Figure 10. The expression validation of the genes in the FA score by RT-qPCR and WB. (A) Expression levels of 5 genes in LUAD and matched paracancerous tissues. (B) Expression levels of 5 genes in the normal lung epithelial cell line BEAS-2B and two LUAD cell lines (HCC827, A549). ns, not significant, *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001. T, tumor tissues; P, paracancerous tissues.
