Pathogenic and Therapeutic Roles of Bid in Hepatocellular Carcinoma

Abstract: Bid, a Bcl-2 family protein, is a BH3 domain-only agonist. Specific proximal death signals, such as Fas and TNF-á, are connected with the BH3–only pro-apoptotic members to interact with the multidomain molecules of Bak and Bax, which in turn serve as a pathway towards the amplification loop of the intrinsic mitochondrial-mediated apoptotic pathway. Hepatocellular carcinoma (HCC) expresses a low level of Bid and Bid can be regulated by hepatitis X protein, a carcinogen for HCC. Overexpression of Bid or its truncated form tBid can facilitate apoptotic death of HCC cells and significantly enhance the efficacy of chemotherapy towards HCC in vitro and in vivo. It appears that Bid /tBid plays a role in the development of HCC. Application of Bid/tBid to HCC can significantly promote apoptosis of tumor cells, which is therapeutically significant.
