To develop an all-fish gene cassette suitable for gene transfer in aquaculture, the antifreeze protein (AFP) gene promoter from the ocean pout (Macrozoarces americanus) was analyzed for its ability to direct exogenous gene expression both in vitro and in vivo. The ocean pout AFP (opAFP) gene promoter fused to the bacterial chloramphenicol acetyltransferase (CAT) was functionally analyzed in two fish cell lines and in Japanese medaka embryos. The opAFP gene promoter was active in these systems, as demonstrated by the transient expression of CAT activity. These results suggest that the opAFP gene promoter is useful for many other gene transfer experiments. To facilitate use of the opAFP gene promoter as a common and versatile vehicle for fish gene transfers, an expression vector, opAFP-V, was constructed by linking the 2.1-kb opAFP gene promoter, the 63-bp opAFP gene 5' untranslated sequence, and the 1.2-kb opAFP gene 3' sequence by two unique restriction sites, Bg/II and HpaI, respectively. Thus, genes of interest can be inserted into either the Bg/II site or the HpaI site depending on the length of their 5' untranslated sequence. The complete DNA sequence of opAFP-V was determined to facilitate future detailed analysis of integration and expression of the transgene. 相似文献
