SNHG6 and hepatocellular carcinoma: Guo et al7 found that lncRNA SNHG6 is not only an oncogene in hepatocarcinogenesis but also a potential prognostic indicator for hepatocellular carcinoma (HCC), and, by inhibiting S‐adenosylmethionine production in HCC, dysregulation of SNHG6 can lead to aberrant genome‐wide hypomethylation and further disturb the treatment of HCC.
