CD47 and neoplasm: Similar to Cd47 knockdown (Figure 2, J–L), we observed that miR-34a overexpression strongly inhibited CD47 protein levels and promoted tumor phagocytosis by M1 macrophages; cotreatment with AAV-CD47 in mice completely reversed the effect of miR-34a (Figure 4, D–G, and Supplemental Figure 10, E–G).
