Six risk model genes interaction and core gene verification. (A) Expression of the six genes in the risk signature in the high and low risk groups. (B) Correlation of the six genes in the train group. (C) Correlation of the six genes in the test group. (D) Correlation between the level of immune cell infiltration and the six genes in the risk signature. (E) Correlation clustering of HCC infiltrating immune cells. (F) qRT-PCR of CD8A expression differences in HCC tissues and normal tissues. (G) Normal and cancer images of CD8A expression in liver tissues (100× and 200×) detected by IHC staining. * represents P<0.05, ** represents P<0.01, *** represents P<0.001.
