NCOA3 and hepatocellular carcinoma: Further studies are required to elucidate cells expressing viral proteins, which can interfere not only in splicing events as described earlier, but can also stabilize cellular protein products involved in many important processes: hepatitis B virus × protein (HBx) was reported to stabilize amplified in breast cancer 1 protein (AIB1) and cooperate with it to promote human hepatocellular carcinoma cell invasiveness (39) and it was also reported that cellular proteins were actively stabilized by HSV-1 viral gene products (40).
