The former showed that FAM57A expression was significantly correlated with B cells (r=0.396, p=2.29e-14), CD4+ T cells (r=0.355, p=1.09e-11), macrophages (r=0.414, p=9.90e-16), NK cells (r=0.255, p=1.66e-06), T regulatory cells (r=0.366, p=2.39e-12), myeloid dendritic cells (r=0.535, p=6.05e-27), and mast cells (r=0.221, p=3.66e-05) in HCC (Figure 11A). This evidence concerns the gene CD4 and hepatocellular carcinoma.
