In this study, Yin et al. identified genitalia family member 1 (SMG1) -involved in nonsense-mediated mRNA decay- as positively regulated by MAGI2-AS3, and showed that SMG1 knockdown reverses the suppressive function of MAGI2-AS3 in HCC cells [217]. This evidence concerns the gene MAGI2 and hepatocellular carcinoma.
