The gene suicide system NTR/CB1954 causes ablation of differentiated 3T3L1 adipocytes by apoptosis
The feasibility of ablating differentiated adipocytes and the mechanism of cell ablation with a suitable prodrug activating system is described. The system is based on the use of E. coli nitroreductase (NTR) enzyme that activates certain nitro compounds, such as the antitumor drug CB1954, into cytot...
