Variation of extrachromosomal circular DNA in cancer cell lines

Abstract excerpt

The presence of oncogene carrying eccDNAs is strongly associated with carcinogenesis and poor patient survival. Tumour biopsies and in vitro cancer cell lines are frequently utilized as models to investigate the role of eccDNA in cancer. However, eccDNAs are often lost during the in vitro growth of cancer cell lines, questioning the reproducibility of studies utilizing cancer cell line models. Here, we conducted...
