Lewis lung carcinoma cells (LLC) were transduced with an empty vector retrovirus (LLC-EV), JAG1-encoded retrovirus (LLC-JAG1) or DLL4-encoded retrovirus (LLC-DLL4) (Supplementary Figure 6A and S6B) and implanted subcutaneously into C57black/6 Lgals3+/+ or Lgals3−/− mice. This evidence concerns the gene LGALS3 and Carcinoma, Lewis Lung.
