The distribution of FAT4 expression scores in HCC was analyzed using “immunedeconv.” The results showed that the Tumor Immune Estimation Resource (TIMER) scores of CD4 + /CD8 + T cells, neutrophils, macrophages, and dendritic cells were significantly increased in HCC tissues with high FAT4 expression compared to that in HCC tissues with low FAT4 expression (Fig. 6a). Here, CD4 is linked to neoplasm.
