Abstract | Hypopharyngeal squamous cell carcinoma (HPSCC) has the worst prognosis among head and neck squamous cell carcinomas. The lack of available tumor cell lines poses a significant obstacle to the development of efficient treatments for HPSCC. In this study, we successfully established a novel cell line, named CZH1, from the postcricoid region of a Chinese male patient with a T3N0M0 HPSCC. Short tandem repeat analysis confirmed the uniqueness of CZH1. The cell line was characterized by its phenotypes, biomarkers, and genetics. Importantly, CZH1 cells retained the typical features of epithelial malignancy, similar to the primary tumor tissue. Furthermore, CZH1 demonstrated a greater capacity for invasion and increased susceptibility to irradiation in comparison to FaDu, which is the most commonly used HPSCC cell line. Whole-exome sequencing analysis revealed that CZH1 cells had typical genomic features of HNSCC, including mutations of TP53 and amplifications of multiple transcripts. Therefore, our newly developed CZH1 cell line could serve as an efficient tool for the in vitro investigation of the etiology, pathogenesis, and preclinical treatment of HPSCC. |
