摘要:
Extrachromosomal DNA, referred to as extrachromosomal DNA (ecDNA), was found in most cancers and nearly absent in normal cells. The properties of ecDNA enable tumor cells to be more responsive to various environments. The non-Mendelian genetic mechanism of ecDNA could arouse increasing tumor heterogeneity. Besides, ecDNA would promote tumor invasiveness and provide resistance mechanisms associated with poorer survival consequences. Furthermore, ecDNA could profoundly impact oncogene activation, genome instability, tumor heterogeneity, etc. Consequently, they may offer potential possibilities f...
