The prognostic signature contained five m1A-lncRNAs, including AL031985.3, NRAV, WAC-AS1, AC026412.3, and AC099850.4. However, previous studies reported that the lncRNAs AL031985.3, NRAV, and WAC-AS1 were independent prognostic risk factors in HCC and involved in the functions of pyroptosis, glycolysis, immune function, and ferroptosis [35,36,37,38]. Here, WAC is linked to hepatocellular carcinoma.
