Meanwhile, PCBP1, RBM25, QKI, TIA1, and RBFOX2 were identified as the core SFs, which owned the most interaction with the relapse-associated AS events, implying their dominant position in determining the relapse-associated AS events in stage I–III HCC (Figure 3A; Supplementary Table S2). The gene discussed is TIA1; the disease is hepatocellular carcinoma.
