LncRNA CTBP1-DT expression was relatively higher in ovarian carcinoma cell lines (SKOV3, A2780, C13*, OV2008, HeyA8 and OVCA433) than in oesophageal carcinoma cells (109), angiosarcoma cells (ISO) and clear cell renal cell carcinoma cells (786–0) (Fig. 1B). The gene discussed is CTBP1; the disease is ovarian carcinoma.
