Abstract

  • We inserted the sequence coding for the cytoplasmic portion of the human MET receptor into an 18-kb genomic fragment containing the entire human A1AT gene (encoding alpha-1-antitrypsin). Stringent control of gene expression, at the transcriptional, post-transcriptional and translational levels, was ensured by insertion of the MET open reading frame into A1AT, thus maintaining: (i) all the elements that confer tissue-specific transcription initiation, (ii) all the sequences involved in transcript processing and (iii) all the sequences which influence messenger stability and translational efficiency. The expression pattern of this vector in transgenic mice was identical to that of the human A1AT transgene, as well as to that of A1AT in humans with regard to both temporal and tissue-specific regulation.
