For example, ESCCAL-1 was found to be an onco-lncRNA in esophageal cancer development, and high expression of BC200 or MALAT1 has been shown to be a novel predictive marker for ESCC patients who received radical resection.9, 10, 11 Overall, a handful of lncRNAs have documented roles in ESCC.4, 9, 10, 11, 12, 13, 14, 15, 16, 17. Here, CASC9 is linked to esophageal squamous cell carcinoma.
