- The promoter of the rainbow trout metallothionein B gene ( tMTb) was isolated from genomic DNA by the polymerase chain reaction (PCR ), fused to the bacterial chloramphenicol acetyltransferase (CAT) genein an expression vector, and functionally analyzed in one human cellline and four fish celllines. This promoter exhibited an extremely low basal expression in all celllines and was zincand cadmium-inducible except in the fish melanoma cell line where the promoter was completely inactive. The metal-induced expression patterns wereThe promoter of the rainbow trout metallothionein B gene ( tMTb) was isolated from genomic DNA by the polymerase chain reaction (PCR ), fused to the bacterial chloramphenicol acetyltransferase (CAT) genein an expression vector, and functionally analyzed in one human cellline and four fish celllines. This promoter exhibited an extremely low basal expression in all celllines and was zincand cadmium-inducible except in the fish melanoma cell line where the promoter was completely inactive. The metal-induced expression patterns were cellline-specific. In general the fish promoter was more species- and cell type-specific than its human counterpart. In a transient assay it was functional in developing embryos of the medaka ( Oryzias /atipes). These properties make this promoter suitable for inducible, tissue-specific expression of transgenes and for in vivo studies of gene function and regulation.…
