Specific type of DNA could be a target of future cancer therapies

Research published in Nature Genetics on Oct.14, by Yale Cancer Center researchers at Yale School of Medicine, found a higher concentration of a specific kind of DNA - extrachromosomal or ecDNA - in more aggressive and advanced cancers that could mark them as targets for future therapies.

Using data available from The Cancer Genome Atlas, the International Cancer Genomics Consortium, the Hartwig Medical Foundation, and the Glioma Longitudinal Analysis Consortium, the researchers considered more than 8,000 tumor samples, divided between newly diagnosed untreated tumors and those that had been through previous treatments such as chemotherapy, radiation, and others.
