We observed that overexpression of YAP rescued the defect in the expression of IL-1β and GM-CSF cytokines and CD47 expression in SIRPγ-knockdown cancer cells (Figure 6J), and also reversed heightened phagocytosis of the SIRPγ-knockdown cancer cells by macrophages (Figure 7, F and J, and Supplemental Figure 6, D and H). Here, IL1B is linked to cancer.
