GAS6 and lung cancer: As shown in Figure 2B and 2C, a similar inhibitory effect of DN10764 on GAS6-induced AXL signaling was observed in the Hs578T cell line, another AXL-expressing breast cancer cell line, and in the A549/C is cell line, which is a cisplatin-resistant derivative of the human A549 lung cancer cell line that expresses significantly more AXL compared to the parental A549 cell line [11].
