Extrachromosomal circular DNA (ecDNA) represents a distinct genomic entity that exists independent of the primary chromosomal structure. In cancer, ecDNA is recognised as a potent driver of oncogene ...

Scientists have discovered a way to target elusive circular fragments of DNA that drive the survival of some of the most aggressive cancers, paving the way for future treatments. In three ...

Extrachromosomal DNAs (ecDNAs) are circular DNA structures located in the nuclei of cells outside chromosomes. They were originally discovered in chromosome spreads of cells obtained from embryonal ...

Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA strands carry a negative charge, and they do not cross that wall easily.
