Abstract

α-1-antitrypsin (α-1AT) present in large amounts in human serum and. synthesized predominantly in hepatocytes, is the most abundant protease inhibitor and α-1AT mutant proteins are associated with heriditary disorders. To investigate the regulation of the normal human α-1AT gene, we have microinjected fertilized mouse eggs with a 17.5 kb DNA fragment containing the entire gene with 7 kb 5′ and 0.3 kb 3′ flanking sequences. We show that this DNA fragment contains all the information for efficient, accurate and tissue-specific expression. High serum concentration of the human protein was found in three independent transgenic mouse lines. The human α-1AT RNA is transcribed efficiently in liver, kidney and macrophages and we demonstrate that two different promoters are used for the expression in liver and macrophages of the transgenic mice. © 1987 IRL Press Limited, Oxford, England.
