Abstract
Altered levels of histone acetylation are associated with changes in chromosomal gene expression. Thus, the specific acetylation of histones bound to plasmid DNA might increase transgene expression. Previously, the expression of the histone acetyltransferase domain of CREB-binding protein fused to the sequence-dependent DNA binding domain of GAL4 (GAL4-HAT) successfully improved reporter gene expression in cultured cells [J. Biosci. Bioengng. 123, 277-280 (2017)]. In this study, the same approach was applied for transgene expression in mice. The activator and reporter plasmid DNAs bearing the genes for GAL4-HAT and Gaussia princeps luciferase, respectively, were co-administered into the mouse liver by hydrodynamics-based tail vein injection, and the Gaussia luciferase activity in serum was measured for two weeks. Unexpectedly, the co-injection of the GAL4-HAT and luciferase plasmid DNAs seemed to decrease, rather than increase, luciferase expression. Moreover, the co-injection apparently reduced the amount of luciferase DNA in the liver. These results indicated that this system is ineffective in vivo and suggested the exclusion of hepatic cells expressing GAL4-HAT.
