SB treatment led to decreased NK cell proportion in cultured PBMC from lung cancer patients (A) CD56+CD3- % NK cells of PBMC from control, smoker and lung tumor patients, cultured as described in Figure 4A , (n^control=4; n^smoker=2; n^tumor=7); (B) Geometric mean of CD119 expression on NK cell (CD56+CD3-) surface after 96h, cultured as described in Figure 4A , analyzed by flow cytometry, (n^control=4; n^tumor=3); (*P < 0.05; **P < 0.01; ****P < 0.0001). One-way ANOVA test was used for figure (A right panel, B left panel) Kruskal-Wallis test was used for figure (A left panel, B right panel). All data are presented as mean values ± SEM.
