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). This evidence concerns the gene CTBP1 and clear cell renal carcinoma.
