Several studies subsequently confirmed that lncRNA HAGLROS was upregulated in the expression of various tumors including osteosarcoma, ovarian cancer, intrahepatic cholangiocarcinoma, nephroblastoma, lung cancer and hepatocellular carcinoma, and regulated tumor proliferation, metastasis and EMT processes [13, 16, 31–34]. The gene discussed is HAGLROS; the disease is intrahepatic cholangiocarcinoma.
