We found that AXL and MERTK were expressed at higher levels in liver tissue, lung tissue, endometrial tissue (Figure 2A,D); CD47 was up‐regulated in breast tissue, lung tissue, ovarian cancer, pancreatic cancer and endometrial cancer (Figure 2B); and HAVCR2 showed higher expression in renal clear cell carcinoma (Figure 2C). This evidence concerns the gene CD47 and endometrial cancer.
