Simultaneous occurrence of biological processes consisted of intracellular transport, regulation of cyclin-dependent protein kinase activity between the same activated PTHLH feedback-mediated cell adhesion GO network of HCC (compared with the corresponding activated GO network of no-tumor hepatitis/cirrhotic tissues) and the different (compared with the corresponding inhibited PTHLH feedback-mediated cell adhesion GO network of no-tumor hepatitis/cirrhotic tissues). Here, PTHLH is linked to hepatocellular carcinoma.
