概要：The ME-180 cell line, characterized by its epithelial morphology, is derived from the uterine cervix of a 66-year-old Caucasian female with epidermoid carcinoma.
ME-180 cells present a complex karyotype, ranging from hyperdiploid to hypohexaploid, featuring notable chromosomal abnormalities such as dicentrics, fragmentation, and various markers, reflecting its genetic instability.
ME180 cells are tumorigenic, capable of forming well-differentiated epidermoid carcinoma (grade I) in nude mice, indicative of its origin from a highly invasive squamous cell carcinoma lacking significant keratinization.
ME-180 cells are particularly valuable in cancer and infectious disease research, including studies on sexually transmitted diseases.
A distinctive aspect of ME-180 is its response to tumor necrosis factor alpha (TNF alpha), which inhibits cell growth, offering insights into the cell lines interaction with cytokines and potential therapeutic targets.
Additionally, these cells harbor human papillomavirus (HPV) DNA, showing closer homology to HPV-68 than to HPV-18, which adds a layer of relevance to studies on viral oncogenesis and the development of antiviral strategies.
