In the thermogram of the experimental group, the autophagy gene HSP90AB1 is highly expressed in the high and low risk groups, and the expressed values of the autophagy genes SQSTM1, RHEB, HDAC1, ATIC, HSPB8, and BIRC5 increase with the enlargement of risk value, which are all regard as high-risk genes of HCC. This evidence concerns the gene HDAC1 and hepatocellular carcinoma.
