High CDC20 levels appear to be associated with several other cancers, including serous epithelial ovarian cancer [15], gastric cancer [14], oral cancer [22], and adult T-cell leukemia [23]; high levels are also found in oral squamous cell carcinoma-derived cell lines [22] and the HT29 human adenocarcinoma cell line [13]. The gene discussed is CDC20; the disease is adenocarcinoma.
