However, the critical role of CD47 in gastric cancer and its association with tumor associated macrophages remain unclear. Methods Tumor tissues of gastric cancer from Zhongshan Hospital and data from GSE62254, GSE84437 and TCGA datasets were analyzed cancer cells is the expression of CD47, a cell-surface protein that interacts with signal regulatory protein α on macrophages to block phagocytosis (15–17). HIF-1 stimulates CD47 expression in hyp-oxicbreastcancercells (18).However, whether chemotherapyalso affects the expression of CD47 has not been investigated. CD47 is an antiphagocytic molecule that contributes to tumor cell resistance in host immune surveillance.

Cd47 cancer

CD47 was first identified as a tumor antigen on human ovarian cancer in the 1980s. Integrin-associated protein (CD47) is ubiquitously expressed on the surface of cells and functions as an identifier of self. In blood cancer, tumor cells expressing CD47 evade phagocytosis by macrophages, leading to a poor patient prognosis. CD47, a ‘marker-of-self’ protein that is overexpressed broadly across tumor types, is emerging as a novel potent macrophage immune checkpoint for cancer immunotherapy. Recently, CD47 blockade by Hu5F9-G4 has shown promise combined with Rituximab in non-Hodgkin’s lymphoma. CD47 is overexpressed in many human cancers, its level positively correlates with tumor invasion and metastasis.

ever, CD47 is found to be overexpressed on cancer cells. CD47–SIRPα interaction inhibits macrophage phagocytosis, allowing cancer cells to escape immune surveillance. Current focus in immunotherapy has been targeted toward inhibiting CD47–SIRPα interaction via anti-CD47 antibodies.
