Dong et al regarded that SNHG8 promoted liver cancer tumorigenesis and pulmonary metastasis via sponging MIR149. 94SNHG12 was the host gene of four small nucleolar RNAs—SNORA44, SNORA61, SNORA16A and SNORD99. SNHG12 was expressed at a significantly higher level in cancerous tissues than in normal tissues. Here, SNHG12 is linked to liver cancer.
