IDENTIFICATION OF EPIGENETIC ALTERATIONS IN DNA ISOLATED FROM EXOSOMES

摘要

The present invention provides methods of diagnosing and prognosing disease by analyzing the methylation status of exosomal DNA. In particular, exosomal DNA, in particular exosomal DNA isolated from exosomes that originated from a diseased cell, is analyzed for either a global methylation fingerprint or for a particular methylation status at one or more genomic loci, thereby providing information regarding the disease-state of the originated cell.
