Similar to what we observed with the anti-Gas6 treatment, warfarin reduced pancreatic cancer metastasis to the lungs (Figures 7C,D, Supplementary Figures 8A–C) and increased the number and activation of NK cells in lungs (Figures 7E,F) and mesenteric lymph nodes (Figures 7G,H), as shown by the increase in NKp46+ and granzyme B expression. Here, GAS6 is linked to pancreatic neoplasm.
