Targeted transgenesis using site-specific recombinases is an attractive method to create genetically modified animals as it allows for integration of the transgene in a pre-selected transcriptionally active genomic site. Here we describe the application of recombinase-mediated cassette exchange (RMCE) in cells from a Göttingen minipig with four RMCE acceptor loci, each containing a green fluorescence protein (GFP) marker gene driven by a human UbiC promoter. The four RMCE acceptor loci segregated independent of each other, and expression profiles could be determined in various tissues.

One of the main focus areas in transgenesis is the choice of a promoter driving stable expression over time of the gene of interest. Besides promoter identity, the genomic environment of the transgene plays a pivotal role in transcription regulation. Studies in higher mammals describing transgene expression from a defined locus are very limited.
