GCG and hepatocellular carcinoma: Besides, we also found that “negative regulation of apoptotic process,” “glycogen biosynthetic process,” “regulation of angiogenesis,” “regulation of cyclin-dependent protein serine/threonine kinase activity,” “glucagon signaling pathway,” and “glycolysis/gluconeogenesis” were found to be significantly enriched in patients with high risk scores, indicating that the aforementioned pathological pathways played an important role of the risk signature in influencing the development of HCC.
