GAS6, as well as the TAM RTKs, also have direct effects on promoting tumor growth.102 Tumor-infiltrating leukocytes upregulate GAS6 and support tumor growth.161 Taken together with its role in the interface of innate and adaptive immunity, the neutralization of TAM ligands or the inhibition of TAM RTK signaling might mediate tumor killing via multiple mechanisms. The gene discussed is GAS6; the disease is neoplasm.
