CD47 and neoplasm: Furthermore, analysis of tumor cells in the GSE149614 dataset revealed that “don't eat me” ligands CD47, CD24, human leukocyte antigen A (HLA‐A), and HLA‐B were significantly upregulated in tumor cells from NUPR1‐high samples, indicating a potential effect of NUPR1+ macrophages on tumor cells (Figure S4B, Supporting Information).
