Lung cancer‐associated transcript 1 was first reported to be involved in smoking‐related lung cancer and was previously called smoke and cancer‐associated LncRNA1 (SCAL1).6 It is also associated with non‐small lung cancer, oesophageal squamous cell carcinoma and colorectal cancer and glioma.7, 8, 9 It is proved that LUCAT1 regulates cell proliferation via epigenetically repressing p21 and p57 expression in non‐small lung cancer.9 Nevertheless, the expression pattern, underlying molecular mechanisms and biological roles of LUCAT1 in HCC tumourigenesis remain unclearly defined. This evidence concerns the gene LUCAT1 and glioma.
