As shown in Figure 8E, the risk score positively correlated to T cells regulatory (r=0.266, P<0.001) etc. while was negatively associated to Mast cell resting, B cells naive, Macrophages M1, and T cells CD4 memory resting (Figure 8E), suggesting that these SRGs signature may be a regulator of immunocytes infiltration level in HCC. The gene discussed is CD4; the disease is hepatocellular carcinoma.
