DANCR and hepatocellular carcinoma: 14 showed that lncRNA DANCR induced invasion and migration by suppressing lncRNA‐LET in gastric cancer. Wang et al. and Jiang et al. 15, 16 reported that lncRNA DANCR works as an oncogene and promotes osteosarcoma proliferation and metastasis. Moreover, upregulated expression of lncRNA DANCR was found in hepatocellular carcinoma and DANCR action enhanced stemness features, offering a prognostic biomarker for hepatocellular carcinoma 17.
