The gene encoding E. coli nitroreductase (NTR) was expressed in the luminal cells of the mammary gland of transgenic mice using the ovine beta-lactoglobulin promoter. Treatment of NTR expressing animals with the prodrug CB1954 (5-aziridin-1-yl-2-4-dinitrobenzamide) resulted in a rapid and selective killing of this population of cells whereas the closely associated myoepithelial cells were unaffected. NTR-mediated inducible cell ablation offers a number of advantages over the use of HSV1-tk for the selective killing of cells in vivo.
