“Supermeres” may carry clues to cancer, Alzheimer’s disease and COVID-19

Vanderbilt researchers have discovered a nanoparticle released from cells, called a “supermere,” which contains enzymes, proteins and RNA associated with multiple cancers, cardiovascular disease, Alzheimer’s disease and even COVID-19.

Research by Robert Coffey, MD, left, Dennis Jeppesen, PhD, and colleagues has revealed a new way cells shed DNA into the bloodstream.

Discovery aids search for cancer biomarkers

A report by researchers at Vanderbilt University Medical Center has shattered conventional wisdom about how cells, including cancer cells, shed DNA into the bloodstream: they don’t do it by packaging the genetic material in tiny vesicles called exosomes.
