Whether the Wnt enhanceosome’ components BCL9/9l can affect intestinal homeostasis and tumorigenesis is still unclear. Using conditional Bcl9/9l KO mice, the authors of this study show that the BCL9/9l complex is required for intestinal stem cells to drive tissue regeneration and that loss of BCL9/9l suppresses Wnt-driven transformation.
