SNHG20 and hepatocellular carcinoma: Previous studies have shown that snoRNAs are involved in the development of various tumors.[7] It has been reported that SNORD76 can promote the proliferation of tumor cells in HCC.[8] Other studies have shown that SNHG3, SNHG20, SNHG6, SNORD76, and SNORA47 regulate the development of HCC cells by regulating epithelial-mesenchymal transition (EMT).
