Furthermore, TYRO3, AXL, MERTK, and their corresponding ligands are involved in independent signaling pathways, with PROS1/AXL signaling pathway-mediated tumour proliferation being dominant in oral squamous cell carcinoma, whereas the other two TAM receptors (MERTK and TYRO3) are nearly undetectable. The gene discussed is MERTK; the disease is neoplasm.
