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.
