Forced expression of miR‐942 significantly changes the drug sensitive cells to resistant in hepatocellular carcinoma and gastric cancer.16 In esophageal squamous cell carcinoma, miR‐942 promotes cancer stem cell‐like traits through activation of Wnt/β‐catenin signalling pathway.17 In colorectal cancer, long non‐coding RNA linc00675 suppresses cell proliferation and metastasis via regulating miR‐942.18 Here, we found that miR‐942 was down‐regulated in ovarian cancer. This evidence concerns the gene TMEM238L and esophageal squamous cell carcinoma.
