WTAP promotes the growth of hepatocellular carcinoma by suppressing ETS1’s epigenetic activity in an m6A HuR-dependent manner (Chen et al. 2019), which is consistent with our research results in this paper, but whether WTAP also regulates HCC cell proliferation by regulating cell cycle–associated proteins needs further research. This evidence concerns the gene ETS1 and hepatocellular carcinoma.
