In solid tumors, the overexpression of LAIR1 has been shown on the surfaces of cancer cells in epithelial ovarian cancer [56], cervical cancer [57], breast cancer [58], oral squamous cell carcinoma (OSCC) [59], hepatocellular carcinoma [60], and renal cell carcinoma (RCC) [61], whereas the expression of this IR was not detected in normal equivalent tissue. Here, LAIR1 is linked to breast cancer.
