Comparing patients' CRC liver metastases to normal liver tissue respectively (confront Table 1B for patient characteristics) we found that both Gas6 and Tyro3 were higher expressed within the metastases (p < 0,0001 and p < 0,0001) (Figure 1C, 1D), whereas Axl and Mer did not show a different expression pattern (Supplementary Figure S1C, S1D). The gene discussed is AXL; the disease is colorectal carcinoma.
