VAPA and hepatocellular carcinoma: Statistical analysis revealed that the HCC patients with high VAPA‐expression exhibited significantly shorter bone‐metastasis‐free survival compared with HCC patients with low VAPA‐expression and VAPA expression could be recognized as an independent prognostic factor for survival in patients with HCC bone‐metastasis (p = 0.003, Figure 2F; Tables S2–S4, Supporting Information), which provided the further evidence to link VAPA overexpression with HCC bone‐metastasis.
