HNO41 Cells

The HNO41 cell line is derived from a hypopharyngeal squamous cell carcinoma, a type of head and neck squamous cell carcinoma (HNSCC). This cell line has been characterized by several chromosomal aberrations, including DNA copy number gains in chromosomal regions such as 3q23-qter, 5p, 7p, 7q21-q22, 8q22.2-qter, 9q22-qter, and 11q13. These regions are known to harbor oncogenes that contribute to tumor progression, making HNO41 a valuable model for studying the molecular mechanisms underlying hypopharyngeal cancer. In addition to its genetic profile, HNO41 has been analyzed for its expression of angiogenic growth factors, which are critical in tumor development and metastasis. The cell line exhibits strong expression of vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF), among others. These factors are involved in promoting angiogenesis, the formation of new blood vessels, which is a key process in tumor growth and metastasis. The presence of these factors in HNO41 further supports its utility in research focused on understanding tumor angiogenesis and in evaluating anti-angiogenic therapies for HNSCC.
