PTHLH and hepatocellular carcinoma: Biological processes and occurrence numbers of the same activated high expression (fold change ≥2) PTHLH feedback-mediated cell adhesion GO network in HCC were identified and computed compared with the corresponding low expression activated GO network of no-tumor hepatitis/cirrhotic tissues (HBV or HCV infection), the different compared with the corresponding inhibited PTHLH feedback-mediated cell adhesion GO network of no-tumor hepatitis/cirrhotic tissues, and the same compared with the corresponding inhibited GO network of HCC, respectively.
