Certain tetraspanins known as HCC risk factors have been shown to play roles in HCC growth, survival, neoangiogenesis, invasiveness, and migration [65]; they include CD151, TSPAN5, CD9, CD82, CD63, etc. In terms of HCC, abnormal metabolic pathways and activties can be involved in the development of liver maligancies. This evidence concerns the gene CD151 and hepatocellular carcinoma.
