Figure 6. Testing susceptibilities of radioresistant lung cancer cells to NK cell cytotoxicity after adding the inhibitor of MEK/Erk signaling pathway (U0126).

Figure 6

(A) NK cell cytotoxicity tests to A549R26-1 and H157R24-1 cells after adding U0126 (vehicle as control) to tumor/NK cell co-culture. (B and C) NK cell cytotoxicity tests to A549R26-1 and H157R24-1 cells after adding both PD-L1 Ab and U0126 to tumor cell/NK cell co-cultures (B represents data with A549R26-1/H157R24-1 cells and C shows data with parental cells). *p < 0.05, **p < 0.01, ***p < 0.001.
