Pu et al. found that MAGI2-AS3 might attract KDM1A to encourage the demethylation of H3K4me2 in the RACGAP1 promoter, which would ultimately lower the level of RACGAP1 expression and control the proliferative, migratory, and invading capacities of HCC cells [46]. The gene discussed is RACGAP1; the disease is hepatocellular carcinoma.
