Abstract
We exploited the emerging potential of gene therapy strategies to design a powerful therapeutic system that combines two key components-AAV vector and [6]-gingerol. In this study, we created an AAV2 construct expressing the proapoptotic protein BIM, which uses HSPG as its primary receptor, to target HSPG-overexpressing melanoma cells. This combination treatment showed promising results in vitro, inducing apoptosis in human melanoma cells. This new platform technology will make a significant contribution to numerous therapeutic applications, most notably for melanoma, including overcoming resistance to conventional anticancer therapies.

Abstract
The giant seaperch iridovirus (GSIV) induces host cell apoptosis by a poorly-understood process. In this study, GSIV is shown to upregulate the pro-apoptotic death genes Bax and Bak at the middle replication stage, and factors in the grouper fin cell line (GF-1) are shown to modulate this process. Studying the mechanism of cell death, we found that upregulated, de novo-synthesized Bax and Bak proteins formed heterodimers. This up-regulation process correlated with mitochondrial membrane potential (MMP) loss, increased caspase-3 activity, and increased apoptotic cell death. All effects were diminished by treatment of infected GF-1 cells with the protein synthesis inhibitor cycloheximide. Interestingly, overexpression of the anti-apoptotic gene Bcl-xL also diminished GSIV-induced mitochondria-mediated cell death, increasing host cell viability and decreasing MMP loss at the early replication stage. Our data suggest that GSIV induces GF-1 apoptotic cell death through up-regulation of the pro-apoptotic genes Bax and Bak, which are regulated by Bcl-xL overexpression on mitochondria in GF-1 cells.
