SNU-668 Cells

The SNU-668 cell line is a human gastric carcinoma model originally derived from the poorly differentiated adenocarcinoma tissue of the stomach. This cell line has been widely used in studies of gastric cancer pathogenesis, signaling mechanisms, and drug responsiveness. Genomic characterization reveals that SNU-668 carries frequent mutations and chromosomal aberrations commonly observed in diffuse-type gastric cancers. Notably, it shows alterations in key oncogenic pathways such as TP53 mutation and possible activation of PI3K/AKT signaling, which may contribute to its tumorigenic properties and therapy resistance.

SNU-668 has also been included in comprehensive multi-omics profiling projects such as the Cancer Cell Line Encyclopedia (CCLE), where it was assessed for transcriptomic, genomic, methylation, and proteomic signatures. The cell line exhibits distinct DNA methylation patterns and global histone modification profiles, which may play roles in epigenetic regulation of gene expression. Additionally, analysis of dependency maps has suggested lineage-specific vulnerabilities that could inform targeted therapy strategies for diffuse gastric carcinomas. As a model for stomach cancer with Asian ethnic background origin, SNU-668 continues to be an important tool in the preclinical evaluation of molecularly guided therapeutics.
