To test whether increased Il7r levels upon Zeb2 upregulation are involved in the survival of the injected lymphoblast cells and enhanced leukaemia initiation, we transplanted Zeb2-overexpressing mouse cell lines (P53/R26-Zeb2tg/tg) with and without IL7R-blocking antibody (A7R34) administration. This evidence concerns the gene ZEB2 and leukemia.
