Frequent Mutations in TP53 and CDKN2A Found by Next-Generation Sequencing of Head and Neck Cancer Cell Lines

To conduct high-throughput mutational analysis in 6 commonly used head and neck cancer cell lines. Comprehensive mutation analysis of primary head and neck squamous cell carcinoma (HNSCC) tumors has recently been reported, and mutations in the NOTCH receptors, TP53 and CDKN2A, were key findings. Established cell lines are valuable tools to study cancer in vitro. Similar high-throughput mutational analysis of head and neck cancer cell lines is necessary to confirm their mutational profile.
