The expression levels of the BIRC5, FOXM1, CENPA, KIF4A, PRC1, KIF2C, and TPX2 genes were strongly associated with abundant infiltration of CD4+ T cells, CD8+ T cells, B cells, macrophages, neutrophils, and dendritic cells in HCC (Supplementary Figures S6, S7). Here, BIRC5 is linked to hepatocellular carcinoma.
