Method development

ecDNA is small and heavily rearranged, and existing methods are not sufficient to characterize it. We have therefore developed our own: scEC&T-seq, an experimental and computational technique that profiles...

Understanding ecDNA maintenance and transcription

It is remarkable that cancer cells can maintain and transcribe ecDNA, which is non-chromosomal, circular and does not have centromeres. We hypothesize that specific processes are necessary for ecDNA...

Mechanisms and consequences of ecDNA evolution

ecDNA functions as an evolutionary hotspot, allowing cancers to escape therapy after an initially promising response. We have shown that ecDNA in neuroblastoma is a major source of somatic...

Emergence of ecDNA as an oncogenic driver

In recent years, it has become apparent that extrachromosomal DNA (ecDNA) is a vehicle for oncogene amplification in most cancers and is associated with worse disease prognosis. What is...
