from the sample, and isolating the double-stranded DNA from within the exosomes. The isolated double-stranded DNA is then used to detect the presence or absence of one or more genetic mutations associated with cancer, quantify the amount of isolated double-stranded DNA from the recovered exosomes in the sample, detect the methylation status of the isolated double- stranded DNA, or quantify the amount isolated double-stranded DNA able to enter a recipient cell. The prognosing, treating, or managing treatment is carried out based on this information.
