SNHG1 and liver cancer: Many studies have identified the abnormal expression of many lncRNAs in hepatomas, such as highly upregulated in liver cancer (HULC), HOX transcript antisense RNA (HOTAIR), WD repeat containing antisense to TP53 (WRAP53), differentiation antagonizing non-protein coding RNA (DANCR), maternally expressed gene 3 (MEG3), ZEB1 antisense RNA 1 (ZEB1-AS1), ICAM-1-related (ICR), and small nucleolar RNA host gene 1 (SNHG1) [9–16].
