摘要: A DNA fragment encoding a novel human-derived tumor cell growth inhibitor can be obtained from a cDNA library originating from human colon tumor cell, using as a DNA probe a DNA fragment encoding mouse human-derived tumor cell growth inhibitor. An expression plasmid bearing a promoter originating from Bacillus brevis, a signal peptide originating from Bacillus brevis and a DNA fragment encoding human-derived tumor cell growth inhibitor downstream of the signal peptide is constructed and Bacillus brevis is transformed by the expression plasmid. The resulting transformant is incubated to secret the novel inhibitor out of the cell so that the novel inhibitor can be produced efficiently.
