Further study revealed that KPNA2 expression was positively correlated with infiltration of five kinds of immune cells in HCC including monocytic lineage cells (R = 0.35, p = 4e −12, Fig. 5C), T cells (R = 0.23, p = 1e −05, Fig. 5D), B lineage cells (R = 0.14, p = 0.0071, Fig. 5E), CD8+ T cells (R = 0.14, p = 0.006, Fig. 5F), and myeloid dendritic cells (R = 0.13, p = 0.014, Fig. 5G). The gene discussed is KPNA2; the disease is hepatocellular carcinoma.
