Once tumours were established in the lungs, baseline luciferase signals were obtained and mice were then treated for 10 days with cisplatin alone, cisplatin and Nav‐Gal in combination, or their vehicles in combination, using the experimental scheme shown in Figure S5A. Representative images of the luciferase signal at initial‐ and end‐points are shown in Figure S5B. Luciferase signal monitoring demonstrated that concomitant treatment of the mice with cisplatin and Nav‐Gal significantly decreased tumour burden (Figure S5C) compared with cisplatin monotherapy. This evidence concerns the gene GAL and neoplasm.
