Analyzing the prognosis of m6A, identified that the high expression of mRNA-splicing regulator WTAP (WTAP), Putative RNA-binding protein 15B (RBM15B) and N6-adenosine-methyltransferase catalytic subunit (METTL3) were related to the survival time of HCC patients (Figure S7). The gene discussed is RBM15B; the disease is hepatocellular carcinoma.
