Specifically, the HCC-827 cell-line DNA (Cat #: CRL-2868DQ, ATCC) containing EGFR amplification, SK-BR-3 (Cat #: HTB-30, ATCC) containing ERBB2/HER2 amplification, and CRL-5909 (Cat #: NCI-H1993, ATCC) containing MET amplification were evaluated for CNA. Here, ERBB2 is linked to hepatocellular carcinoma.
