ERBB2 and Epstein-Barr virus infection: The panel also included several SNU (Seoul National University) GC cells, each with some type of genomic aberration (including single-nucleotide variants, ERBB2 gene amplification, etc.), the well-known GC cell line SNU-216, having both ERBB2 gene amplification and protein overexpression [18], the cell line NCC-24, originated from an Epstein-Barr virus infection [38], and several other highly distinctive lines (e.g., the MKN series derived from Japanese patient GC metastases) [39].
